Watch ads. Get an app.

Use a frontier model for free. The ads pay for it.

Describe an app or a change. The agent compiles it while 30-second ads play. The ads pay for the model tokens, so the build is free. You get a preview or diff, and you can download the result. Sign in when you want to work on a repository or push a new app.

Beta: The builder is free with ads, and our goal is to offer a coding agent cheaper than anyone.
