Where each one falls short

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

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult
