StarSling
Fast GitHub Actions runners with AI agents that continuously optimize your workflows.
StarSling is an agent-native CI platform for GitHub Actions that provides managed CPU and GPU runners as drop-in replacements for ubuntu-latest and ubuntu-24.04, alongside AI agents that analyze workflows, run logs, and machine telemetry to open pull requests optimizing caching, parallelization, test sharding, and workflow structure. It is designed for software teams running build and test workflows on GitHub Actions, including AI product and developer-tool teams, platform teams managing growing CI usage, and teams running GPU-dependent tests or model evaluations.
The platform offers CPU runners on 5th Gen AMD EPYC hardware in six sizes from 2 to 64 vCPU, plus dedicated NVIDIA GPU runners (RTX PRO 6000, RTX 5090, RTX 4090) billed by the minute. Review Runners let teams run their own code review agents in CI using their model key, repository skills, and scripts. Open-source agent skills (ci-speedup, ci-score, ci-secure) and the sling CLI provide workflow diagnostics. StarSling is packaged with a free trial including 2,000 minutes in the first month, a usage-based plan with per-minute pricing and unlimited concurrency, and an Enterprise edition with volume discounts, custom minute allocation, SSO/SAML, and dedicated support. Continuous CI optimization is included in paid plans; GPU runners and Review Runners are available through request access and early access respectively.
