Where each one falls short

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

GitLab CI/CD

  • Compute minute quotas for Premium and Ultimate tiers not disclosed in documentation
  • Additional compute minutes beyond quota incur charges; exact pricing not specified

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
