StarSling vs Blacksmith
Blacksmith provides fast, drop-in GitHub Actions runners on better hardware. StarSling is also a drop-in runner replacement, and adds the AI-native layer: agents that analyze your workflows, logs, and telemetry and open pull requests that optimize caching, installs, parallelization, and test sharding. The category difference is fast-runners vs fast-runners-plus-self-driving-optimization.
