Quoted from the docs introduction: 'Run jobs on your own cloud - bring AWS, GCP, Azure, Hetzner, DigitalOcean, Oracle, OpenStack, or Vast.ai credentials' and 'Pay your cloud, not the runner provider'. unit unlimited; metered on wall-clock; free-orchestration-only |

| Identity | card no payment instrument to Cirun: the Open Source plan is 'Always free for open source' at USD 0. The card sits one layer down, because the runners execute in a cloud account the caller already holds: the setup docs require 'a Service Account with Compute Engine Admin Permissions' and a downloaded JSON key pair, i.e. an existing billed AWS, GCP, Azure, Hetzner, DigitalOcean, Oracle, OpenStack or Vast.ai identity. The authorisation amount is not stated, and whether those clouds accept debit or prepaid is not stated |

| Composes with | The composition it enables is real and is the reason to keep the row: Cirun plus an Oracle Always Free Ampere instance would put that instance's cores behind a GitHub Actions label, so a free cloud can be addressed as a CI runner. The constraint is that the free tier it composes with must already exist. |

| Notes | Verdict is paid-only rather than qualifies, and the distinction matters: 'free for open source' here means free to schedule, and a reader who takes it for free GPU capacity will find a Vast.ai invoice. It is a strong chain member and a zero on its own. The docs FAQ and getting-started paths both 404, so the pricing page and the docs index are the evidence; docs.cirun.io returned 200 for both. |
