Bolt.new

About Bolt.new

Bolt.new is a browser-based development environment built by StackBlitz that lets users create, edit, and deploy full-stack web applications using natural language prompts. The tool combines an AI coding assistant with a live runtime environment, meaning users can describe what they want to build and watch functional code appear, run, and update in real time without leaving the browser. It supports npm packages, meaning the full Node.js ecosystem is available, and it handles both frontend and backend code within the same interface. The primary use cases include rapid prototyping, building side projects, and scaffolding applications that would otherwise require significant setup time. A developer can describe a full-stack app — a to-do list, a dashboard, a REST API with a connected frontend — and Bolt.new generates working code that runs immediately. Users can then edit that code directly in the browser editor, prompt further changes through the AI interface, or do both simultaneously. Deployment is built into the workflow, so pushing a project live does not require switching to a separate service or configuring external infrastructure. Bolt.new is aimed at developers who want to move quickly, including experienced engineers who want to skip boilerplate and beginners who can use AI assistance to bridge knowledge gaps. It is particularly useful for solo builders, hackathon participants, and anyone evaluating an idea without wanting to invest in full local environment setup. The tool operates on a credit-based usage model tied to AI interactions, with a free tier available and paid plans that offer higher usage limits. Because the entire environment runs in the browser via WebContainers technology, there is no local installation required, which lowers the barrier to entry considerably. The tradeoff is that complex, large-scale production applications may eventually outgrow what a browser-based environment can comfortably support.
