The best startup tech stack in 2026: a lean default and 37 tools by layer

·

A startup stack fails in two ways. It grows a tool for every idea until nobody knows what each one is for, or it measures everything users do and never asks them why. The fix for both is the same: pick one default per layer, add a tool only when you can name the job it does, and put a way to hear from customers next to your analytics from day one.

This guide is for founders of small web software startups choosing the stack and the team’s tools. It gives a lean default stack, sorts 37 tools into six layers with what each costs and when to pick its neighbor instead, decides the close calls from Supabase versus Neon to Stripe versus Paddle, and adds up the monthly bill.

Key takeaways

  1. Put a way to hear customers in the stack from day one, next to analytics. Our default is Feedbaq: connect it to your AI agent for free and the agent becomes your expert researcher, building studies in which customers explain by voice or show you the problem on screen. Collecting responses costs $49 a month.
  2. Pick one default per layer and add a tool only when you can name the job it does. For a small web startup that means Cursor, GitHub and Linear to build, Supabase, Vercel and Sentry to run the app, PostHog and Feedbaq to learn, and Stripe and Resend to get paid and send email.
  3. A solo founder can run this stack for $65 a month plus payment fees, and $114 in a month you collect customer answers with Feedbaq. Everything beyond Cursor Pro, Supabase Pro and Vercel Pro stays on free plans.
  4. Vercel’s free Hobby plan is for personal, non-commercial projects. Budget $20 a month for Pro before you charge anyone.

Start here

Find the line that describes you. Each names the tool we would start with and the one to compare it with.

  • You need to know why users sign up, stall or leave. Start with Feedbaq: free in your AI agent, which builds the study, and $49 a month while you collect answers. Pair it with PostHog to find whom to ask.
  • You write code and are starting today. Start with Cursor, Supabase and Vercel. Compare Claude if you prefer an agent in the terminal.
  • You do not write code. Start with Lovable and get the first version in front of customers. Compare Replit if you want to see the code as it grows.
  • Your product is live, collaborative or real-time. Start with Convex. Compare Supabase.
  • You have users and a funnel that leaks. Start with PostHog to find the step, then Feedbaq to ask those users why. Compare Amplitude for analytics.
  • You sell to customers in many countries. Start with Paddle. Compare Stripe if most revenue comes from one country.
  • You need background workers or long-running jobs. Start with Railway. Compare Render for a fixed price per instance.
  • You are building a sales pipeline. Start with HubSpot’s free CRM. Add Customer.io once product events should trigger email.

The lean default stack

Nine layers, one default each, and the moment you would switch. Hearing from customers is one of the nine, not an extra for later. This stack assumes a small team building a TypeScript web app, such as Next.js. The last column is the point of the table: switch or add only when that sentence becomes true for you.

One default per layer, and ears next to your eyes

Every tool you add is a bill, a login, a failure point and a thing someone must learn. Dan McKinley’s essay “Choose Boring Technology” gives each company about three innovation tokens to spend on new technology, and argues the supply stays fixed for a long while. The same holds for tools. Pick one default per layer, spend your tokens on the product, and write down the job before you add anything. “We might need it” is not a job. “Support replies take a day because questions arrive in four inboxes” is.

The layer most early stacks leave out is hearing from customers. Founders install analytics in the first week and talk to customers when they find the time. That gets the order of risk wrong. In CB Insights’ March 2026 analysis of 431 venture-backed startups that shut down since 2023, running out of money topped the list at 70%, but the authors call it the final cause, not the root one. Poor product-market fit came next at 43%, and two-thirds of those failures were early-stage companies that never found a market.

No tool finds a market for you. What a stack can do is make the question cheap to ask. Analytics shows where people drop off; it cannot tell you why they left. So put a way to ask next to your analytics from day one, and use the two together: the funnel tells you whom to ask, and their answers tell you what to build.

Feedbaq answers that layer better than a survey or a calendar of calls. A survey gets a typed line; spoken answers run about three times longer, 43.8 words against 14.2 in a 2024 experiment by Lenzner, Höhne and Gavras. Calls go deep, but only with the customers who accept a slot. With Feedbaq, everyone you invite can answer by voice or show you the step on screen, and the AI follows up on what each person said. Your own agent in Cursor, Claude or ChatGPT becomes your expert researcher for free: it builds the study and reads every answer, and you pay $49 a month only while you collect responses.

How we chose

This guide is desk research, not a hands-on test. We read each vendor’s pricing page, product pages and documentation on 7 October 2026; where a page would not show a price, the source note gives our 1 October 2026 check. The sources are linked at the end.

  • A job a small web startup has. Each tool builds the product, runs it, helps you learn from customers, takes payment, runs the team or markets the product.
  • A price or a named customer. Every tool publishes a price or a free plan.
  • A reason to pick it over its neighbor. Each entry names the nearest alternative and when to choose it instead.
  • A small team’s budget. We left out tools sold only through enterprise contracts.

We make Feedbaq, and we recommend it first for hearing from customers. For tools that help a product manager specify and plan, see our guides to product management tools and AI tools for product managers.

