StarSling vs WarpBuild
WarpBuild provides fast, drop-in GitHub Actions runners (and Docker build features). StarSling is also a drop-in runner replacement, and adds the AI-native layer: agents that analyze workflows and open optimization PRs for caching, installs, parallelization, and test sharding. As with other fast-runner providers, the distinction is fast-runners vs fast-runners-plus-self-driving-optimization.
