Hey everyone,

If you run CI workflows for Mac or Linux apps, you know how fast cloud runner costs—especially macOS build minutes—can stack up on platforms like GitHub Actions or GitLab CI. Paying high per-minute rates for cloud build boxes while having powerful, underutilized M-series silicon sitting on your desk doesn't make much sense.

To solve this, I built kinhin ( https://kinhin.dev ). It’s a free, open-source (Apache-2.0), zero-telemetry autoscaler that lets you offload CI builds onto your Apple Silicon Mac cleanly and safely.

How It Works:

* Queue-Driven Autoscaling: kinhin monitors your forge's job queue and spins up ephemeral runners on demand.

* Isolated Runtimes: Runs macOS jobs in Tart VMs and Linux jobs in Apple microVMs or Docker containers.…
