Amazing piece of (high quality) software! If you're spending more than 100$/month on github actions or just want faster builds in general, you should give this a try. I was amazed how easy it was to setup (just need an AWS account and 30 minutes). Founder is also very responsive to feature requests and suggestions. We're in the process of replacing our k8s based ARC Runner with runs-on.com, hoping to reduce maintenance burden and CI cost by thousands of $ month.
