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
- 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.
- 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.
- 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.
- 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.
| Layer | Default | Cost at the start | Switch or add only when |
|---|---|---|---|
| Write code | Cursor | $20/mo | Nobody on the team writes code: start in Lovable |
| Code and tasks | GitHub, Linear | $0 | Linear passes 250 issues: Basic is $10 a user |
| Data and sign-in | Supabase | $0, then $25/mo at launch | The app is live and collaborative: Convex |
| Hosting | Vercel | $20/mo (Hobby is non-commercial) | You need long-running workers: add Railway |
| Errors | Sentry | $0 for one user | A second developer joins: Team is $26/mo |
| Product analytics | PostHog | $0 up to 1M events | Measurement drives most decisions: Amplitude |
| Hear from customers | Feedbaq | Free in your AI agent; $49/mo while you collect | Never skip it: add Tally only for waitlist and intake forms |
| Payments | Stripe | 2.9% + 30¢ per charge | You sell in many countries and want tax handled: Paddle |
| App email | Resend | $0 up to 3,000/mo | Product events should trigger journeys: Customer.io |

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.comCursor 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.comAnthropic’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.comOpenAI’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.devLovable 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.comReplit 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.comFigma 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.comSupabase 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.comNeon 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.devConvex 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.comClerk 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.comVercel 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.comCloudflare 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.comRailway 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.comRender 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.ioSentry 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.toMade 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

- Price
- Plus starts at $0 and scales with event volume beyond 2M; Growth and Enterprise on request

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

- 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

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.

- 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.

- You bring
- Your brand, copy and page designs
- You get

- Choose it over
- Zapier when workflows have many steps: n8n counts one execution per run.

- Price
- Cloud Starter €20 a month billed annually for 2,500 executions; Pro €50 for 10,000
- Free plan

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.
| Service | Solo founder | Team of three | What changes |
|---|---|---|---|
| Cursor | $20 | $120 | Pro for one; Teams at $40 a user |
| Supabase | $25 | $25 | One Pro project; not billed per teammate |
| Vercel | $20 | $60 | Pro includes one seat; extra seats $20 each |
| Sentry | $0 | $26 | Developer is one user; Team billed annually |
| Linear | $0 | $30 | Free to 250 issues; Basic $10 a user, annual |
| GitHub, PostHog, Resend | $0 | $0 | Inside the free plans |
| Feedbaq | $0, or $49 | $0, or $49 | Free in your AI agent; $49 in a month you collect responses |
| Stripe | 2.9% + 30¢ a charge | 2.9% + 30¢ a charge | Paddle instead: 5% + 50¢ |
| 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
- Create company accounts in Google Workspace, and register every tool below to a company address.
- Start the repository on GitHub, build in Cursor, and deploy to Vercel Pro with Supabase behind it.
- Install Sentry and PostHog, and track five events: signup, the first useful action, invite, payment and cancellation.
- 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.
- 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
- In PostHog, find the step where trial users stop, and watch five replays of it.
- 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.
- 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.
- 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.
