Ory Hydra is an OpenID Certified OAuth 2.0 and OpenID Connect provider server written in Go, handling token issuance, client management, and login/consent orchestration via headless APIs. It integrates with any existing identity system and can be self-hosted or consumed as a managed service on the Ory Network.
Use cases
- issue OAuth2 access tokens for my APIs
- add OpenID Connect single sign-on to my apps
- self-host an OIDC provider that works with my existing user database
- implement machine-to-machine client credentials flows
- federate login with social providers via OIDC
- secure microservices with OAuth2 token validation
- run a certified OAuth2 server at high scale
When to choose
- you need a hardened, OpenID Certified OAuth2/OIDC provider
- you want full control over login and consent UI while delegating identity to your own system
- you need low-latency, high-throughput token issuance
- you want to self-host or use a managed cloud IAM service
When to avoid
- you need a full identity management solution with registration, login UI, and MFA out of the box (use Ory Kratos instead)
- you want a simple all-in-one auth library embedded in your app
- you need SAML as a first-class protocol
