Bolt.new

Bolt.new by StackBlitz is a browser-based AI tool that generates and runs complete full-stack web applications from natural language prompts. Unlike code completion tools that help you write code line by line, Bolt.new creates entire projects with frontend, backend, database schemas, and API routes in a single prompt.

It runs everything inside WebContainers, StackBlitz's browser-based runtime technology, meaning no local environment setup is needed. You can see your application running live as Bolt generates it, make changes through conversation, and deploy directly to production.

The tool handles popular stacks including React, Next.js, Vue, Svelte, Express, and more, automatically managing package dependencies, configuration files, and project structure. Bolt.new is particularly powerful for MVPs, proof-of-concepts, and internal tools where getting something working quickly matters more than architecture perfection.

The AI can iterate on its own output, fixing errors, adding features, and refactoring code based on your feedback in real time. For developers, it eliminates the tedious project setup phase entirely. For non-technical founders, it provides a way to build functional prototypes without hiring a developer.

The free tier includes limited daily token usage, while paid plans unlock more generous limits and advanced features.
