Ory
Open source identity, authorization and zero trust stack (Kratos, Hydra, Keto, Oathkeeper) available self-hosted or as Ory Network SaaS.
Quick answer
What is Ory?
Short answer
Ory is an open source identity and authorization ecosystem made up of several focused components: Kratos for identity, Hydra for OAuth2 / OIDC, Keto for authorization (Google Zanzibar-inspired) and Oathkeeper for zero trust access. Teams can self-host the open source stack or use Ory Network, the managed SaaS. It tends to appeal to engineering-heavy teams that want composable identity primitives rather than a packaged CIAM product.
