Bolt (bolt.new) is an AI full-stack app builder by StackBlitz. You describe what you want to build in plain English, and Bolt generates a complete working application — frontend, backend, database configuration — running live in a browser-based WebContainer environment. Unlike v0 (frontend only) or Replit (cloud VM), Bolt runs your app directly in the browser using WebAssembly, with no server required.
Yes. Bolt has one of the most generous free tiers among AI app builders:
| Plan | Price | Monthly tokens |
|---|---|---|
| Free | $0 | 1M tokens/month (~150K/day) |
| Pro | $20/month | 10M tokens, rollover |
| Teams | $30/user/month | Shared pool, collaboration features |
| Enterprise | Custom | Custom limits, SSO, dedicated support |
1 million tokens per month is substantially more than competitors offer for free. For comparison, v0's free tier gives $5 in credits, and Replit Starter gives limited daily credits. Bolt's free tier is enough to build and test small-to-medium projects without paying anything.
WebContainer runs a Node.js-compatible environment entirely inside your browser using WebAssembly. Your code executes locally in the browser tab — not on a remote server. This means near-instant startup, offline capability once loaded, and no cloud compute costs that get passed on to you. The trade-off is that WebContainer has some limitations with native binaries and certain Node.js packages that require native compilation.
React, Next.js, Astro, Vue, Svelte, SvelteKit, Remix, Vite, and plain HTML/CSS/JS. It also supports Node.js backends with Express, Fastify, and similar frameworks. The full-stack capability is Bolt's main differentiator over v0, which is React/Next.js only.
Both are browser-based AI app builders. The main differences:
| Bolt | Replit | |
|---|---|---|
| Execution | Browser WebContainer | Cloud VM |
| Free tier | 1M tokens/month | Limited daily credits |
| Offline | Partial (after load) | No |
| Framework support | Node.js ecosystem | 50+ languages |
| Deployment | Via Netlify/Vercel export | Replit hosting built-in |
| Agent pricing | Token-based | Effort-based (can be unpredictable) |
Bolt's token-based pricing is more predictable than Replit's effort-based billing. Replit handles more languages and has built-in hosting; Bolt runs faster in-browser but requires exporting to deploy.
v0 generates frontend React components; Bolt generates full-stack applications including backend APIs and database setup. If you need a landing page or UI components, v0 is faster and more polished for that specific use case. If you need a working full-stack app with a Node.js backend, Bolt is the better fit. Both tools are complementary: some developers use v0 for UI and Bolt for the API layer.
On the free plan, Bolt stops generating when you hit the daily limit (approximately 150K tokens/day). The monthly 1M token limit resets on your billing date. On Pro, unused tokens roll over to the next month — up to 2× the monthly allocation. On all plans, you can purchase additional tokens when needed.
Bolt generates production-quality code that you can export to GitHub and deploy to Netlify, Vercel, or any hosting platform. However, for complex applications with custom authentication, intricate database schemas, or heavy backend logic, Bolt's generated code often needs review and refinement by a developer. It excels at getting to a working prototype fast; production hardening usually requires manual work.
