ORY Hydra is a hardened, OpenID Certified OAuth 2.0 Server and OpenID Connect Provider optimized for low-latency, high throughput, and low resource consumption. ORY Hydra is not an identity provider (user sign up, user login, password reset flow), but connects to your existing identity provider through a login and consent app. Implementing the login and consent app in a different language is easy, and exemplary consent apps (Go, Node) and SDKs are provided.

What is ORY Hydra?
ORY Hydra is a server implementation of the OAuth 2.0 authorization framework and the OpenID Connect Core 1.0. Existing OAuth2 implementations usually ship as libraries or SDKs such as node-oauth2-server or fosite, or as fully featured identity solutions with user management and user interfaces, such as Dex.
Implementing and using OAuth2 without understanding the whole specification is challenging and prone to errors, even when SDKs are being used. The primary goal of ORY Hydra is to make OAuth 2.0 and OpenID Connect 1.0 better accessible.
ORY Hydra implements the flows described in OAuth2 and OpenID Connect 1.0 without forcing you to use a "Hydra User Management" or some template engine or a predefined front-end. Instead it relies on HTTP redirection and cryptographic methods to verify user consent allowing you to use ORY Hydra with any authentication endpoint, be it authboss, User Frosting or your proprietary Java authentication.
Who's using it?
The ORY community stands on the shoulders of individuals, companies, and maintainers. We thank everyone involved - from submitting bug reports and feature requests to contributing patches to sponsoring our work. Our community is 1000+ strong and growing rapidly. The ORY stack protects 1.200.000.000+ API requests every month with over 15.000+ active service nodes. Our small but expert team would have never been able to achieve this without each and every one of you.

OAuth2 and OpenID Connect: Open Standards!
ORY Hydra implements Open Standards set by the IETF:
- The OAuth 2.0 Authorization Framework
- OAuth 2.0 Threat Model and Security Considerations
- OAuth 2.0 Token Revocation
- OAuth 2.0 Token Introspection
- OAuth 2.0 for Native Apps
- Proof Key for Code Exchange by OAuth Public Clients
and the OpenID Foundation:
- OpenID Connect Core 1.0
- OpenID Connect Discovery 1.0
- OpenID Connect Dynamic Client Registration 1.0
- OpenID Connect Front-Channel Logout 1.0
- OpenID Connect Back-Channel Logout 1.0
OpenID Connect Certified
ORY Hydra is an OpenID Foundation certified OpenID Provider (OP).
The following OpenID profiles are certified:
- Basic OpenID Provider (response types
- Implicit OpenID Provider (response types
- Hybrid OpenID Provider (response types
- OpenID Provider Publishing Configuration Information
- Dynamic OpenID Provider
To obtain certification, we deployed the reference user login and consent app (unmodified) and ORY Hydra v1.0.0.
This section is a quickstart guide to working with ORY Hydra. In-depth docs are available as well:
5 minutes tutorial: Run your very own OAuth2 environment
Head over to the ORY Developer Documentation to learn how to install ORY Hydra on Linux, macOS, Windows, and Docker and how to build ORY Hydra from source.
ORY Security Console: Administrative User Interface
The ORY Security Console is a visual admin interface for managing ORY Hydra, ORY Oathkeeper, and ORY Keto.
ORY Oathkeeper: Identity & Access Proxy
ORY Oathkeeper is a BeyondCorp/Zero Trust Identity & Access Proxy (IAP) built on top of OAuth2 and ORY Hydra.
ORY Keto: Access Control Policies as a Server
ORY Keto is a policy decision point. It uses a set of access control policies, similar to AWS IAM Policies, in order to determine whether a subject (user, application, service, car, ...) is authorized to perform a certain action on a resource.
The ory/examples repository contains numerous examples of setting up this project individually and together with other services from the ORY Ecosystem.
Why should I use ORY Hydra? It's not that hard to implement two OAuth2 endpoints and there are numerous SDKs out there!
OAuth2 and OAuth2 related specifications are over 400 written pages. Implementing OAuth2 is easy, getting it right is hard. ORY Hydra is trusted by companies all around the world, has a vibrant community and faces millions of requests in production each day. Of course, we also compiled a security guide with more details on cryptography and security concepts. Read the security guide now.
If you think you found a security vulnerability, please refrain from posting it publicly on the forums, the chat, or GitHub and send us an email to email@example.com instead.
Our continuous integration runs a collection of benchmarks against ORY Hydra. You can find the results here.

Upgrading and Changelog
Command line documentation
hydra -h or
Developing with ORY Hydra is as easy as:
go get -d -u github.com/ory/hydra cd $GOPATH/src/github.com/ory/hydra make init export GO111MODULE=on ## With database make test ## Without database make quicktest
Then run it with in-memory database:
DSN=memory go run main.go serve all
- We changed organization name from
ory. In order to keep backward compatibility, we did not rename Go packages.
- You can ignore warnings similar to
package github.com/ory/hydra/cmd/server: case-insensitive import collision: "github.com/sirupsen/logrus" and "github.com/sirupsen/logrus".
