## What is Ory Keto?

Ory Keto is an open source implementation of "Zanzibar: Google's Consistent,
Global Authorization System". It follows
[cloud architecture best practices](https://www.ory.com/docs/ecosystem/software-architecture-philosophy)
and focuses on:

- Scalable permission checks based on the Zanzibar model
- The Ory Permission Language for defining access control policies
- Relationship-based access control (ReBAC)
- Low latency permission checks (sub-10ms)
- Horizontal scaling to billions of relationships
- Consistency and high availability

We recommend starting with the
[Ory Keto introduction docs](https://www.ory.com/docs/keto) to learn more about
its architecture, feature set, and how it compares to other systems.

### Why Ory Keto

Ory Keto is designed to:

- Implement Google's Zanzibar authorization model at scale
- Provide low-latency permission checks for billions of relationships
- Support the Ory Permission Language for flexible access control
- Work with any identity provider through integration points
- Scale horizontally without effort
- Fit into modern cloud native environments such as Kubernetes and managed
  platforms

## Deployment options

You can run Ory Keto 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 Keto on the Ory Network

The [Ory Network](https://www.ory.com/cloud) is the fastest way to use Ory
services in production. **Ory Permissions** is powered by the open source Ory
Keto server and is API compatible.

The Ory Network provides:

- Low latency permission checks based on Google's Zanzibar model with built-in
  support for the Ory Permission Language
- 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
- OAuth2 and OpenID Connect for single sign on, API access, and machine to
  machine authorization
- 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](https://www.ory.com/pricing)

Sign up for a
[free developer account](https://console.ory.sh/registration?utm_source=github&utm_medium=banner&utm_campaign=keto-readme)
to get started.

### Self-host Ory Keto

You can run Ory Keto yourself for full control over infrastructure, deployment,
and customization.

The [install guide](https://www.ory.com/docs/keto/install) explains how to:

- Install Keto on Linux, macOS, Windows, and Docker
- Configure databases such as PostgreSQL, MySQL, and CockroachDB
- Deploy to Kubernetes and other orchestration systems
- Build Keto 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 Keto as part of a business-critical system, you should use a
commercial agreement to reduce operational and security risk. The **Ory
Enterprise License (OEL)** layers on top of self-hosted Keto 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](https://www.ory.com/ory-enterprise-license) and access
to the Ory Enterprise Docker registry. To learn more,
[contact the Ory team](https://www.ory.com/contact/).

## Quickstart

Install the [Ory CLI](https://www.ory.com/docs/guides/cli/installation) and
create a new project to try Ory Permissions.

```bash
# 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
```

Create a namespace with the Ory Permission Language:

```bash
# Write a simple configuration with one namespace
echo "class Document implements Namespace {}" > config.ts

# Apply that configuration
ory patch opl -f file://./config.ts

# Create a relationship that grants tom access to a document
echo "Document:secret#read@tom" \
  | ory parse relation-tuples --format=json - \
  | ory create relation-tuples -

# List all relationships
ory list relation-tuples

# Check if tom can read the document
ory check permission Document:secret read tom
```

## Ecosystem

<!--BEGIN 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](https://github.com/ory/kratos) is an API-first Identity and User
Management system that is built according to
[cloud architecture best practices](https://www.ory.com/docs/next/ecosystem/software-architecture-philosophy).
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](https://github.com/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](https://github.com/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](https://github.com/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.

<!--END ECOSYSTEM-->

## Documentation

The full Ory Keto documentation is available at
[www.ory.com/docs/keto](https://www.ory.com/docs/keto), including:

- [Installation guides](https://www.ory.com/docs/keto/install)
- [Configuration reference](https://www.ory.com/docs/keto/reference/configuration)
- [HTTP API documentation](https://www.ory.com/docs/keto/sdk/api)
- [Ory Permission Language guide](https://www.ory.com/docs/keto/modeling/create-permission-model)
