Ory Hydra _is not_ an identity provider (user sign up, user login,\npassword reset flow), but connects to your existing identity provider through a\n[login and consent app](https://www.ory.sh/docs/hydra/oauth2#authenticating-users-and-requesting-consent).\nImplementing the login and consent app in a different language is easy, and\nexemplary consent apps ([Node](https://github.com/ory/hydra-login-consent-node))\nand [SDKs](https://www.ory.sh/docs/kratos/sdk/index) for common languages are\nprovided.\n\nOry Hydra can use [Ory Kratos](https://github.com/ory/kratos) as its identity\nserver.\n\n## Ory Hydra on the Ory Network\n\nThe [Ory Network](https://www.ory.sh/cloud) is the fastest, most secure and\nworry-free way to use Ory's Services. **Ory OAuth2 \u0026 OpenID Connect** is powered\nby the Ory Hydra open source federation server, and it's fully API-compatible.\n\nThe Ory Network provides the infrastructure for modern end-to-end security:\n\n- Identity \u0026 credential management scaling to billions of users and devices\n- Registration, Login and Account management flows for passkey, biometric,\n  social, SSO and multi-factor authentication\n- **Pre-built login, registration and account management pages and components**\n- **OAuth2 and OpenID provider for single sign on, API access and\n  machine-to-machine authorization**\n- Low-latency permission checks based on Google's Zanzibar model and with\n  built-in support for the Ory Permission Language\n\nIt's fully managed, highly available, developer \u0026 compliance-friendly!\n\n- GDPR-friendly secure storage with data locality\n- Cloud-native APIs, compatible with Ory's Open Source servers\n- Comprehensive admin tools with the web-based Ory Console and the Ory Command\n  Line Interface (CLI)\n- Extensive documentation, straightforward examples and easy-to-follow guides\n- Fair, usage-based [pricing](https://www.ory.sh/pricing)\n\nSign up for a\n[**free developer account**](https://console.ory.sh/registration?utm_source=github\u0026utm_medium=banner\u0026utm_campaign=kratos-readme)\ntoday!\n\n## Ory Network Hybrid Support Plan\n\nOry offers a support plan for Ory Network Hybrid, including Ory on private cloud\ndeployments. If you have a self-hosted solution and would like help, consider a\nsupport plan! The team at Ory has years of experience in cloud computing. Ory's\noffering is the only official program for qualified support from the\nmaintainers. For more information see the\n**[website](https://www.ory.sh/support/)** or\n**[book a meeting](https://www.ory.sh/contact/)**!\n\n## Get Started\n\nYou can use\n[Docker to run Ory Hydra locally](https://www.ory.sh/docs/hydra/5min-tutorial)\nor use the Ory CLI to try out Ory Hydra:\n\n```shell\n# This example works best in Bash\nbash \u003c(curl https://raw.githubusercontent.com/ory/meta/master/install.sh) -b . ory\nsudo mv ./ory /usr/local/bin/\n\n# Or with Homebrew installed\nbrew install ory/tap/cli\n```\n\ncreate a new project (you may also use\n[Docker](https://www.ory.sh/docs/hydra/5min-tutorial))\n\n```\nory create project --name \"Ory Hydra 2.0 Example\"\nproject_id=\"{set to the id from output}\"\n```\n\nand follow the quick \u0026 easy steps below.\n\n### OAuth 2.0 Client Credentials / Machine-to-Machine\n\nCreate an OAuth 2.0 Client, and run the OAuth 2.0 Client Credentials flow:\n\n```shell\nory create oauth2-client --project $project_id \\\n    --name \"Client Credentials Demo\" \\\n    --grant-type client_credentials\nclient_id=\"{set to client id from output}\"\nclient_secret=\"{set to client secret from output}\"\n\nory perform client-credentials --client-id=$client_id --client-secret=$client_secret --project $project_id\naccess_token=\"{set to access token from output}\"\n\nory introspect token $access_token --project $project_id\n```\n\n### OAuth 2.0 Authorize Code + OpenID Connect\n\nTry out the OAuth 2.0 Authorize Code grant right away!