Build the product

Choose your build tool by who writes the code, not by which demo impressed you. If someone on the team writes code, use Cursor, or Claude Code or Codex if you prefer an agent in the terminal, and keep the code in your own GitHub repository. If nobody does, Lovable or Replit gets a working product in front of customers sooner, and you can move to a repository when an engineer joins. Figma earns its seat when someone designs screens or you test flows before building them.

1. Cursor

cursor.com

Cursor is a code editor built around AI agents that work across your whole repository, with cloud agents that run while you do something else and Bugbot for code review.

You bring
Your repository and a task described in plain words
You get
Changes across files that you review, test and commit
Example
Ask the agent to add team invites on top of Supabase auth, read the diff, run the tests and open a pull request.
Shortlist it if
Someone on the team writes or reviews code, and you want the product in a repository you own from the first day.
Choose it over
Lovable or Replit when the product will outgrow a prototype and you want every line in your own repository.
Think twice if
Nobody on the team can read a diff yet: start in Lovable and move to Cursor when an engineer joins.
Price
Pro $20 a month; Teams $40 a user a month
Free plan
Hobby: limited agent requests, no card required
Watch the extra costs
Model use beyond what the plan includes is billed on demand.

2. Claude

claude.com

Anthropic’s assistant for writing, research and code. Pro includes Claude Code, an agent that works in your terminal and repository, and connectors let Claude read the tools in your stack, Feedbaq among them.

You bring
Your codebase, your documents and the tools you connect
You get
Code changes, specs and research summaries that quote the sources Claude can read
Example
With Feedbaq connected, ask which reasons trial users gave for stalling, with a link to each quote, then ask Claude Code to draft the fix.
Shortlist it if
You want one $20 plan that covers code, writing and research.
Choose it over
ChatGPT when you want Claude Code and Claude’s connector directory; the two are close, so pick the one your team already uses.
Think twice if
You already pay for Cursor and only need help with code: a second $20 seat should earn its place with writing and research.
Price
Pro $20 a month, or $17 billed annually; Team $25 a seat monthly, $20 billed annually
Free plan
Yes, with connectors; Claude Code needs Pro
Watch the extra costs
If your product calls Claude, the API is billed separately by tokens.

3. ChatGPT

chatgpt.com

OpenAI’s assistant for research, writing, data analysis and files. Every plan includes Codex, OpenAI’s coding agent.

You bring
Files, spreadsheets and documents, a repository for Codex, and the apps you connect
You get
Analyses, drafts, research reports and code changes
Example
Upload a funnel export and ask which signup sources retain best, then ask Codex to add the tracking event you are missing.
Shortlist it if
Your team already works in ChatGPT, or you analyze exported data often.
Choose it over
Claude when your team already shares work in ChatGPT; for a founder the two are close, so the shared workspace decides.
Think twice if
You want a Business workspace for one person: Business needs at least two users.
Price
Plus $20 a month; Business $20 a user a month billed annually, $25 monthly, two-user minimum
Free plan
Yes, and Codex is included
Watch the extra costs
If your product calls OpenAI’s models, the API is billed separately.

4. Lovable

lovable.dev

Lovable builds a working web app from a conversation. One credit balance pays for building, hosting on Lovable Cloud and the AI features inside your app.

You bring
A description of the app, and changes asked for in plain words
You get
A deployed web app you keep changing in chat
Example
Describe a booking tool for dog groomers, put the working version in front of five groomers, and change it the same afternoon.
Shortlist it if
You are a non-technical founder and need a working product in front of customers before you hire an engineer.
Choose it over
Cursor when nobody on the team writes code yet; Replit when you want the conversation, not the code, to be where you work.
Think twice if
You will change the app all day: every change spends credits, and the same balance pays for hosting and AI in your app.
Price
Pro from $25 a month for 100 credits, or $21 billed annually; Business from $50
Free plan
Yes: 5 build credits a day, up to 30 a month, plus monthly grants of 20 Cloud credits and 4 for AI in your app
Watch the extra costs
Pro top-ups cost $15 per 50 credits.

5. Replit

replit.com

Replit is a browser workspace where an AI agent builds, runs and publishes your app, with the code, database and hosting in one place.

You bring
A description of the app, or an existing project
You get
A running app and its code, published from the same workspace
Example
Build an internal admin tool for support with the agent, publish it, and send the link to the team.
Shortlist it if
You want to build and host in one browser tab and still see every file the agent writes.
Choose it over
Lovable when you want the code open next to the agent and up to 15 collaborators on Pro.
Think twice if
Your engineers already have a repository and pipeline: Replit works best when everything stays inside Replit.
Price
Core $20 a month, or $18 billed annually; Pro $100, or $90 billed annually
Free plan
None on the pricing page; Core includes up to 30 hours of chat in Free Mode
Watch the extra costs
Core includes $20 and Pro $100 toward stronger models; use beyond that is billed.

6. Figma

figma.com

Figma is the shared canvas for interface design and prototypes. Figma Make turns a prompt or a design into a working prototype.

