Work in Open Source, Ory is hiring!
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 (Node) and SDKs for all common languages are provided.
If you're looking to jump straight into it, go ahead:

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 Keycloak.
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.

OpenID Connect Certified
ORY Hydra is an OpenID Foundation certified OpenID Provider (OP).
The following OpenID profiles are certified:
- Basic OpenID Provider (response types
code) - Implicit OpenID Provider (response types
id_token,id_token+token) - Hybrid OpenID Provider (response types
code+id_token,code+id_token+token,code+token) - 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.
Quickstart
This section is a starter guide to working with ORY Hydra. In-depth docs are available as well:
5 minutes tutorial: Run your very own OAuth2 environment
The tutorial teaches you to set up ORY Hydra, a Postgres instance and an exemplary identity provider written in React using docker-compose. It will take you about 5 minutes to complete the tutorial.
Installation
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.
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. Gives absolute control over 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.
Security
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.

Upgrading and Changelog
New releases might introduce breaking changes. To help you identify and incorporate those changes, we document these changes in UPGRADE.md and CHANGELOG.md.
Command line documentation
Run hydra -h or hydra help.
Develop
We encourage all contributions and encourage you to read our contribution guidelines.
Dependencies
You need Go 1.13+ with GO111MODULE=on and (for the test suites):
- Docker and Docker Compose
- Makefile
- NodeJS / npm
It is possible to develop ORY Hydra on Windows, but please be aware that all guides assume a Unix shell like bash or zsh.
Formatting Code
You can format all code using make format. Our CI checks if your code is properly formatted.
Running Tests
There are three types of tests you can run:
- Short tests (do not require a SQL database like PostgreSQL)
- Regular tests (do require PostgreSQL, MySQL, CockroachDB)
- End to end tests (do require databases and will use a test browser)
All of the above tests can be run using the makefile. See the commands below.
Makefile commands
# quick tests
make quicktest
# regular tests
make test
test-resetdb
# end-to-end tests
make e2eShort Tests
It is recommended to use the make file to run your tests using make quicktest
, however, you can still use the go test command.
Please note:
All tests run against a sqlite in-memory database,
thus it is required to use the -tags sqlite build tag.
Short tests run fairly quickly. You can either test all of the code at once:
go test -v -failfast -short -tags sqlite ./...or test just a specific module:
go test -v -failfast -short -tags sqlite ./clientor a specific test:
go test -v -failfast -short -tags sqlite -run ^TestName$ ./...Regular Tests
Regular tests require a database set up. Our test suite is able to work with docker directly (using ory/dockertest) but we encourage to use the Makefile instead. Using dockertest can bloat the number of Docker Images on your system and are quite slow. Instead we recommend doing:
make testPlease be aware that make test recreates the databases every time you run make test. This can be annoying if
you are trying to fix something very specific and need the database tests all the time. In that case we
suggest that you initialize the databases with:
make resetdb
export TEST_DATABASE_MYSQL='mysql://root:secret@(127.0.0.1:3444)/mysql?parseTime=true&multiStatements=true'
export TEST_DATABASE_POSTGRESQL='postgres://postgres:[email protected]:3445/postgres?sslmode=disable'
export TEST_DATABASE_COCKROACHDB='cockroach://[email protected]:3446/defaultdb?sslmode=disable'Then you can run go test as often as you'd like:
go test -p 1 ./...
# or in a module:
cd client; go test .E2E Tests
The E2E tests use Cypress to run full browser tests. You can execute these tests with:
make e2e
The runner will not show the Browser window, as it runs in the CI Mode (background). That makes debugging these type of tests very difficult, but thankfully you can run the e2e test in the browser which helps with debugging! Just run:
./test/e2e/circle-ci.bash memory --watch
# Or for the JSON Web Token Access Token strategy:
# ./test/e2e/circle-ci.bash memory-jwt --watchor if you would like to test one of the databases:
make resetdb
export TEST_DATABASE_MYSQL='mysql://root:secret@(127.0.0.1:3444)/mysql?parseTime=true&multiStatements=true'
export TEST_DATABASE_POSTGRESQL='postgres://postgres:[email protected]:3445/postgres?sslmode=disable'
export TEST_DATABASE_COCKROACHDB='cockroach://[email protected]:3446/defaultdb?sslmode=disable'
# You can test against each individual database:
./test/e2e/circle-ci.bash postgres --watch
./test/e2e/circle-ci.bash memory --watch
./test/e2e/circle-ci.bash mysql --watch
# ...Once you run the script, a Cypress window will appear. Hit the button "Run all Specs"!
The code for these tests is located in ./cypress/integration and ./cypress/support and ./cypress/helpers. The website you're seeing is located in ./test/e2e/oauth2-client.
OpenID Connect Conformity Tests
To run ORY Hydra against the OpenID Connect conformity suite, run
$ test/conformity/start.sh --buildand then in a separate shell
$ test/conformity/test.shRunning these tests will take a significant amount of time which is why they are not part of the CircleCI pipeline.
Build Docker
You can build a development Docker Image using:
make dockerRun the Docker Compose quickstarts
If you wish to check your code changes against any of the docker-compose quickstart files, run:
make docker
docker compose -f quickstart.yml up # ....Libraries and third-party projects
