Overview

Bolt is StackBlitz's answer to 'AI writes and runs the app for you.'

Detailed review

The instant preview is the star: unlike Lovable, Bolt runs your app in a full Node environment right in the browser, so integration tests and package installs behave predictably.

Pricing

Free daily tokens; Pro unlocks bigger contexts and private projects.

Who should use it

Hackathon builders
Developers testing frameworks and packages
Rapid client demos

Alternatives

Lovable for managed backends and richer visual editing. Replit AI for long-lived collaborative apps.

Editor's verdict

A strong pick for prototyping — Lovable takes it once you need production polish.
