Blacksmith GitHub Actions Runners
Drop-in faster GitHub-hosted runner replacement selected by changing the runs-on tag (e.g. blacksmith-2vcpu-ubuntu-2404). Linux/Windows jobs run in ephemeral Firecracker microVMs; x64, ARM64, and macOS (Apple Silicon M4) families are offered in 2-32 vCPU sizes. Configured via the GitHub App and YAML workflow, not a programmatic REST API.
