Bolt.new by StackBlitz is an AI agent that can build full-stack web applications from natural language prompts. It runs entirely in the browser using WebContainers technology, meaning it can install npm packages, run Node.js servers, and execute code without any local setup. Users describe what they want, and Bolt generates the complete application including frontend, backend, database schema, and deployment configuration.
Bolt.new represents a new paradigm in software development: describe what you want to build, and an AI agent creates it for you. Powered by StackBlitz’s WebContainers technology, Bolt runs a complete development environment in your browser, including Node.js, npm, and a development server. This means you go from idea to working application in minutes, with no local setup required.
What makes Bolt.new special is that it does not just generate code — it executes it. The AI writes your application code, installs dependencies, starts the development server, and shows you the running result. If something does not work, it can see the error messages and fix them iteratively. It supports modern frameworks like React, Next.js, Vue, Svelte, and Astro, and can set up databases, authentication, and API integrations.
Bolt.new is ideal for rapid prototyping, hackathon projects, and building MVPs. Non-technical founders use it to create working demos. Developers use it to scaffold new projects quickly. It is also excellent for learning, as you can see how a working application is structured while building it conversationally.
