A browser-based AI app builder that turns a plain-English description into a running full-stack web application — database, backend, and UI generated together in minutes.
What Is Bolt.new?
Bolt.new is a browser-based AI app builder by StackBlitz. You describe a web application in plain English and Bolt generates, runs, and iterates on the full stack — frontend, backend, and dependencies — entirely in-browser without any local setup. It supports React, Vue, Node.js, and common frameworks, and can deploy to production with a single click.
Bolt.new vs Replit: Which Should You Use?
Bolt.new is optimized for rapid prototyping — you get a running app from a prompt in under a minute. Replit adds collaborative coding, persistent cloud VMs, deployment infrastructure, and an AI agent that can work inside existing projects. Bolt is the fastest path from idea to demo; Replit is the better choice when you need a persistent development environment or team collaboration beyond a single session.
