Product Demo

CI is the new bottleneck

AI made coding 10x faster. CI hasn't kept up, until now.

AI in your CI

StarSling Runners are faster, smarter, and cheaper.

Faster Builds

Self-driving

AI agents deep-scan your workflow runs and ship optimization PRs

  • Dependency installation — implement faster install strategies (e.g., frozen lockfiles, parallel installs)
  • Build steps — parallelize, remove redundant and optimize slow steps
  • Tests — detect misconfigured test jobs and test database interactions
  • Workflow structure — implement job splitting, matrix strategies, and dependency ordering

Cheaper Than GitHub

4 vCPU Linux runners with 16 GB RAM at usage-based pricing

  • $0.008/min vs GitHub's $0.012/min (33% cheaper)
  • Queue time never billed
  • AI optimizations included
