Bolt is an AI-powered full-stack web application builder by StackBlitz that generates, runs, and deploys complete apps directly in the browser from a single text prompt. Unlike other AI coding tools, Bolt executes real Node.js environments in WebAssembly, meaning there is nothing to install — just describe what you want to build and Bolt produces a working app with frontend, backend, and database wired together. It supports React, Next.js, Svelte, and dozens of other frameworks, making it the fastest path from idea to deployed web application.
