List prices for private repositories, before free minutes or credits on any side, cheapest first at 5,000 minutes. Public repositories run free on GitHub-hosted standard runners and on Buildhound. Runner sizes differ, as each note says, and a bigger runner may finish the same work in fewer minutes, so a row is the price of the same minutes, not of the same work. One machine runs these minutes a job at a time. Personal is for a personal account, Team for an organisation.
Choose the one that fits
Stay with StarSling when
- You want agents that read your runs and open pull requests to shard tests, fix caching and right-size jobs.
- You need GPU runners, or Linux machines up to 64 vCPU.
- Your CI is Linux only and nobody on the team has a machine to spare.
A machine you already have fits when
- Your CI includes macOS, which StarSling does not run.
- Your Linux CI runs past about 2,500 minutes a month.
- You want GitHub-hosted kept as the fallback when a machine is offline.
