The short version

  • Each has a real cost: CKAN the package install path requires Ubuntu 20.04 or 22.04 64-bit specifically; other operating systems must use the source install; Ory Kratos headless means you build every screen, which is significant work compared with a hosted login page
  • They diverge on capability: CKAN covers Dataset Management, Ory Kratos covers Headless API.

Where each one falls short

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

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

Ory Kratos

  • Headless means you build every screen, which is significant work compared with a hosted login page
  • More moving parts than a monolithic IAM: Kratos handles identity, and OAuth2 needs Ory Hydra alongside
  • Documentation assumes real familiarity with identity concepts and is not a gentle introduction
  • Self-hosting identity carries the security and availability burden that hosted providers absorb
