Five levels of CI optimization, from the Actions cache to swapping runners, tuning workflows, switching CI engines, and replacing CI with agents.

A $3M pre-seed from Bessemer Venture Partners, Y Combinator and five more funds to make shipping code agent-native, and Review Runners in private beta.

GitHub Actions runners backed by NVIDIA GPUs: RTX PRO 6000, RTX 5090 and RTX 4090, with H100 coming. One line in runs-on. Contact us to get started.

The job was green. The logs were clean. CI Harness v2 found the 11-month-old bottleneck anyway, and made that job 5.4x faster.
sling is the agent-first CLI for StarSling Runners. Diagnose a failed job, rank your slowest workflows, see CI costs, and read only the log lines that matter.

Sixteen GitHub Actions optimization recipes with runnable YAML, tradeoffs, and verify steps, plus one JSON file your coding agent fetches to find the right one.

Eighteen free GitHub Actions best practices guides with copyable YAML, verify steps, and markdown mirrors your coding agent can read and apply to your repo.
Scan your GitHub Actions for the ten critical CI/CD attack vectors. ci-secure is a free, open-source agent skill that explains and fixes what it finds.

Our sandbox benchmarks now have an interactive results explorer and a refreshed run covering 11 environments. Pick any metric and percentile, share the view.
