Semaphore's team open-sourced SuperPlane, a factory that turns backlog issues into review-ready PRs
superplanehq/superplane is at 6,166 stars, 629 forks and a near-even 322 open PRs to 284 open issues, Apache 2.0, built by the Semaphore CI team and still labeled beta. It picks high-confidence backlog issues and drives them to verified, review-ready pull requests, framing itself as an 'open source factory for one-shot engineering' rather than a chat-driven coding agent. The selection step matters more than the generation step here: it decides which issues are safe to attempt unattended, which is the gate most autonomous-PR tools skip.
