Bolt.new is pure AI-driven development — describe what you want and it builds it. Replit is a full cloud IDE with AI assistance where you can also write code manually. Bolt is faster; Replit is more flexible.
Both run in the browser. Bolt is more AI-driven; Replit is more of a traditional IDE.
AI Full-Stack Builder
Describe an entire app and Bolt builds it — frontend, backend, and database — all in your browser. Preview and deploy without leaving the tab.
Ideal for: Beginners who want a working full-stack app as fast as possible, without setting up a development environment.
AI Browser IDE
Write, run, and deploy code entirely in your browser. Built-in AI assistant helps you build, and everything runs on Replit's cloud — no installation needed.
Ideal for: Students, beginners, and anyone who wants to start building immediately without installing anything.
