What is Blacksmith CI?
Blacksmith CI is a drop-in replacement for GitHub Actions runners, designed to significantly speed up CI/CD pipelines and reduce costs. It achieves this by running jobs on high-performance bare metal gaming CPUs, offering faster cache downloads through co-located artifacts, and accelerating Docker builds by persisting layers on NVMe drives. The platform aims to cut build, test, and deploy times in half, providing immediate feedback on pull requests.
Beyond performance, Blacksmith CI addresses the observability gap in GitHub Actions. It provides a console for quickly seeing what's happening in CI pipelines, helping developers spot failing and slow jobs, debug flaky tests, and fix issues directly from GitHub comments with inline logs. This makes it ideal for development teams looking to optimize their CI/CD workflows, improve developer productivity, and reduce infrastructure spending, especially those heavily reliant on GitHub Actions.
