A summary, not legal advice.

WHY IT MATTERS

Even a small calculator or sign-up page often means finding a developer or joining a paid builder. AI Builder is an open-source alternative to Lovable, Replit and v0: describe, edit and publish a site or app from the browser.

BUILD FROM THIS

  • Built on Puter.js, which bundles authentication, storage, database, serverless functions and hosting. A live preview updates as you work; you can ask for changes in chat or click an element in the preview to change just that part, and restore earlier saved versions.

WHO IT'S FOR

Small business owners, planners and students who want a simple site or tool without writing code.

START IN 5 MINUTES

# Open builder.puter.com and type what you want to build, or start from one of the suggested ideas such as a quiz game or an expense tracker.

CAVEATS

  • Apps you make run on Puter.js (Puter's auth, storage and hosting), so they depend on the Puter platform. The repository is new (117 stars).
