Where each one falls short

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

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

Moonrepo

  • Smaller community compared to established build systems like Bazel
  • Limited integrations with enterprise CI/CD platforms
  • Documentation gaps in some advanced use cases
  • No commercial support option for organizations requiring guaranteed SLAs
