StackBlitz
In-browser AI full-stack dev environment by StackBlitz
Bolt.new runs a full Node.js environment inside your browser and lets you build, run, edit, and deploy full-stack apps with AI assistance. It executes npm packages, handles build tools, and deploys to a public URL — all without leaving the browser tab. It supports any framework (React, Vue, SvelteKit, Astro, Next.js) and uses Claude Sonnet for code generation. **Step-by-step:** 1) Open bolt.new. 2) Describe what you want to build. 3) Bolt scaffolds and runs the app in-browser in ~30 seconds. 4) Chat to iterate. 5) Click 'Deploy' for a shareable URL. **Best for:** rapid prototyping, hackathons, teaching, trying new frameworks without setup.
