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. It connects to your existing identity provider through a login and
consent app, giving you absolute control over the user interface and experience.
What is Ory Hydra?
Ory Hydra is a server implementation of the OAuth 2.0 authorization framework
and the OpenID Connect Core 1.0. It follows
cloud architecture best practices
and focuses on:
- OAuth 2.0 and OpenID Connect flows
- Token issuance and validation
- Client management
- Consent and login flow orchestration
- JWKS management
- Low latency and high throughput
We recommend starting with the
Ory Hydra introduction docs to learn more
about its architecture, feature set, and how it compares to other systems.
Why Ory Hydra
Ory Hydra is designed to:
- Be a standalone OAuth 2.0 and OpenID Connect server without user management
- Connect to any existing identity provider through a login and consent app
- Give you absolute control over the user interface and experience flows
- Work with any authentication endpoint:
Ory Kratos,
authboss,
User Frosting, or your proprietary system
- Scale to large numbers of clients and tokens
- Fit into modern cloud native environments such as Kubernetes and managed
platforms
OAuth2 and OpenID Connect: Open Standards
Ory Hydra implements Open Standards set by the IETF:
and the OpenID Foundation:
OpenID Connect Certified
Ory Hydra is an OpenID Foundation
certified OpenID Provider (OP).
The following OpenID profiles are certified:
To obtain certification, we deployed the
reference user login and consent app
(unmodified) and Ory Hydra v1.0.0.
Deployment options
You can run Ory Hydra in two main ways:
- As a managed service on the Ory Network
- As a self hosted service under your own control, with or without the Ory
Enterprise License
Use Ory Hydra on the Ory Network
The Ory Network is the fastest way to use Ory
services in production. Ory OAuth2 & OpenID Connect is powered by the open
source Ory Hydra server and is API compatible.
The Ory Network provides:
- OAuth2 and OpenID Connect for single sign on, API access, and machine to
machine authorization
- Identity and credential management that scales to billions of users and
devices
- Registration, login, and account management flows for passkeys, biometrics,
social login, SSO, and multi factor authentication
- Prebuilt login, registration, and account management pages and components
- Low latency permission checks based on the Zanzibar model with the Ory
Permission Language
- GDPR friendly storage with data locality and compliance in mind
- Web based Ory Console and Ory CLI for administration and operations
- Cloud native APIs compatible with the open source servers
- Fair, usage based pricing

Self-host Ory Hydra
You can run Ory Hydra yourself for full control over infrastructure, deployment,
and customization.
The install guide explains how to:
- Install Hydra on Linux, macOS, Windows, and Docker
- Configure databases such as PostgreSQL, MySQL, and CockroachDB
- Deploy to Kubernetes and other orchestration systems
- Build Hydra from source
This guide uses the open source distribution to get you started without license
requirements. It is a great fit for individuals, researchers, hackers, and
companies that want to experiment, prototype, or run unimportant workloads
without SLAs. You get the full core engine, and you are free to inspect, extend,
and build it from source.
If you run Hydra as part of a business-critical system, for example OAuth2 and
OpenID Connect for all your users, you should use a commercial agreement to
reduce operational and security risk. The Ory Enterprise License (OEL)
layers on top of self-hosted Hydra and provides:
- Additional enterprise features that are not available in the open source
version
- Regular security releases, including CVE patches, with service level
agreements
- Support for advanced scaling, multi-tenancy, and complex deployments
- Premium support options with SLAs, direct access to engineers, and onboarding
help
- Access to a private Docker registry with frequent and vetted, up-to-date
enterprise builds
For guaranteed CVE fixes, current enterprise builds, advanced features, and
support in production, you need a valid
Ory Enterprise License and access
to the Ory Enterprise Docker registry. To learn more,
contact the Ory team.
Quickstart
Install the Ory CLI and
create a new project to try Ory OAuth2 & OpenID Connect.
# Install the Ory CLI if you do not have it yet:
bash <(curl https://raw.githubusercontent.com/ory/meta/master/install.sh) -b . ory
sudo mv ./ory /usr/local/bin/
# Sign in or sign up
ory auth
# Create a new project
ory create project --create-workspace "Ory Open Source" --name "GitHub Quickstart" --use-project
Try out the OAuth 2.0 Client Credentials flow:
ory create oauth2-client \
--name "Client Credentials Demo" \
--grant-type client_credentials
# Note the client ID and secret from output
ory perform client-credentials \
--client-id <your-client-id> \
--client-secret <your-client-secret>
# Note the access token from output
ory introspect token <your-access-token>
Try out the OAuth 2.0 Authorize Code + OpenID Connect flow:
ory create oauth2-client \
--name "Authorize Code with OpenID Connect Demo" \
--grant-type authorization_code,refresh_token \
--response-type code \
--redirect-uri http://127.0.0.1:4446/callback
ory perform authorization-code \
--client-id <your-client-id> \
--client-secret <your-client-secret>

Ecosystem
We build Ory on several guiding principles when it comes to our architecture
design:
- Minimal dependencies
- Runs everywhere
- Scales without effort
- Minimize room for human and network errors
Ory's architecture is designed to run best on a Container Orchestration system
such as Kubernetes, CloudFoundry, OpenShift, and similar projects. Binaries are
small (5-15MB) and available for all popular processor types (ARM, AMD64, i386)
and operating systems (FreeBSD, Linux, macOS, Windows) without system
dependencies (Java, Node, Ruby, libxml, ...).
Ory Kratos: Identity and User Infrastructure and Management
Ory Kratos is an API-first Identity and User
Management system that is built according to
cloud architecture best practices.
It implements core use cases that almost every software application needs to
deal with: Self-service Login and Registration, Multi-Factor Authentication
(MFA/2FA), Account Recovery and Verification, Profile, and Account Management.
Ory Hydra: OAuth2 & OpenID Connect Server
Ory Hydra is an OpenID Certified™ OAuth2 and
OpenID Connect Provider which easily connects to any existing identity system by
writing a tiny "bridge" application. It gives absolute control over the user
interface and user experience flows.
Ory Oathkeeper: Identity & Access Proxy
Ory Oathkeeper is a BeyondCorp/Zero Trust
Identity & Access Proxy (IAP) with configurable authentication, authorization,
and request mutation rules for your web services: Authenticate JWT, Access
Tokens, API Keys, mTLS; Check if the contained subject is allowed to perform the
request; Encode resulting content into custom headers (X-User-ID), JSON Web
Tokens and more!
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.
