Where each one falls short

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

Ory Kratos

  • 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

Traefik

  • No transparent pricing displayed for Traefik Hub API Gateway or API Management products
  • No subscription period specified for paid tiers
  • Traefik Hub products require contacting sales for pricing
