The short version

  • Each has a real cost: Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature; 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

Where each one falls short

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

Asyncapi

  • Complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
  • Keeping AsyncAPI documents up to date is challenging as systems evolve
  • Tracing and debugging asynchronous operations is more difficult than synchronous request-response patterns

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
