  • 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

More detail

  • 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.
