Continue to About ↓- What it does
- StarSling provides managed CPU and GPU runners that replace GitHub-hosted Ubuntu runners in existing GitHub Actions workflows, plus AI agents that analyze workflow runs and open pull requests proposing CI optimizations such as caching, test sharding and parallelization.
More detail
- It also offers an early-access Review Runners product for running your own code-review agents inside CI.
- It is a GitHub Actions runner alternative, not a full CI/CD platform replacement.
- Best for
- Software, platform and AI developer-tool teams running build, test or GPU jobs on GitHub Actions who want faster runs, less billed queue time and per-minute pricing without seat fees.
More detail
- Also relevant to teams whose PR and CI volume is growing faster than their pipeline keeps up.
- Pricing
- Per-minute, usage-based pricing in USD.
More detail
- CPU runners: 2 vCPU/8 GB $0.004/min, 4 vCPU/16 GB (default) $0.008/min, 8 vCPU/32 GB $0.016, 16 vCPU/64 GB $0.032, 32 vCPU/128 GB $0.064, 64 vCPU/256 GB $0.128
- custom sizes are quoted by sales.
- GPU runners include 4 vCPU/16 GB/100 GB disk: RTX PRO 6000 $0.059
- Main limitation
- Teams that need Windows or macOS runners, a complete CI/CD platform independent of GitHub, or a self-hosted or air-gapped setup
More detail
- supported jobs are Ubuntu 26.04/24.04 on GitHub Actions only.
- Also a poor fit if you expect the optimization agents to work automatically on a free trial — they are paid-plan only and off by default.

About
- StarSling provides managed CPU and GPU runners that replace GitHub-hosted Ubuntu runners in existing GitHub Actions workflows, plus AI agents that analyze workflow runs and open pull requests proposing CI optimizations such as caching, test sharding and parallelization.
- It also offers an early-access Review Runners product for running your own code-review agents inside CI.
- It is a GitHub Actions runner alternative, not a full CI/CD platform replacement.
What it helps with
- GitHub-hosted runners run on older shared hardware, so builds and tests spend time waiting on CPU.
- Queue time before a job starts can consume a large share of a team's CI day.
- Workflow waste goes unfixed because engineers have more pressing product work: caches that miss, serial steps, unsharded
- GPU-dependent tests borrow capacity that is meant for production.
- Rising PR volume from coding agents increases CI cost and queue times.
- Code review becomes a bottleneck as pull request volume grows.