You bring
Screens, flows and components, or a prompt for Figma Make
You get
Designs, clickable prototypes and specs engineers build from
Example
Prototype a new onboarding flow in Figma Make and show it to five customers before anyone writes the real version.
Shortlist it if
Someone on the team designs screens, or you test flows with customers before you build them.
Choose it over
Designing straight in code when you want to compare several flows before you commit to one.
Think twice if
You are a solo technical founder: Cursor and a component library can carry you until a designer joins.
Price
Professional Full seat $16 a month, Dev seat $12, Collab seat $3, billed annually
Free plan
Starter: unlimited drafts, 150 AI credits a day, up to 500 a month
Watch the extra costs
A Full seat includes 3,000 AI credits a month for Make and other AI features.

Run the app

Start with one backend that bundles data, sign-in and storage, and one host that deploys from GitHub. Supabase and Vercel cover most small web apps, and Sentry tells you when something breaks. Neon, Convex and Clerk earn a place when you can name what Supabase does not do for you. Cloudflare, Railway and Render are for specific needs: lower running costs, background workers, or a fixed price per server.

7. Supabase

supabase.com

Supabase gives you a managed Postgres database with sign-in, file storage and an API in one project and one dashboard.

You bring
Your data model and the sign-in methods you need
You get
A database, user accounts and file storage behind one API
Example
Model teams, members and invites as Postgres tables, turn on Google sign-in, and keep uploads in the same project.
Shortlist it if
You want relational data, sign-in and storage working on day one without stitching three services together.
Choose it over
Neon when you want sign-in with social providers, multi-factor auth and audit logs in the same product as the data; Convex when you want standard Postgres and SQL you can take anywhere.
Think twice if
You launch on the free plan: free projects pause after a week of inactivity, so move to Pro before customers arrive.
Price
Pro from $25 a month, with $10 of compute credit; extra projects from $10 a month
Free plan
Yes: two active projects, a 500 MB database and 50,000 monthly active users; paused after a week of inactivity
Watch the extra costs
Compute above the credit, disk beyond 8 GB, egress beyond 250 GB and users beyond 100,000 are billed by usage.

8. Neon

neon.com

Neon is serverless Postgres that scales compute with your load and branches the database like code. It now adds managed auth and object storage.

You bring
A Postgres schema and the app that queries it
You get
A database that scales with load, and a branch for each pull request or experiment
Example
Give each pull request its own database branch, test the migration there, and delete the branch when it merges.
Shortlist it if
You want standard Postgres, compute billed by use, and database branches in your workflow.
Choose it over
Supabase when the database is what you need and you will choose sign-in and hosting yourself.
Think twice if
You want a fixed monthly bill: Launch is usage-based, so a busy month costs more.
Price
Launch is usage-based: $0.106 per compute-hour and $0.35 per GB-month; Neon puts typical spend at $15 a month
Free plan
Yes: 100 projects, 100 compute-hours a month and 1 GB of storage per project

9. Convex

convex.dev

Convex is a reactive backend: your queries and server functions are TypeScript in your repository, and every open client updates when the data changes.

You bring
Your data model and server functions, written in TypeScript
You get
A hosted backend whose queries push updates to every client
Example
Build a shared board where one person’s change appears for everyone else without writing any sync code.
Shortlist it if
Your product is collaborative or live, and the whole team writes TypeScript.
Choose it over
Supabase or Neon when live updates are the core of the product, not a feature you add later.
Think twice if
You want SQL and a database other tools can query directly: Convex has its own model, and leaving means rewriting your data layer.
Price
Professional $25 a developer a month plus usage
Free plan
Free & Starter: free, then pay as you go, for 1 to 6 developers
Watch the extra costs
Function calls, compute, storage and bandwidth beyond the included amounts are billed by usage.

10. Clerk

clerk.com

Clerk is a sign-in service with ready-made screens for sign-up, user profiles and organizations, which gives a B2B app team accounts without building them.

You bring
Your app, the sign-in methods you want and your organization rules
You get
Prebuilt sign-in, profiles, invites and roles inside your app
Example
Add organizations with invites and admin and member roles to a B2B app, instead of building them on your own tables.
Shortlist it if
Your B2B app needs organizations, invites and roles, and your backend’s auth does not give you the screens.
Choose it over
Supabase Auth when polished account screens and organization management matter more than one vendor fewer.
Think twice if
You already use Supabase or Neon auth: a second sign-in service adds a bill and a sync job for one feature.
Price
Pro $25 a month, or $20 billed annually
Free plan
Yes: 50,000 monthly retained users per app
Watch the extra costs
Retained users beyond 50,000 cost $0.02 each a month; some security features are add-ons.

11. Vercel

vercel.com

Vercel deploys your web app from GitHub, with a preview link for every pull request. It is the company behind Next.js.

You bring
A GitHub repository with a Next.js or other frontend app
You get
Production and preview deployments on a global CDN, with logs and traffic insights
Example
Open a pull request, send its preview link to the customer who reported the bug, and merge once they confirm the fix.
Shortlist it if
You build with Next.js and want deploys you never think about.
Choose it over
Cloudflare or Railway when you want the least setup for a Next.js app.
Think twice if
You plan to launch on Hobby: it is for personal, non-commercial use only, so a startup needs Pro.
Price
Pro $20 a month with one deploying seat and $20 of usage credit; extra seats $20 a month each
Free plan
Hobby: free for personal, non-commercial projects only
Watch the extra costs
Usage beyond the $20 credit is billed on demand; add-ons such as password protection cost extra.

