description: >-
  FinOps view of Trunk platform spend. Trunk bills per committer, with Flaky
  Tests usage measured in test spans (1M test spans per committer included on
  Free and Team). The Free plan covers up to 5 committers at no cost; Team is
  free to start with custom pricing at scale; Enterprise is custom-priced with
  volume discounts on test spans. Code Quality CLI usage and the Merge Queue
  are seat-based features rather than per-call metered APIs.
notes: >-
  Per-committer and at-scale pricing are subject to change; verify against the
  trunk.io/pricing page during reconciliation. Test spans are the primary
  usage driver - reducing flaky-test churn and pruning low-value test runs
  lowers span consumption.