\n\nBy accepting permissions `openid` and `offline_access` at the consent screen,\nOry refreshes and OpenID Connect ID token,\n\n```shell\nory create oauth2-client --project $project_id \\\n    --name \"Authorize Code with OpenID Connect Demo\" \\\n    --grant-type authorization_code,refresh_token \\\n    --response-type code \\\n    --redirect-uri http://127.0.0.1:4446/callback\ncode_client_id=\"{set to client id from output}\"\ncode_client_secret=\"{set to client secret from output}\"\n\nory perform authorization-code \\\n    --project $project_id \\\n    --client-id $code_client_id \\\n    --client-secret $code_client_secret\ncode_access_token=\"{set to access token from output}\"\n\nory introspect token $code_access_token --project $project_id\n```\n\n---\n\n\u003c!-- START doctoc generated TOC please keep comment here to allow auto update --\u003e\n\u003c!-- DON'T EDIT THIS SECTION, INSTEAD RE-RUN doctoc TO UPDATE --\u003e\n\n- [What is Ory Hydra?](#what-is-ory-hydra)\n  - [Who's using it?](#whos-using-it)\n  - [OAuth2 and OpenID Connect: Open Standards!](#oauth2-and-openid-connect-open-standards)\n  - [OpenID Connect Certified](#openid-connect-certified)\n- [Quickstart](#quickstart)\n  - [Installation](#installation)\n- [Ecosystem](#ecosystem)\n  - [Ory Kratos: Identity and User Infrastructure and Management](#ory-kratos-identity-and-user-infrastructure-and-management)\n  - [Ory Hydra: OAuth2 \u0026 OpenID Connect Server](#ory-hydra-oauth2--openid-connect-server)\n  - [Ory Oathkeeper: Identity \u0026 Access Proxy](#ory-oathkeeper-identity--access-proxy)\n  - [Ory Keto: Access Control Policies as a Server](#ory-keto-access-control-policies-as-a-server)\n- [Security](#security)\n  - [Disclosing vulnerabilities](#disclosing-vulnerabilities)\n- [Benchmarks](#benchmarks)\n- [Telemetry](#telemetry)\n- [Documentation](#documentation)\n  - [Guide](#guide)\n  - [HTTP API documentation](#http-api-documentation)\n  - [Upgrading and Changelog](#upgrading-and-changelog)\n  - [Command line documentation](#command-line-documentation)\n  - [Develop](#develop)\n    - [Dependencies](#dependencies)\n    - [Formatting Code](#formatting-code)\n    - [Running Tests](#running-tests)\n      - [Short Tests](#short-tests)\n      - [Regular Tests](#regular-tests)\n    - [E2E Tests](#e2e-tests)\n      - [OpenID Connect Conformity Tests](#openid-connect-conformity-tests)\n    - [Build Docker](#build-docker)\n    - [Run the Docker Compose quickstarts](#run-the-docker-compose-quickstarts)\n    - [Add a new migration](#add-a-new-migration)\n- [Libraries and third-party projects](#libraries-and-third-party-projects)\n\n\u003c!-- END doctoc generated TOC please keep comment here to allow auto update --\u003e\n\n## What is Ory Hydra?\n\nOry Hydra is a server implementation of the OAuth 2.0 authorization framework\nand the OpenID Connect Core 1.0. Existing OAuth2 implementations usually ship as\nlibraries or SDKs such as\n[node-oauth2-server](https://github.com/oauthjs/node-oauth2-server) or\n[Ory Fosite](https://github.com/ory/fosite/issues), or as fully featured\nidentity solutions with user management and user interfaces, such as\n[Keycloak](https://www.keycloak.org).\n\nImplementing and using OAuth2 without understanding the whole specification is\nchallenging and prone to errors, even when SDKs are being used. The primary goal\nof Ory Hydra is to make OAuth 2.0 and OpenID Connect 1.0 better accessible.\n\nOry Hydra implements the flows described in OAuth2 and OpenID Connect 1.0\nwithout forcing you to use a \"Hydra User Management\" or some template engine or\na predefined front-end. Instead, it relies on HTTP redirection and cryptographic\nmethods to verify user consent allowing you to use Ory Hydra with any\nauthentication endpoint, be it [Ory Kratos](https://github.com/ory/kratos),\n[authboss](https://github.com/go-authboss/authboss),\n[User Frosting](https://www.userfrosting.com/) or your proprietary Java\nauthentication.\n\n### Who's using it?\n\n\u003c!--BEGIN ADOPTERS--\u003e\n\nThe Ory community stands on the shoulders of individuals, companies, and\nmaintainers. The Ory team thanks everyone involved - from submitting bug reports\nand feature requests, to contributing patches and documentation.

