Bolt.diy is an AI-powered web development agent that allows you to prompt, run, edit, and deploy full-stack web applications directly from your browser, with no local setup required. It integrates cutting-edge AI models with an in-browser development environment powered by StackBlitz’s WebContainers, enabling you to install and run npm tools and libraries, run Node.js servers, interact with third-party APIs, and deploy to production from chat. Unlike traditional development environments where AI can only assist in code generation, Bolt.diy gives AI models complete control over the entire environment, including the filesystem, node server, package manager, terminal, and browser console, empowering AI agents to handle the entire app lifecycle, from creation to deployment. Whether you’re an experienced developer, a PM, or a designer, Bolt.diy allows you to build production-grade full-stack applications with ease.
