One button to commit, push, and make a PR.

Every agent thread writes to its own branch. When it's good, one button opens the PR on GitHub with a generated title, body and changelog. No terminal dance required.

  • Auto-generated PR titles & bodies
  • Inline diff review before you push
  • Draft PRs, stack PRs, amend PRs
  • Works with your existing GitHub auth
Open source

If you don't like something, fork it.

Your agents deserve better than a terminal.

Not Codex is free, open source and early. Review the code, build it locally, and connect the coding-agent subscriptions you already use.
