Bolt.new

Bolt.new is StackBlitz’s AI app builder, and its unique technical advantage is that it runs a full Node.js environment directly in your browser — meaning you can build, test, and deploy a complete web application without installing anything locally.

The free tier gives limited daily tokens. Starter ($20/mo) gives 10 million tokens/month. Pro ($50/mo) gives 50 million tokens and larger project support.

Type a description of what you want to build, and Bolt generates a working React or Next.js app with a real database (Supabase integration), authentication, and full code you can see and edit. The in-browser preview updates in real time as the AI makes changes. When you’re ready, deploy to Netlify or Cloudflare in one click.

Bolt handles the complete stack: frontend components, backend API routes, database schema, and environment variables. Its browser-based execution model means every generated app is a real, running application — not a mockup. Bolt’s rapid growth alongside Lovable has helped establish “vibe coding” as a mainstream category.

Pros: Runs entirely in browser (no local setup), real-time execution, Supabase and Netlify integration, React/Next.js output, good for MVPs.
Cons: Token limits can be hit on complex apps, less mature than Cursor for experienced developers, occasional context loss on large projects.

Best for: Non-developers building MVPs, developers prototyping quickly, entrepreneurs validating ideas, and students learning full-stack development.