In-depth docs are\navailable as well:\n\n- The documentation is available [here](https://www.ory.sh/docs/hydra).\n- The REST API documentation is available\n  [here](https://www.ory.sh/docs/hydra/sdk/api).\n\n### Installation\n\nHead over to the\n[Ory Developer Documentation](https://www.ory.sh/docs/hydra/install) to learn\nhow to install Ory Hydra on Linux, macOS, Windows, and Docker and how to build\nOry Hydra from source.\n\n## Ecosystem\n\n\u003c!--BEGIN ECOSYSTEM--\u003e\n\nWe build Ory on several guiding principles when it comes to our architecture\ndesign:\n\n- Minimal dependencies\n- Runs everywhere\n- Scales without effort\n- Minimize room for human and network errors\n\nOry's architecture is designed to run best on a Container Orchestration system\nsuch as Kubernetes, CloudFoundry, OpenShift, and similar projects. Binaries are\nsmall (5-15MB) and available for all popular processor types (ARM, AMD64, i386)\nand operating systems (FreeBSD, Linux, macOS, Windows) without system\ndependencies (Java, Node, Ruby, libxml, ...).\n\n### Ory Kratos: Identity and User Infrastructure and Management\n\n[Ory Kratos](https://github.com/ory/kratos) is an API-first Identity and User\nManagement system that is built according to\n[cloud architecture best practices](https://www.ory.sh/docs/next/ecosystem/software-architecture-philosophy).\nIt implements core use cases that almost every software application needs to\ndeal with: Self-service Login and Registration, Multi-Factor Authentication\n(MFA/2FA), Account Recovery and Verification, Profile, and Account Management.\n\n### Ory Hydra: OAuth2 \u0026 OpenID Connect Server\n\n[Ory Hydra](https://github.com/ory/hydra) is an OpenID Certified™ OAuth2 and\nOpenID Connect Provider which easily connects to any existing identity system by\nwriting a tiny \"bridge\" application. It gives absolute control over the user\ninterface and user experience flows.\n\n### Ory Oathkeeper: Identity \u0026 Access Proxy\n\n[Ory Oathkeeper](https://github.com/ory/oathkeeper) is a BeyondCorp/Zero Trust\nIdentity \u0026 Access Proxy (IAP) with configurable authentication, authorization,\nand request mutation rules for your web services: Authenticate JWT, Access\nTokens, API Keys, mTLS; Check if the contained subject is allowed to perform the\nrequest; Encode resulting content into custom headers (`X-User-ID`), JSON Web\nTokens and more!\n\n### Ory Keto: Access Control Policies as a Server\n\n[Ory Keto](https://github.com/ory/keto) is a policy decision point. It uses a\nset of access control policies, similar to AWS IAM Policies, in order to\ndetermine whether a subject (user, application, service, car, ...) is authorized\nto perform a certain action on a resource.\n\n\u003c!--END ECOSYSTEM--\u003e\n\n## Security\n\n_Why should I use Ory Hydra? It's not that hard to implement two OAuth2\nendpoints and there are numerous SDKs out there!_\n\nOAuth2 and OAuth2 related specifications are over 400 written pages.\nImplementing OAuth2 is easy, getting it right is hard. Ory Hydra is trusted by\ncompanies all around the world, has a vibrant community and faces millions of\nrequests in production each day. Of course, we also compiled a security guide\nwith more details on cryptography and security concepts. Read\n[the security guide now](https://www.ory.sh/docs/hydra/security-architecture).\n\n### Disclosing vulnerabilities\n\nIf you think you found a security vulnerability, please refrain from posting it\npublicly on the forums, the chat, or GitHub. You can find all info for\nresponsible disclosure in our\n[security.txt](https://www.ory.sh/.well-known/security.txt).\n\n## Benchmarks\n\nOur continuous integration runs a collection of benchmarks against Ory Hydra.\nYou can find the results [here](https://www.ory.sh/docs/performance/hydra).