Ory Hydra
Certified OAuth2/OIDC server implementing the protocol as a headless, API-driven service that delegates login/consent UI to a separate app. Standout trait is a clean separation between the OAuth2 protocol engine and identity/UI concerns.

⚙ Full Stack
Go binary implementing OAuth2/OIDC flows with pluggable SQL backends (PostgreSQL, MySQL, CockroachDB), fully stateless aside from the database. Requires a separately-built login/consent app since Hydra deliberately ships no UI.
📈 Scaling Analysis
The stateless protocol-engine design scales horizontally very cleanly since all session/consent state lives in the SQL backend. Requiring a hand-built login/consent UI is the main practical friction, not a scalability limitation, and post-ORY-commercial-pivot community support has slowed somewhat.
🚀 Running on Nexlayer
Deploy the hydra pod plus a postgres pod at postgres.pod:5432, along with a small login/consent app pod that Hydra redirects to internally via <podName>.pod:<port>; pull images through mirror.gcr.io. Public-facing URLs (issuer, redirect URIs) must use the browser-facing <% URL %> value, never the internal pod DNS.
