The Vibe Coding Tech Stack
On this page
Tech stack choice has always mattered. With AI writing most of the code, it matters in a different way: some stacks work much better with AI than others. The difference shows up in how often the code is right the first time and how much of your day you spend on manual setup.
In this article, we'll cover the stack that works best for vibe coding, from the tools you write with to how you ship.
Vibe Coding Tools
Vibe coding is the term Andrej Karpathy gave to the way many people now write software with AI: you describe what you want, the model writes it, you accept the suggestions, run them, and iterate. "Forget that the code even exists" was the line.
Several tools support this workflow. Pick one before the rest of the stack, because it shapes how you work with everything else.
Claude Code is Anthropic's agentic coding tool. Primarily terminal-based, but also available as a desktop app on macOS and Windows and as an IDE plugin. You give it a task, it edits files across your project, runs commands, and reports back. Strongest for multi-file changes, refactors, and anything that touches more than the file in front of you. For most non-trivial vibe coding, this is the default to reach for.
Cursor is a fork of VS Code with AI built into the editor. Best-in-class tab completion, multi-file edits via Composer, agent mode with Plan Mode and Checkpoints, and background agents for running tasks in parallel. The right choice if you want to stay in an IDE with a visual diff workflow.
Codex is OpenAI's agentic coding tool, comparable to Claude Code in scope. Available as a CLI, a desktop app, IDE plugins, and a web interface inside ChatGPT. The natural choice if you prefer OpenAI's models or already pay for ChatGPT.
Which one you pick mostly boils down to preference. Claude tends to top the coding benchmarks, and Claude Code is the most popular pick for vibe coding, so the rest of this article assumes it as the primary tool. The advice transfers cleanly to the others.
Frontend
The frontend choice mostly comes down to training data and convention stability.
AI models are pattern-matchers. They produce better code when the patterns are well-represented in their training data and when those patterns don't change every six months. Three choices follow from this:
Next.js with React. Massive training data, opinionated conventions, mature ecosystem. The App Router has been stable enough for long enough that the AI handles it reliably. Vite plus React is the other reasonable pick if you don't need server-side rendering.
TypeScript over JavaScript. Types give the AI more context about your code. When the AI knows that a function expects a User, it makes fewer mistakes about what to pass in. The cost (slightly more verbose code) is paid back many times over in correctness.
Tailwind CSS. Utility classes are pattern-heavy in a way that suits language models. The AI rarely guesses wrong about which class to use, and the styles end up consistent across components without much effort on your part. Other CSS approaches work, but Tailwind has the lowest friction.
Avoid bleeding-edge frameworks for vibe coding. If the framework had a major API change in the last year, the AI will mix old and new patterns and you'll spend time correcting it.
Backend
The frontend is where AI shines. The backend is where vibe coding tends to stall.
Most modern apps need the same handful of things on the server side: a database, file storage, authentication, and increasingly an AI API. Each of these is well-documented enough that AI can write the integration code. The problem is everything around the integration: provisioning the database, setting up the auth provider, copying secrets into env files, deploying a server, wiring those services together. The AI can produce the code for each piece, but it can't reliably do the setup work between them, and it can't see when a connection string is wrong or a webhook isn't firing.
For a typical app, this plumbing eats most of the build time. You drop out of vibe coding flow to do DevOps the AI can't help with.
Puter.js is one way to remove that friction. It's a JavaScript library that gives you backend services (auth, database, file storage, and AI APIs) through a single object you call from your frontend code. There is no server to deploy and no environment to configure. You import the script, and the AI has one API surface to work with instead of four or five.
A few examples of what the AI will write when you tell it to use Puter.js:
// auth
await puter.auth.signIn()
const user = await puter.auth.getUser()
// database
await puter.kv.set('preferences', { theme: 'dark' })
const prefs = await puter.kv.get('preferences')
// file storage
await puter.fs.write('notes/today.md', content)
// AI
const reply = await puter.ai.chat('Summarize this:', text)
For many apps, that is the entire backend surface area.
The part worth understanding before you commit to this stack is how the storage and compute get paid for. Your users sign in with a Puter account, and their data lives in their Puter storage. The AI calls run against their AI credits. Two things follow from this:
- Your infrastructure cost stays flat as your app grows. Whether you have ten users or ten thousand, you aren't paying for their storage or their model calls.
- Your users need a Puter account, or need to create one through your signup flow. You'll need to decide if this model fits your app. It works well for consumer apps and indie SaaS. For internal tools, or apps where you want to own the user data end to end, a traditional backend is the more natural choice.
Puter.js can also be used server-side, but the User-Pays Model only applies when calls come from the client, where the signed-in user's account is the one authorizing the request. From a server, you'd be authorizing against your own account and the cost advantage would disappear.
The practical effect for vibe coding is that your prompts get shorter and your AI gets more accurate. Instead of telling it to provision a database, generate types, wire up middleware, and store secrets, you tell it to use Puter.js for auth, storage, and AI calls. The AI already knows the API. There is no setup for it to get wrong.
Authentication
Auth is one of the most painful parts of any web app to set up by hand, and one of the parts where AI is least helpful with the setup even though it can write the code fine.