\n\n## Telemetry\n\nOur services collect summarized, anonymized data that can optionally be turned\noff. Click [here](https://www.ory.sh/docs/ecosystem/sqa) to learn more.\n\n## Documentation\n\n### Guide\n\nThe full Ory Hydra documentation is available\n[here](https://www.ory.sh/docs/hydra).\n\n### HTTP API documentation\n\nThe HTTP API is documented [here](https://www.ory.sh/docs/hydra/sdk/api).\n\n### Upgrading and Changelog\n\nNew releases might introduce breaking changes. To help you identify and\nincorporate those changes, we document these changes in\n[CHANGELOG.md](./CHANGELOG.md).\n\n### Command line documentation\n\nRun `hydra -h` or `hydra help`.\n\n### Develop\n\nWe love all contributions! Please read our\n[contribution guidelines](./CONTRIBUTING.md).\n\n#### Dependencies\n\nYou need Go 1.13+ with `GO111MODULE=on` and (for the test suites):\n\n- Docker and Docker Compose\n- Makefile\n- NodeJS / npm\n\nIt is possible to develop Ory Hydra on Windows, but please be aware that all\nguides assume a Unix shell like bash or zsh.\n\n#### Formatting Code\n\nYou can format all code using `make format`. Our CI checks if your code is\nproperly formatted.\n\n#### Running Tests\n\nThere are three types of tests you can run:\n\n- Short tests (do not require a SQL database like PostgreSQL)\n- Regular tests (do require PostgreSQL, MySQL, CockroachDB)\n- End to end tests (do require databases and will use a test browser)\n\nAll of the above tests can be run using the makefile. See the commands below.\n\n**Makefile commands**\n\n```shell\n# quick tests\nmake quicktest\n\n# regular tests\nmake test\ntest-resetdb\n\n# end-to-end tests\nmake e2e\n```\n\n##### Short Tests\n\nIt is recommended to use the make file to run your tests using `make quicktest`\n, however, you can still use the `go test` command.\n\n**Please note**:\n\nAll tests run against a sqlite in-memory database, thus it is required to use\nthe `-tags sqlite` build tag.\n\nShort tests run fairly quickly. You can either test all of the code at once:\n\n```shell script\ngo test -v -failfast -short -tags sqlite ./...\n```\n\nor test just a specific module:\n\n```shell script\ngo test -v -failfast -short -tags sqlite ./client\n```\n\nor a specific test:\n\n```shell script\ngo test -v -failfast -short -tags sqlite -run ^TestName$ ./...\n```\n\n##### Regular Tests\n\nRegular tests require a database set up. Our test suite is able to work with\ndocker directly (using [ory/dockertest](https://github.com/ory/dockertest)) but\nwe encourage to use the Makefile instead. Using dockertest can bloat the number\nof Docker Images on your system and are quite slow. Instead we recommend doing:\n\n```shell script\nmake test\n```\n\nPlease be aware that `make test` recreates the databases every time you run\n`make test`. This can be annoying if you are trying to fix something very\nspecific and need the database tests all the time. In that case we suggest that\nyou initialize the databases with:\n\n```shell script\nmake test-resetdb\nexport TEST_DATABASE_MYSQL='mysql://root:secret@(127.0.0.1:3444)/mysql?parseTime=true\u0026multiStatements=true'\nexport TEST_DATABASE_POSTGRESQL='postgres://postgres:secret@127.0.0.1:3445/postgres?sslmode=disable'\nexport TEST_DATABASE_COCKROACHDB='cockroach://root@127.0.0.1:3446/defaultdb?sslmode=disable'\n```\n\nThen you can run `go test` as often as you'd like:\n\n```shell script\ngo test -p 1 ./...\n\n# or in a module:\ncd client; go test .\n```\n\n#### E2E Tests\n\nThe E2E tests use [Cypress](https://www.cypress.io) to run full browser tests.\nYou can execute these tests with:\n\n```\nmake e2e\n```\n\nThe runner will not show the Browser window, as it runs in the CI Mode\n(background). That makes debugging these type of tests very difficult, but\nthankfully you can run the e2e test in the browser which helps with debugging!