| Free tier | no free hosted compute beyond a trial: the FOSS plan is free with your own workers, hosted workers are billed at USD 0.33 an hour even on it, and new users get a 14-day trial on the demo system, after which builds stop. The demo needs no signup and builds the newest 3 commits of a repository unit none; metered on none; the hosted plan is USD 37 a month per developer plus USD 0.33 per worker-hour; a developer is a person who pushes at least 3 commits to private repositories in a month |
|---|---|
| Price | none stated |
| Limits |
the demo runs only the newest 3 commits of a repository |
| Binding | volume-quota hosted compute is paid by the second on every plan and the only free hosted use is the 14-day trial, so no free hosted allowance remains after it |
| Identity | email sign-in is through a GitHub, GitLab or Codeberg account, and NixCI stores the email address from that account; the demo needs no signup or payment details; a paid plan is billed through Stripe; whether the FOSS plan asks for a card is unverified: behind a sign-up |
| Egress | not stated |
| Per-object cap | unverified: the hosted worker and pricing pages state no per-job time limit |
| Retention | build logs are kept 60 days; build metadata 90 days; cached artefacts 90 days (60 days) |
| Interface | git a GitHub App, a GitLab or a Codeberg webhook runs CI for every repository that has a flake.nix, with no in-repo configuration required; results come back as commit statuses |
| Tooling | a flake.nix in the repository; the NixCI GitHub App, or a GitLab or Codeberg integration; hosted workers are 16 vCPU, 64 GiB RAM, 1 TB disk, x86_64-linux machines at Hetzner |
| Composes with | the hosted workers run x86_64-linux Nix builds, tests and deployments from a flake; a GitHub Actions job on a public repository comes first, and the user's own workers come last |
| Reliability | unverified: the vendor publishes no uptime figure or status page that was read |
| Notes | A hosted Nix CI exists with no free hosted allowance: the FOSS plan is free only when the user supplies the workers, and hosted worker time is paid by the second, so the offer is trial-only. Hosted runners of this topic come first. Last resort: the user's own workers, which NixCI offers to any subscriber on request. |
| Evidence note | documented every value is quoted from the vendor's pricing, workers, demo, getting-started and privacy pages; no sign-up was made, so the terms of the FOSS plan, the card requirement and any per-job time cap are unverified |
