Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Blacksmith
- Per-minute pricing model requires estimating usage to predict costs
- macOS M4 pricing ($0.08/min) is significantly higher than GitHub Actions
- Docker layer caching and sticky disks are paid add-ons at $0.50/GB/mo
- Static IP add-on costs $100/IP/mo
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
