One keyEvery model

The AI software engineer for your desktop.

Optamus Code reads your repos, writes the code, runs the tests in a sandbox, verifies in a real browser, and opens the pull request. It runs on the Optamus API — one key that routes to gpt-4o, claude-3-5-sonnet, and every model in between.
