Bolt is an AI-powered full-stack web development platform created by StackBlitz that enables users to prompt, run, edit, and deploy web applications directly in the browser. Using advanced AI models, Bolt can generate complete web applications from natural language descriptions, handling frontend and backend code, package installation, database configuration, and deployment in a single integrated environment. Unlike traditional AI code generators that only produce code snippets, Bolt operates within a WebContainer environment that runs a full Node.js runtime in the browser, allowing it to install npm packages, run development servers, execute build processes, and handle complex project configurations without any local setup or cloud VM. Users interact with Bolt through a chat-based interface where they describe the application they want to build or the changes they want to make. Bolt generates the complete project structure, writes the code, resolves errors, and presents a live preview of the running application. The iterative workflow allows users to refine their applications through follow-up prompts, making it accessible to both experienced developers looking to accelerate development and non-technical users building their first web applications. Bolt supports popular frameworks including React, Next.js, Vue, Svelte, Astro, and others, and can work with databases, authentication systems, and third-party APIs. The platform offers a free tier with limited daily tokens, and paid plans starting at $20 per month for increased token allowances, faster model access, and deployment features. Applications built with Bolt can be deployed directly to production through integrated hosting.
