Bolt is an AI-powered web development platform that lets anyone build, edit, and deploy full-stack applications directly from the browser. You describe what you want in plain language, and Bolt generates working code, handles the environment setup, and publishes the finished app.

Bolt is a browser-based AI development platform created by StackBlitz that turns written prompts into working full-stack applications. You type a description of the app you want, and Bolt generates the code, spins up a complete development environment in the browser, and renders a live preview instantly. There is nothing to install and no configuration to wrestle with, since the entire stack runs on WebContainers technology that executes Node.js directly in the browser.

The platform supports popular frameworks like React, Next.js, Vue, Astro, and Svelte, and it goes well beyond generating snippets. Bolt can install packages, run backend servers, connect to databases through integrations like Supabase, and deploy finished projects to Netlify with a single click. When something breaks, you can prompt the AI to fix errors, or dive into the code editor yourself and make manual changes. This mix of conversational building and hands-on editing makes it useful for both non-technical founders and experienced developers who want to skip boilerplate.

Bolt has become one of the standout tools in the vibe coding movement, letting you prototype MVPs, landing pages, internal tools, and even mobile apps through its Expo integration, all in a fraction of the usual time. Pricing is token-based, with a free tier for experimentation and paid plans for heavier usage.

Build, edit, and ship complete web apps from your browser.

Key features

• AI-powered app generation — Bolt transforms natural language prompts into complete, functional applications. You describe the product you have in mind, and the AI writes the frontend, backend, and configuration code within minutes.
• In-browser development environment — Built on StackBlitz’s WebContainers technology, Bolt runs a full Node.js environment inside the browser. There is no local setup, no dependency conflicts, and no waiting for installations to finish.
• Live preview and instant iteration — Every change appears immediately in a live preview pane. You can test your app as it evolves, spot issues early, and requests adjustments through follow-up prompts without leaving the page.
