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

CKAN

  • The package install path requires Ubuntu 20.04 or 22.04 64-bit specifically; other operating systems must use the source install
  • Only Solr 9 and Solr 8 are supported, and from CKAN 2.10 they are the only Solr versions supported at all
  • A working deployment requires PostgreSQL, Solr, Redis, nginx, supervisor and uWSGI to be installed and maintained separately
  • Python 3.10 or later is required
