About Bolt

Bolt (bolt.new) is a revolutionary in-browser AI-powered web development platform created by StackBlitz. Powered by WebContainers technology, Bolt enables developers, designers, and creators to prompt, build, run, debug, and deploy complete full-stack web applications entirely inside modern web browsers with zero local environment setup.

Unlike traditional AI coding tools that only generate isolated code snippets, Bolt runs a full Node.js server runtime directly inside the browser tab. Users can describe complex applications using natural language, and Bolt's AI will scaffold projects, install npm packages, create backend API endpoints, write frontend components in React or Vue, and execute the live application in a real-time side-by-side preview.

Bolt allows developers to inspect generated source code, make manual code edits, run terminal commands, and deploy finished web applications directly to Netlify in a single click. It offers a free tier with daily AI token allowances alongside Pro and Team subscription tiers with higher token limits and private project hosting.
