I've been using "Cirrus Runners" since that tweet and it has been fantastic. Huge speed increase, huge cost decrease, zero maintenance, exactly what I wanted.

It’s been plain-sailing with the Cirrus Runners — they’ve been great! They’re consistently 60+% faster on workflows that we previously used Github Actions’ macOS runners for.

Previously, we were using the GitHub‑hosted macOS runners and our iOS build took ~30 minutes. Now with Cirrus Runners, the iOS build only takes ~12 minutes. That’s a huge boost to our productivity, and for only $150/month per runner it is much less expensive too.
