Tart already powers several CI services mentioned above including our own Cirrus CI which offers unlimited concurrency with per-second billing. For services that haven't leveraged Tart yet, we offer fully managed runners via a monthly subscription. Cirrus Runners is the fastest way to get your current CI workflows to benefit from Apple Silicon hardware. No need to manage infrastructure or migrate to another CI provider.
Testimonials from customers¶
Sebastian Jachec, Mobile Engineer at Daybridge.
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.
Max Lapides, Senior Mobile Engineer at Tonal.
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.
