  • They diverge on capability: Doppler covers Secrets 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.

Doppler

  • Developer tier limited to 3 free users with per-user fees beyond that
  • Team plan pricing ($21/user/mo) adds cost for large teams
  • 90-day activity log retention may be insufficient for long-term audits
  • Enterprise plan requires custom pricing conversation

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