12. Cloudflare Workers

workers.cloudflare.com

Cloudflare Workers runs your app on Cloudflare’s network, next to storage such as KV, D1 and R2, and charges nothing for data transfer.

You bring
An app built for the Workers runtime, or adapted to it
You get
An app served from Cloudflare’s network, billed by requests and CPU time
Example
Run a Next.js app on Workers through the OpenNext adapter.
Shortlist it if
You want low fixed costs and no bandwidth bill, and someone on the team will learn the runtime.
Choose it over
Vercel when bandwidth and request costs matter more than deploys that need no setup.
Think twice if
You want deploys you never think about: Workers is its own runtime, and Next.js runs through an adapter with settings to learn.
Price
Workers Paid from $5 a month per account, with 10 million requests included
Free plan
Yes: 100,000 requests a day
Watch the extra costs
$0.30 per extra million requests and $0.02 per extra million CPU milliseconds; D1, R2 and other products are priced separately.

13. Railway

railway.com

Railway runs services, background workers, cron jobs and databases from your repository, billed by the resources they use.

You bring
A repository or container image for each service
You get
Running services and databases in one project, billed by the second
Example
Run the API, a queue worker and a Postgres database for a video-processing feature in one project.
Shortlist it if
Your app needs long-running processes, such as workers or websockets, that serverless hosting handles badly.
Choose it over
Render when you want billing by use from a $5 minimum rather than a fixed price per instance.
Think twice if
Your services run around the clock: memory costs about $10 per GB a month while running, so size each service.
Price
Hobby $5 minimum a month, including $5 of usage; Pro $20 minimum, including $20
Free plan
30-day trial with $5 of credit, then $1 a month

14. Render

render.com

Render hosts web services, background workers, cron jobs and managed Postgres at a fixed price per instance.

You bring
A repository and an instance size for each service
You get
Web services, workers and databases with a bill you know in advance
Example
Run a Python API on a $7 instance with a $6 Postgres database, and know the bill before the month starts.
Shortlist it if
You run a conventional server app and want a predictable bill per instance.
Choose it over
Railway when you would rather pay a fixed price per instance than by the second.
Think twice if
You plan to run production on free instances: they come with limits, so put customers on a paid instance.
Price
Workspace $0 (Hobby) or $25 a month (Pro), plus compute: web services from $7 a month, Postgres from $6
Free plan
Yes: free web service and Postgres instances, with limits

15. Sentry

sentry.io

Sentry catches errors and slow requests in your app, ties each one to the release and the code behind it, and alerts the owner.

You bring
The Sentry SDK in your frontend and backend
You get
Grouped errors with stack traces, traces and the release that introduced them
Example
A customer’s checkout fails; Sentry shows the stack trace, the request and the release that broke it before the customer writes in.
Shortlist it if
Customers use the app and you want to hear about failures before they tell you.
Choose it over
PostHog’s error tracking when errors and performance traces deserve a tool of their own.
Think twice if
You are a team: the free Developer plan is limited to one user, and Team costs $26 a month.
Price
Team $26 a month and Business $80 a month, billed annually
Free plan
Developer: free for one user
Watch the extra costs
Events beyond the plan’s data allowance are billed; Seer, the AI debugging agent, needs its own subscription.

Learn from customers

Hearing from customers belongs in the stack from day one, in the same week as analytics. Poor product-market fit is behind 43% of the shutdowns CB Insights studied, and analytics can only report it after the fact: it shows where people drop off, never why. Feedbaq is our default for the why. It costs nothing until you collect answers, your AI agent builds the studies, and customers explain in their own voices or show you on screen, with AI follow-ups on what each one said. PostHog is the default for the what: free up to a million events, with replays in the same install. Amplitude and Mixpanel are analytics alternatives, Clarity watches your marketing site for free, and Tally runs waitlist and intake forms. For what to ask, see our customer discovery questions.

16. Feedbaq

feedbaq.to

Made by us

Feedbaq gets you the depth of a customer call without the calendar. Connect it to your AI agent for free and the agent becomes your expert researcher: it plans and builds the study. You share the link, and people answer in their browser by voice, by narrating their screen while they use your product, or by text and choice, while an AI follows up on what each person said.

Analytics shows where users drop off; Feedbaq asks them why. Send the users who stalled at a step a study link. They answer in their browser with no account, by voice or by narrating their screen while they try the step, and the AI asks up to three follow-ups about what each person said. You get the explanations a round of calls would give you, without booking one.

Your AI agent becomes your expert researcher, free. Your agent in Cursor, Claude or ChatGPT already knows your product. Connected to Feedbaq over MCP, it plans and builds the study around the drop-off, and you preview it for as long as you like at no cost. When you publish, it reads every answer and links each quote to the second it was said; collecting responses costs $49 a month. Feedbaq is in Claude’s connector directory, and the MCP help page covers Cursor, ChatGPT, Codex and Grok.

