About Bolt.new

Bolt.new, built by StackBlitz, generates full-stack web applications from natural-language prompts entirely in the browser, using a multi-model backend spanning Claude, GPT-4o, and Gemini. Unlike frontend-only generators, Bolt scaffolds both UI and backend logic, giving every project a shareable live preview URL and one-click export to GitHub for deployment on Vercel, Netlify, or any platform. It has become a favorite for founders and developers validating ideas quickly, though token costs can climb on complex, multi-session projects, and production-scale work typically means using Bolt to generate a foundation and refining it in a proper IDE afterward.
