The short version

  • Only GitHub Actions has a free tier, so it costs nothing to try first.
  • Each has a real cost: GitHub Actions private repository usage is capped at 2,000 minutes per month on GitHub Free and 3,000 on Pro and Team, with anything beyond billed; WarpBuild per-minute pricing requires tracking usage to estimate monthly costs

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GitHub Actions

  • Private repository usage is capped at 2,000 minutes per month on GitHub Free and 3,000 on Pro and Team, with anything beyond billed
  • Artifact storage is only 500 MB on GitHub Free and 2 GB on Team, and it is shared with GitHub Packages storage
  • Larger runners are always charged for, even on public repositories and even when plan quota remains
  • Windows runners cost $0.010 per minute against $0.006 for a 2-core Linux runner, so the same workflow costs more per platform
  • macOS runners are charged at a higher per-minute rate than Linux runners
  • Failed runs consume minutes, so a job that fails after 5 minutes and is re-run for 10 uses 15 minutes of quota
  • Storage is billed on hourly accrual in GB-Hours, so deleting artifacts stops future charges but does not remove charges already accrued in the cycle
  • Cache storage is a separate 10 GB per repository allowance and peak hourly usage above it is charged
  • Minutes are charged to the repository owner, not the person who triggered the run, and anyone with write access can trigger runs
  • Without a valid payment method on file, workflows are blocked as soon as the quota is exhausted

WarpBuild

  • Per-minute pricing requires tracking usage to estimate monthly costs
  • Large configuration runners (32 vCPU) expensive at $0.064/min
  • macOS M4 Pro 12-core at $0.16/min is highest-cost option
  • BYOC option requires cloud setup by customer
