Paul Harman

Engineering Manager, Sainsbury’s Tech

Hydra is so smooth; I probably spent more time removing the old OAuth implementation than I did wiring up Hydra into my app.

Yan Gabriel Minário

CTO, myio

We rely on Ory to be our OAuth provider and it fits perfectly into our infrastructure, is hardened, and aligns with our principles. Ory is a great fit for us.
