  • They diverge on capability: Ory Kratos covers Headless API, Vagrant covers Box management.

Where each one falls short

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

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

Vagrant

  • Vagrant 2.4.3 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Vagrant to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vagrant
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published
  • Uses that fall outside the Additional Use Grant require a separately negotiated licence from the licensor
