Bolt.new is an open-source, browser-based AI agent that enables users to prompt, build, and deploy full-stack web applications by orchestrating the entire development lifecycle within a StackBlitz environment.

Try it out

In-browser AI app builder by StackBlitz that scaffolds full-stack apps.

Bolt.new leverages the power of StackBlitz‘s WebContainer technology to provide a sandbox where an AI agent can write code, run terminal commands, and fix bugs in real-time. Unlike simple code snippet generators, it scaffolds entire full-stack architectures, handles package installations, and provides an instant live preview of the application. It integrates directly with the Anthropic Claude 3.5 Sonnet model to interpret natural language instructions, allowing users to iterate on UI components and backend logic through a conversational interface while maintaining a persistent file structure.

Pros

  • Provides a seamless 'one-click' deployment path to Netlify, enabling users to move from an initial prompt to a live production URL in minutes.
  • Allows users to fix errors by simply pasting terminal bug reports back into the chat, which the AI then analyzes to apply automatic patches.
  • Leverages Next.js and Vite templates to ensure all generated applications follow modern web development best practices and high-performance standards.

Cons

  • The in-browser WebContainer approach may experience performance bottlenecks or memory limitations when compiling exceptionally large enterprise-level Node.js projects.
  • Initial project scaffolding can occasionally include unnecessary boilerplate files that require manual cleanup to optimize the final application bundle size.
  • Advanced backend features like persistent SQL databases or complex server-side cron jobs often require external integration beyond the instant frontend preview.
