Zendesk Engineering Team
Cirrus Runners provide a remarkable speed increase with their M4 Pro runners, significantly reducing build times. They offer a cost-effective solution that enhances productivity while minimizing expenses. In addition to these benefits, we experienced no downtime throughout the past year, making the service very reliable. Highly recommended!

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.
Truecaller Engineering Team
Before transitioning to Cirrus Runners, managing our in-house Macs felt like an uphill battle. We had to deal with macOS updates, keep up with Xcode updates, and juggle iOS simulators. Thankfully, those days are behind us! Now, we simply request the macOS and Xcode versions we need, and everything operates seamlessly on the powerful M4 Pro. This upgrade has not only eliminated our worries but also boosted our efficiency, slashing build times by 50%.

One of the finest one-line changes we ever made. Our workflows required no other adjustments, builds and especially test runs are faster across the board, the monthly bill is lower, and technical support is fast & knowledgable. I wish we had known about Cirrus Runners earlier!
Artem Dorosh
Senior Mobile Engineer at Cuvva
Our transition to Cirrus Runners surpassed all expectations. You get the latest-gen Apple Silicon performance and faster GitHub Actions Cache at a very competitive price point per runner. Our test and build times were reduced by half compared to the previous provider, enabling the seamless migration of our CI infrastructure to GitHub Actions. Additionally, the ability to test locally with Tart images before committing to the service provided invaluable flexibility.

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.
