## NixCI

- `ci-cd-runners/nixci` | trial-only | evidence documented | binding volume-quota | category CI runner | tier FOSS
- needs card unknown, phone no, ID no, institution no | verified 2026-11-02T15:23:42.915Z (live) | stale on 2026-12-03
- url https://nix-ci.com/pricing
- 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 | read on: 2026-11-02 | source: [1] | note: 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
- per-object cap: unverified: the hosted worker and pricing pages state no per-job time limit | source: [2]
- retention: build logs are kept 60 days; build metadata 90 days; cached artefacts 90 days | days: 60 | source: [3]
- egress: not stated | metered: no | source: [1]
- identity: email | detail: 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
- interface: git
- limits:
  - volume-quota (binding): 14-day trial on the demo system; builds stop after it ends unless the account is upgraded [1]
  - volume-quota (binding): hosted workers billed at USD 0.3342 an hour per second of job execution, on every plan [2]
  - retention-clamped: build logs 60 days; build metadata and cached artefacts 90 days [3]
- limits note: the demo runs only the newest 3 commits of a repository
- binding note: 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
- interface detail: 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: 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
- self hosted: no