You can check every finding yourself. Transcripts are timed word by word, so a click plays the recording from that word. Before you change the onboarding, you hear the hesitation and watch what was on screen when they said it.

You bring
A question your analytics raised, the users you can reach, and your agent’s context on the product
You get
Voice and screen recordings with transcripts timed word by word, follow-up answers, topic counts, and quotes linked to the moment they were said
Example
PostHog shows trial users stalling where they connect their data. Ask those users to try the step on screen and talk it through. When someone says “I didn’t know which key to paste”, the AI asks where they looked for it.
Shortlist it if
Your analytics shows where users drop off and you need them to tell you why, without booking calls.
Choose it over
PostHog surveys or Tally, because a typed one-liner tells you what happened and Feedbaq’s spoken answers and follow-ups tell you why; booked calls, because calls go deep only with the customers who accept a slot, and Feedbaq hears from everyone you invite.
Think twice if
You have no users yet and nobody to invite: Feedbaq asks people you can reach, so pair it with a recruitment panel for strangers.
Price
Free in your AI agent; $49 a month to publish and collect responses, with every feature and unlimited studies and team members
Free plan
Yes: connect your AI agent, plan and build studies, and preview them, free

17. PostHog

posthog.com

PostHog combines product analytics, session replay, surveys, feature flags, experiments and error tracking, with PostHog AI to answer questions about your data.

You bring
Events from your app, and questions in plain words
You get
Funnels, retention charts and the session replays of the people behind them
Example
Find the step where new trial users stop, then watch five replays of people stalling there.
Shortlist it if
You are setting up analytics for a new product and want behavior, replays and in-app surveys from one install.
Choose it over
Amplitude or Mixpanel when you also want replays, flags, surveys and error tracking from one vendor, free up to the allowances.
Think twice if
Nobody owns instrumentation: every chart is only as good as the events you send.
Price
Usage-based beyond the free allowances, priced per product
Free plan
Every month: 1M events, 5,000 replays, 1,500 survey responses, 100,000 exceptions and 500 AI credits; unlimited team members

18. Amplitude

amplitude.com

Amplitude is product analytics with session replay, experiments, feature flags, surveys, AI agents and an MCP server on every plan.

You bring
Tracked events and the customer feedback you connect
You get
Retention, funnel and cohort analysis, and agent answers about your data
Example
Ask its agent which first-week actions separate accounts still active at day 90.
Shortlist it if
Measurement will drive most of your product decisions, or your team already knows Amplitude.
Choose it over
PostHog when you want analytics-first depth and a free plan with 2M events a month.
Think twice if
You will outgrow Plus: Growth and Enterprise are priced on request.
Price
Plus starts at $0 and scales with event volume beyond 2M; Growth and Enterprise on request
Free plan
Yes: 2M events a month, replay, experiments, AI agents and MCP, unlimited seats; startups under $10M raised and 20 people get a year of Growth free

19. Mixpanel

You get
Funnels, retention curves and cohort comparisons, with replays of the sessions
Example
From Claude, ask Mixpanel through its MCP server how week-two retention changed after the new onboarding.
Shortlist it if
You want a focused analytics tool and no wider suite to adopt.

PostHog or Amplitude when focused event analysis is all you need.
Think twice if
Nobody keeps a tracking plan: messy event names make every answer suspect.

Free plan
Yes: up to 1M events and 10,000 session replays a month

20. Microsoft Clarity

A tracking script on your site or app
You get
Session recordings, click and scroll heatmaps, and AI insights

See how far visitors scroll on the pricing page and where they click before they leave.
Shortlist it if
You want to see how visitors use your marketing site and pay nothing for it.
Choose it over
PostHog replay on a busy marketing site, so the product’s free allowance goes to the product.
Think twice if
You need funnels and retention for the product itself: Clarity shows behavior on pages, not product analytics.
Price
Free
Free plan
Yes, with no traffic limits

21. Tally

tally.so

Tally is a form builder with unlimited free forms and submissions, conditional logic, payments and file uploads. Its MCP server lets Claude, ChatGPT or Cursor create forms and read submissions.

Your questions and the logic between them
You get
Structured submissions in Tally or sent on to Google Sheets, Notion and other tools
Example
Run a waitlist form that asks each person’s role and current tool, and send every submission to a Notion database.

A typed or multiple-choice answer is enough: waitlists, intake forms and quick polls.
Choose it over
Paid form builders for waitlists, intake and polls, because its free plan has no submission limit.
Think twice if
You need the reason behind an answer: a form cannot follow up on what someone wrote, and Feedbaq asks by voice and follows up.
Price
Pro $29 a month; Business $89 a month
Free plan
Yes: unlimited forms and submissions within fair use; the MCP server is free on every plan

Get paid and talk to customers

Take payments with Stripe and send app email with Resend; add the rest when the volume forces it. Paddle replaces Stripe when you sell across borders and want someone else to handle the tax. Brevo and Customer.io are for marketing and lifecycle email, Crisp for support once one inbox is not enough, and HubSpot once a sales pipeline outgrows a spreadsheet.

