Blacksmith

Blacksmith runs your GitHub Actions up to 2x faster at half the cost on a fleet of modern gaming-CPU bare metal, booting ephemeral Firecracker microVMs in under three seconds. It is a drop-in replacement integrated as a GitHub App and selected via runs-on runner tags, with a co-located CI cache, 40x faster Docker layer caching, sticky disks, an observability dashboard, and a Testbox CLI. Blacksmith does not publish a general-purpose public REST API - integration is GitHub-App, YAML runner-tag, and GitHub Actions based.
