AI-native GitHub Actions runners with agents that continuously optimize builds, up to 6x faster

starsling.devAbout StarSling
StarSling is self-driving CI: AI-native GitHub Actions runners paired with agents that continuously look at your build and optimize it, with the headline claim being up to 6x faster pipelines. The premise is that most teams never revisit their CI configuration after it is written, so caching is wrong, steps run serially that could run in parallel, and runners are sized for a workload that changed a year ago — all of which is legible to an agent watching every run. Rather than asking a team to rewrite their workflows, StarSling slots in as the runner layer for existing GitHub Actions, so the migration is a configuration change rather than a rebuild, and the same jobs a team already runs — lint, type-check, unit tests, builds, Playwright and Cypress end-to-end suites, Docker builds, security scans, Terraform plans, preview deploys — keep running as written while the optimization happens underneath. The product also ships a ci-speedup skill that installs into a coding agent, which lets developers ask for CI improvements from the same place they already work. Getting started is free with no credit card required, and the company publishes customer references, feature documentation, and guides.