22. Stripe

Price
2.9% + 30¢ per successful domestic card transaction in the US
Free plan
No monthly fee; you pay per transaction
Watch the extra costs
Billing adds 0.7% of billing volume, and Tax adds 0.5% per transaction where you are registered.

Example
Sell to customers in the EU, the UK and the US without registering for sales tax in each place.
Shortlist it if
You sell software across borders and want sales tax and VAT off your plate.

Stripe when tax compliance across countries would cost you more than the higher fee.

Price
5% + 50¢ per transaction; custom pricing on request

Free plan
Yes: 3,000 emails a month, 100 a day

Shortlist it if
You want newsletters and simple automation at a small-team price.
Choose it over
Customer.io when you send to a list on a schedule, not from product events, and want to pay $9, not $100.
Think twice if
Your emails should react to what people do in the product: Customer.io is built for that.
Price

Free plan
Yes: up to 300 emails a day

Brevo when messages should follow product behavior rather than a send schedule.
Think twice if
Your events are not in place yet: journeys depend on them, so start with Resend and add this later.
Price
Essentials from $100 a month billed monthly, with 5,000 profiles and 1 million emails; Premium from $1,000 a month billed yearly
Free plan
No; companies that raised under $10M can apply for a free year

A spreadsheet once more than one person follows up with prospects.
Think twice if
You sell self-serve with no sales calls: you do not need a CRM yet.
Price
Starter from $20 a seat a month; a limited-time offer cut it to $7 to $10 a seat on 7 October 2026
Free plan
Yes: free CRM tools for up to two users
Watch the extra costs

Run the team

Put the code, the commitments and the decisions in three places the company owns. GitHub holds the code and Linear holds what the team promised to build. Notion holds why. Slack is for the conversation in between, and Google Workspace makes sure every login belongs to the company, not to one person’s Gmail.

29. GitHub

github.com

GitHub hosts your repositories, pull requests and code review, and runs your tests and deploys with GitHub Actions.

You bring
Your code and the checks it must pass
You get
A reviewed history of every change, with tests on each pull request
Example
Require passing tests before anything merges to main, and let Vercel build a preview for each pull request.
Shortlist it if
You are starting a code project: every other developer tool in this list connects to it.
Choose it over
Keeping the code only inside Lovable or Replit, because the company should own the code from the first commit.
Think twice if
Your test runs grow long: Free includes 2,000 Actions minutes a month for private repositories.
Price
Team $4 a user a month for the first 12 months
Free plan
Yes: unlimited public and private repositories and 2,000 Actions minutes a month

30. Linear

linear.app

Linear tracks issues, projects and cycles for software teams, with Linear Agent on every plan.

You bring
Bugs, feature requests and the decisions behind them
You get
A prioritized backlog, cycles and projects linked to the code that closed them
Example
Turn a customer’s quote into an issue with the recording linked, put it in this cycle, and let the merged pull request close it.
Shortlist it if
You want one place where the team’s commitments live, apart from chat.
Choose it over
Notion or GitHub Issues when you want triage, cycles and a backlog built for software.
Think twice if
Your backlog will pass 250 issues soon: Free stops there, and Basic costs $10 a user a month.
Price
Basic $10 a user a month billed annually; Business $16
Free plan
Yes: unlimited members, two teams, 250 issues and Linear Agent

31. Notion

notion.com

Notion holds documents, wikis and databases in one workspace, with AI search, writing help and custom agents.

You bring
Specs, decisions, research notes and how-we-work pages
You get
A searchable company memory that outlasts chat threads
Example
Keep a decision log where each entry links the customer evidence and the Linear project it led to.
Shortlist it if
Decisions keep getting lost in chat and you need one place to write them down.
Choose it over
Google Docs when you want documents and simple databases in one place.
Think twice if
You want custom agents to do recurring work: after a free trial they run on credits.
Price
Plus $10 a member a month billed annually, $12 monthly; Business $20 billed annually, $24 monthly
Free plan
Yes, with a block limit once you collaborate and 5 MB uploads
Watch the extra costs
Custom agents run on Notion credits: $10 per 1,000 after a free trial.

32. Slack

slack.com

Slack is team chat with channels, huddles and notifications from the other tools in your stack.

You bring
Team conversations and alerts from GitHub, Sentry, Linear and the rest
You get
Quick coordination, and one place where alerts reach the person who acts on them
Example
Send new Sentry errors to an #alerts channel, and move every decision out of chat into Linear.
Shortlist it if
You have more than two people and alerts from several tools.
Choose it over
Group email or a messaging app once alerts, integrations and searchable history matter.
Think twice if
You rely on old threads: the free plan deletes messages and files after a year.
Price
Pro €8.25 a user a month, or €6.75 billed annually
Free plan
Yes; data older than a year is deleted

33. Google Workspace

workspace.google.com

Google Workspace gives the company its own email addresses, calendars, Drive, Docs and Meet, run from one admin console.

You bring
Your domain and the people who need company accounts
You get
Company-owned email, files and calendars that stay with the business when people leave
Example
Create founder@ and support@ addresses on your domain, and sign up for every tool in this list with a company address.
Shortlist it if
You are about to sign up for the tools on this list: register them to company accounts from day one.
Choose it over
Personal Gmail accounts, because the company should own the logins for billing, domains and code.
Think twice if
Your team already works in Microsoft 365: keep it and skip this line.
Price
Business Starter €6.80 a user a month
Free plan
No; a 14-day trial

Market and automate

Automate a task after you have done it by hand often enough to describe it. Framer gives the marketing site to whoever writes the copy, Buffer keeps social posting on schedule, and Zapier or n8n connects the tools above once a repeated task costs more than the automation would.

34. Framer

framer.com

Framer is a website builder for marketing sites, with a visual editor, CMS, hosting and AI credits.

You bring
Your brand, copy and page designs
You get
A hosted marketing site that a non-engineer can change without a deploy
Example
Ship a launch landing page the same day, without touching the app’s repository.
Shortlist it if
Someone other than the engineers will change the marketing site every week.
Choose it over
Building the marketing site inside your app when design changes should not wait for an engineer.
Think twice if
Your engineers own the site and like it in the repository: keep it in Next.js and skip this cost.
Price
Basic $10 a month, Pro $30 a month, billed yearly; extra editors $20 a month
Free plan
Yes: a Framer domain, 1 GB of bandwidth and 500 AI credits
Watch the extra costs
Localization and A/B testing are paid add-ons.

Posts and the channels you publish to

Shortlist it if
Posting on social is a weekly habit for the founder.
Choose it over
HubSpot’s social tools when scheduling posts is all you need and you want to pay per channel.
Think twice if
You post a few times a month: the free plan covers three channels.
Price
Essentials $5 a channel a month billed yearly; Team $10
Free plan
Yes: three channels, 10 scheduled posts per channel, one user

36. n8n

n8n.io

n8n builds workflows and AI agents from connected nodes, hosted by n8n or on your own server, and bills per workflow run however many steps it has.

You bring
The apps to connect and the logic between them
You get
Automations and agents that run on a schedule, on a webhook or on demand
Example
Every Monday, pull last week’s Stripe cancellations, have a model group the reasons, and post the summary to Slack.
Shortlist it if
A developer will own the automations, or your workflows have many steps.
Choose it over
Zapier when workflows have many steps: n8n counts one execution per run.
Think twice if
Nobody technical will maintain it: Zapier is easier for the rest of the team.
Price
Cloud Starter €20 a month billed annually for 2,500 executions; Pro €50 for 10,000
Free plan
Free self-hosted Community Edition; cloud trial without a card
Watch the extra costs
Self-hosting costs servers and upkeep; AI steps can bill through your model provider.

37. Zapier

zapier.com

Zapier connects thousands of apps with automated workflows, plus Tables, Forms and AI steps, without code.

You bring
A trigger in one app and the actions it should cause in others
You get
Automations anyone on the team can build and change
Example
When a Tally form arrives, create a HubSpot contact and post the details to Slack.
Shortlist it if
Non-technical teammates will build the automations.
Choose it over
n8n when the person building the workflow does not write code.
Think twice if
A workflow runs thousands of times with many steps: Zapier bills by task, so each step adds to the bill.
Price
Professional from $19.99 a month billed annually, $29.99 monthly; Team from $69 billed annually
Free plan
Yes: 100 tasks a month and two-step Zaps

What the stack costs each month

The bill starts at $65 a month for a solo founder and grows by seats, not by the number of tools. Both columns use the default stack and stay inside the free plans where the table says $0. Feedbaq costs nothing while your agent builds and you preview studies, and $49 in a month you collect responses.

Monthly cost of the default startup tech stack, prices checked 7 October 2026

Total$65, or $114 in a month you collect, + fees$261, or $310 in a month you collect, + fees

On Cloudflare Workers instead of Vercel, the solo hosting line drops from $20 to $5, for $50 a month, or $99 in a month you collect. Expect the bill to grow in three places first: Supabase compute and egress as data grows, Vercel or Cloudflare usage as traffic grows, and Resend once you send more than 3,000 emails a month or 100 in a day.

If your product calls an AI model, budget the API on its own line. A Claude or ChatGPT subscription covers your team’s use, not your customers’.

The close calls

Supabase, Neon or Convex?

Start with Supabase. Supabase gives you Postgres, sign-in with social providers and multi-factor auth, and file storage in one project, which is what most small web apps need on day one. Choose Neon when you want plain Postgres billed by use and a database branch for every pull request. Choose Convex when live updates between users are the product, such as a shared board or a multiplayer editor, and the whole team writes TypeScript.

Vercel, Cloudflare, or Railway and Render?

Start on Vercel Pro for a Next.js app. Vercel deploys from GitHub with no setup and gives every pull request a preview link. Move to Cloudflare Workers when running costs matter more than setup time: Workers starts at $5 a month and charges nothing for bandwidth, but Next.js runs through the OpenNext adapter, which has settings you must learn. Add Railway or Render next to either one when you need processes that run for minutes or forever, such as queue workers. Pick Railway for billing by use and Render for a fixed price per instance.

Stripe or Paddle?

Choose Stripe unless sales tax across countries would eat your time. Stripe costs 2.9% + 30¢ per US card charge, plus 0.7% for Billing and 0.5% for Tax, and you stay the seller, which means you register for and file the tax yourself. Paddle costs 5% + 50¢ and becomes the seller of record, so the tax is its job. If you sell to many countries from day one and have no finance help, the extra fee buys back hours every month.

Resend, Brevo or Customer.io?

Use Resend first, and add one of the others only when you send email to people, not from code. Resend sends what your app triggers: sign-in links, receipts and alerts. Add Brevo at $9 a month for newsletters and simple sequences. Choose Customer.io at $100 a month when your product events are reliable and you want journeys that react to what each user does, such as a nudge on day three for a trial user who has not invited a teammate.

n8n or Zapier?

Zapier if the builder does not code, n8n if a developer owns it. Zapier is quicker to learn and connects more apps without setup, but it counts tasks, so long workflows that run often get expensive. n8n counts one execution per run however many steps it has, and you can host it yourself.

Cursor, or Lovable and Replit?

Cursor if anyone on the team can read a diff; Lovable if nobody can. Cursor keeps the product in a repository you own, with agents that work across it. Lovable gets a non-technical founder to a working app the fastest, paid by credits. Replit sits between them: the agent builds, but the code, database and hosting stay visible in one workspace. Whichever you pick, put the first version in front of customers before you add a second build tool.

PostHog surveys, or Feedbaq?

Use Feedbaq for every question that starts with “why”. PostHog surveys pop up inside your product and are free up to 1,500 responses a month, which suits a one-click rating, but a typed one-liner rarely explains a decision. Feedbaq answers the question a rating cannot, such as why trial users stop at setup: people explain by voice or show you on screen, and the AI follows up on what they said. Your agent builds the study for free, and you pay $49 a month while you collect.

Two founder workflows

Each one uses tools from different layers, and each step ends with a decision you can make.

Set up the stack in your first week

  1. Create company accounts in Google Workspace, and register every tool below to a company address.
  2. Start the repository on GitHub, build in Cursor, and deploy to Vercel Pro with Supabase behind it.
  3. Install Sentry and PostHog, and track five events: signup, the first useful action, invite, payment and cancellation.
  4. Connect your agent to Feedbaq for free and have it build the study you will send the first users who stall, so it is ready when they do.
  5. Add Stripe and Resend, and write in Linear the job each tool does. Anything without a job waits.

Find out why trial users do not convert

  1. In PostHog, find the step where trial users stop, and watch five replays of it.
  2. Ask your agent in Cursor, Claude or ChatGPT to build a Feedbaq study for those users, asking them to try the step on screen and say what they expected.
  3. Send the link with Resend or from your own inbox, and ask the agent for the reasons, with the number of people behind each and a link to every quote.
  4. Open three of the links and listen. Write the fix in Linear with the customers’ words in it, ship it, and watch the same step in PostHog.

Questions people ask

What is the best tech stack for a startup in 2026?

For a small web startup: Cursor to write code, GitHub and Linear for code and tasks, Supabase for data and sign-in, Vercel Pro for hosting, Sentry for errors, PostHog for product analytics, Feedbaq to hear from customers, Stripe for payments and Resend for app email. Add a tool only when you can name the job it does.

How much does a lean startup tech stack cost per month?

About $65 a month for a solo founder, plus payment fees: Cursor Pro $20, Supabase Pro $25 and Vercel Pro $20, with GitHub, Linear, PostHog, Resend and Sentry on free plans. Feedbaq is free in your AI agent and costs $49 in a month you collect responses, which makes $114. A team of three pays about $261, or $310 in a month it collects.

Can I host a commercial startup on Vercel’s free Hobby plan?

No. Vercel’s Hobby plan is for personal, non-commercial use only. A startup needs Pro, which costs $20 a month with one deploying seat and $20 of usage credit; extra seats are $20 a month each.

Should I choose Supabase, Neon or Convex?

Start with Supabase: Postgres, sign-in and file storage in one project, free to two projects and $25 a month on Pro. Choose Neon for plain Postgres billed by use with a database branch for every pull request. Choose Convex at $25 a developer a month when live updates between users are the core of the product.

Stripe or Paddle for a SaaS startup?

Stripe by default: 2.9% + 30¢ per US card charge, plus 0.7% for Billing and 0.5% for Tax, and you file sales tax yourself. Paddle costs 5% + 50¢ and acts as merchant of record, so it handles sales tax and VAT. Choose Paddle when you sell in many countries from day one without finance help.

What tool should a startup use to hear from customers?

Feedbaq. Connect it to your AI agent in Cursor, Claude or ChatGPT for free, and the agent becomes your expert researcher: it plans and builds the study, and you preview it at no cost. Collecting responses costs $49 a month. Customers answer by voice or show you the problem on screen, the AI follows up on what each one said, and PostHog shows you whom to ask.

Does a ChatGPT or Claude subscription pay for my app’s AI features?

No. Claude Pro and ChatGPT Plus cost $20 a month and cover your team’s use, including Claude Code and Codex. If your product calls a model, the Anthropic or OpenAI API is billed separately by usage.
