Hydra
Add OpenID Connect and OAuth 2.1 identity-provider capabilities through Ory Hydra’s headless APIs.
About Hydra
Ory Hydra is an open source server that implements the OAuth 2.0 authorization framework and OpenID Connect Core 1.0. The homepage describes it as OpenID Certified and written in Go. It handles OAuth 2.0 and OpenID Connect flows, token issuance and validation, client management, consent and login flow orchestration, and JWKS management.
Hydra does not include user management. It is designed to connect to an existing identity provider through a login and consent app, which gives the operator control over the user interface and login flows. The homepage lists Ory Kratos, authboss, and User Frosting as examples of compatible authentication endpoints, along with proprietary systems. It can be self-hosted or consumed as a service on Ory Network.