\nJust run:\n\n```shell script\n./test/e2e/circle-ci.bash memory --watch\n\n# Or for the JSON Web Token Access Token strategy:\n# ./test/e2e/circle-ci.bash memory-jwt --watch\n```\n\nor if you would like to test one of the databases:\n\n```shell script\nmake test-resetdb\nexport TEST_DATABASE_MYSQL='mysql://root:secret@(127.0.0.1:3444)/mysql?parseTime=true\u0026multiStatements=true'\nexport TEST_DATABASE_POSTGRESQL='postgres://postgres:secret@127.0.0.1:3445/postgres?sslmode=disable'\nexport TEST_DATABASE_COCKROACHDB='cockroach://root@127.0.0.1:3446/defaultdb?sslmode=disable'\n\n# You can test against each individual database:\n./test/e2e/circle-ci.bash postgres --watch\n./test/e2e/circle-ci.bash memory --watch\n./test/e2e/circle-ci.bash mysql --watch\n# ...\n```\n\nOnce you run the script, a Cypress window will appear. Hit the button \"Run all\nSpecs\"!\n\nThe code for these tests is located in\n[./cypress/integration](./cypress/integration) and\n[./cypress/support](./cypress/support) and\n[./cypress/helpers](./cypress/helpers). The website you're seeing is located in\n[./test/e2e/oauth2-client](./test/e2e/oauth2-client).\n\n##### OpenID Connect Conformity Tests\n\nTo run Ory Hydra against the OpenID Connect conformity suite, run\n\n```shell script\n$ test/conformity/start.sh --build\n```\n\nand then in a separate shell\n\n```shell script\n$ test/conformity/test.sh\n```\n\nRunning these tests will take a significant amount of time which is why they are\nnot part of the CI pipeline.\n\n#### Build Docker\n\nYou can build a development Docker Image using:\n\n```shell script\nmake docker\n```\n\n#### Run the Docker Compose quickstarts\n\nIf you wish to check your code changes against any of the docker-compose\nquickstart files, run:\n\n```shell script\nmake docker\ndocker compose -f quickstart.yml up # ....\n```\n\n#### Add a new migration\n\n1. `mkdir persistence/sql/src/YYYYMMDD000001_migration_name/`\n2. Put the migration files into this directory, following the standard naming\n   conventions. If you wish to execute different parts of a migration in\n   separate transactions, add split marks (lines with the text `--split`) where\n   desired. Why this might be necessary is explained in\n   https://github.com/gobuffalo/fizz/issues/104.\n3. Run `make persistence/sql/migrations/\u003cmigration_id\u003e` to generate migration\n   fragments.\n4. If an update causes the migration to have fewer fragments than the number\n   already generated, run\n   `make persistence/sql/migrations/\u003cmigration_id\u003e-clean`. This is equivalent to\n   a `rm` command with the right parameters, but comes with better tab\n   completion.\n5. Before committing generated migration fragments, run the above clean command\n   and generate a fresh copy of migration fragments to make sure the `sql/src`\n   and `sql/migrations` directories are consistent.\n\n## Libraries and third-party projects\n\nOfficial:\n\n- [User Login \u0026 Consent Example](https://github.com/ory/hydra-login-consent-node)\n\nCommunity:\n\n- Visit\n  [this document for an overview of community projects and articles](https://www.ory.sh/docs/ecosystem/community)\n\nDeveloper Blog:\n\n- Visit the [Ory Blog](https://www.ory.sh/blog/) for guides, tutorials and\n  articles around Ory Hydra and the Ory ecosystem.\n","funding_links":["https://patreon.com/_ory","https://opencollective.com/ory"],"categories":["API Security","Go","Install from Source","Server Implementation","Auth","server","Authentication","后端开发框架及项目","Backend frameworks \u0026 libraries","HarmonyOS","OpenID Providers (OP)","Recently Updated","Openai","docker","`Authentication Development`","Implementations(Examples/Demos)","Ecosystem","OAuth2 \u0026 OpenID"],"sub_categories":["Desktop","Network Tools","Verifiable Credentials","\u003ca name=\"authN-golang\"\u003e\u003c/a\u003eGolang","管理面板","Windows Manager","[Jul 26, 2025](/content/2025/07/26/README.md)","Invalidating JWT","Other tools"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fory%2Fhydra","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fory%2Fhydra","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fory%2Fhydra/lists"}