Clerk has the cleanest developer experience and the best React integration. Drop-in components for sign-in, sign-up, and user profiles. Pricing scales with monthly active users.
Supabase Auth comes free if you're already using Supabase for the database. Less polished UI primitives than Clerk, but one fewer vendor.
NextAuth (Auth.js) is the open-source option. You host it, you configure it, you keep it running. Cheaper at scale, more work to set up.
If you're using Puter.js, auth is included. puter.auth.signIn() gives you a signed-in user without configuring a provider, setting up callback URLs, or storing secrets. The same account flows through to the rest of the Puter.js APIs, which is what makes the User-Pays Model work end to end.
Payments
Stripe is the standard. The AI knows it well, the documentation is extensive, and the integration code is well-trodden ground.
The caveat is that AI is least reliable on the parts of payment code that matter most: webhook signature verification, idempotency keys, currency math, refund logic. The integration code looks correct and runs locally, then fails in production in ways that are expensive to debug. Review payment-related code carefully and write tests for it even if you skip tests elsewhere.
Lemon Squeezy is worth considering if you're a solo dev who doesn't want to deal with sales tax, VAT, or merchant-of-record paperwork. The tradeoff is higher fees.
Deployment
Vercel is the obvious deployment target for Next.js. Push to a connected GitHub repo, get a preview URL on every branch, ship to production on merge. The free tier handles real traffic.
Netlify and Cloudflare Pages are roughly equivalent for static and frontend-only apps. Netlify's free tier is generous; Cloudflare's edge network is faster globally.
Railway and Fly.io are the options if you do need a long-running server somewhere.
If your backend is Puter.js, you only need to host the static frontend. Any of the above works.
Design and Planning
Plan before you code. Write a short document covering what you're building, the data model, and the main flows, and hand it to the AI as part of the initial prompt. Skipping this step is the most common failure mode of vibe coding: you describe a feature in pieces, the AI overcorrects across turns, and an hour later you've burned context on something you could have specified in a paragraph.
Use AI design tools like v0, Lovable, or Bolt for UI mockups you can pass as reference. Set up design tokens (colors, spacing, typography) in your Tailwind config at the start so the AI uses them consistently.
Testing
TypeScript on save, lint, and deployment previews catch most of what AI gets wrong. Ask the AI to write tests for anything you can't visually verify. Heavy test suites are usually overkill for solo or small-team apps until you have real users depending on them.
Version Control
Use git, commit after every working change rather than at the end of a session. AI tools sometimes break things subtly across edits, and the cheapest fix is git reset to the last commit that worked. GitHub for hosting.
Cost
There are three rough cost shapes to choose from.
Traditional self-hosted infrastructure. Predictable, grows with users. You provision database, server, and storage, and pay for them whether they're used or not. Cheapest at scale, most setup work.
Serverless and managed services. Pay per use. Cheap or free at zero usage, scales with traffic. Easy to get started, can spike if you go viral or hit an inefficiency. Vercel, Supabase, AWS Lambda fall in this category.
User-Pays. Users authenticate with their own account on the platform you're built on, and their storage and compute draw from their quota, not yours. Puter.js is the main option here. Your infrastructure cost stays flat regardless of how many users you have.
The first two are well understood. The third is worth flagging because it changes the economics of development meaningfully. An app that would cost several hundred dollars a month at ten thousand users costs nothing on a User-Pays Model. It might not fit every product, but for the ones it does, it removes one of the cost pressures small apps usually hit as they grow.
The Prompt Template
A reusable starting prompt is the single highest-leverage thing in a vibe coding workflow. Copy this, adjust the project description, and use it as the system prompt or first message in any new project.
## Project
[One-line description of what you're building.]
## Stack
- Next.js 16 with App Router
- TypeScript
- Tailwind CSS
- Puter.js for backend (read https://docs.puter.com/llms.txt)
- Deployed to Vercel
## Conventions
- Use server components by default; client components only when needed for interactivity
- All data access through Puter.js:
- Auth: puter.auth.signIn() / puter.auth.getUser()
- Key-value database: puter.kv.set() / puter.kv.get()
- File storage: puter.fs.write() / puter.fs.read()
- AI: puter.ai.chat()
- Tailwind for all styling; no separate CSS files
- Strict TypeScript; no `any` types unless explicitly justified
- Prefer composition over abstraction; keep components small
## What to build
[Describe the feature or app to build.]
## Don't
- Don't add new dependencies without asking
- Don't suggest setting up a separate backend, BaaS, or auth provider. This project uses Puter.js for all of it
- Don't refactor unrelated code
- Don't write tests unless explicitly asked
The Don't section keeps the AI from suggesting conventional backends out of habit.
Conclusion
The recommended vibe coding tech stack: Claude Code as the AI, Next.js with TypeScript and Tailwind on the frontend, Puter.js for backend (auth, database, file storage, AI calls), Stripe for payments, Vercel for deployment, and Git and GitHub for version control. Each piece is well-known to the AI, well-documented for humans, and minimal in setup.
The Puter.js layer is what removes the largest source of vibe coding friction: the gap between writing code and having a working backend. And the User-Pays Model means the cost structure doesn't punish you for shipping something that catches on.
