Bolt.new

Bolt.new is the AI app builder by StackBlitz, the inventors of WebContainer (a full Node.js environment that runs in your browser). Describe your app in natural language, Bolt generates the code, runs it live in the tab, and deploys it to Netlify in one click.

The technical differentiator: no remote cloud. Everything runs inside your browser tab — npm install, bundler, dev server — which removes latency and infra costs. You can fork an existing project or start from a template (Next.js, Astro, Vite, SvelteKit).

Bolt is used for fast prototyping, client demos, and increasingly for production-ready MVPs.
