Blacksmith (blacksmith.sh) provides managed GitHub Actions runners that are designed to be significantly faster and more cost-effective than standard GitHub-hosted runners. Their platform utilizes high-performance gaming CPUs and a highly optimized software stack specifically tailored for continuous integration (CI), offering features such as zero cold startup times, advanced caching for all runtimes, and shared layer caches for Docker builds. These optimizations help engineering teams accelerate their CI pipelines and minimize time spent managing infrastructure, so they can focus on their core business challenges.
Organizations using Blacksmith also benefit from built-in analytics tools that provide visibility into the health and efficiency of their CI workflows. This allows teams to monitor, troubleshoot, and optimize their pipelines with actionable data.
