It aggregates policy and data from across the field and integrates them seamlessly into the authorization layer, and is microservices and cloud-native.\n\nHere are some of the main use cases for using OPAL:\n* **End-to-End [Fine-Grained Authorization](https:\u002F\u002Fwww.permit.io\u002Fblog\u002Fwhat-is-fine-grained-authorization-fga) service** that can be used with any policy language or data store\n* [Google-Zanzibar](https:\u002F\u002Fwww.permit.io\u002Fblog\u002Fwhat-is-google-zanzibar) support for Policy as Code engines such as OPA and AWS Cedar\n* Streamline permissions in microservice architectures using [centralized policy configuration with decentralized data](https:\u002F\u002Fwww.permit.io\u002Fblog\u002Fbest-practices-for-implementing-hybrid-cloud-security) sources and policy engines\n* Manage and automate the deployment of multiple Open Policy Agent engines in a Cloud-Native environment\n\n\u003Cimg src=\"https:\u002F\u002Fgithub.com\u002Fpermitio\u002Fopal\u002Fassets\u002F4082578\u002F99d3dd95-a7ff-45c2-805e-3d533f8b1e8c\" alt=\"simplified\" border=\"0\">\n\nOPAL  uses a client-server stateless architecture. OPAL-Servers publish policy and data updates over a lightweight (websocket) PubSub Channel, which OPAL-clients subscribe to via topics. Upon updates, each client fetches data directly (from the source) to load it into its managed Policy Engine instance.\n\n\n### OPA + OPAL == 💜\n\nWhile OPA (Open Policy Agent) decouples policy from code in a highly-performant and elegant way, the challenge of keeping policy agents up-to-date remains.\nThis is especially true in applications, where each user interaction or API call may affect access-control decisions.\nOPAL runs in the background, supercharging policy agents and keeping them in sync with events in real time.\n\n### AWS Cedar + OPAL == 💪\n\nCedar is a very powerful policy language, which powers AWS' AVP (Amazon Verified Permissions) - but what if you want to enjoy the power of Cedar on another cloud, locally, or on premise?\nThis is where [Cedar-Agent](https:\u002F\u002Fgithub.com\u002Fpermitio\u002Fcedar-agent) and OPAL come in.\n\nThis [video](https:\u002F\u002Fyoutu.be\u002FtG8jrdcc7Zo) briefly explains OPAL and how it works with OPA, and a deeper dive into it at [this OWASP DevSlop talk](https:\u002F\u002Fwww.youtube.com\u002Fwatch?v=1_Iz0tRQCH4).\n\n## Who's Using OPAL?\nOPAL is being used as the core engine of Permit.io Authorization Service and serves in production:\n* \\> 10,000 policy engines deployment\n* \\> 100,000 policy changes and data synchronizations every day\n* \\> 10,000,000 authorization checks every day\n\nBesides Permit, OPAL is being used in Production in **Tesla**, **Walmart**, **The NBA**, **Intel**, **Cisco**, **Live-Oak Bank**, and thousands of other development teams and companies of all sizes.\n\n## Documentation\n\n- 📃   [Full documentation is available here](https:\u002F\u002Fdocs.opal.ac)\n- 💡   [Intro to OPAL](https:\u002F\u002Fdocs.opal.ac\u002Fgetting-started\u002Fintro)\n- 🚀   Getting Started:\n\n  OPAL is available both as **python packages** with a built-in CLI as well as pre-built **docker images** ready-to-go.\n\n  - [Play with a live playground environment in docker-compose](https:\u002F\u002Fdocs.opal.ac\u002Fgetting-started\u002Fquickstart\u002Fopal-playground\u002Foverview)\n  \u003C!-- - this tutorial is great for learning about OPAL core features and see what OPAL can do for you. -->\n  - [Try the getting started guide for containers](https:\u002F\u002Fdocs.opal.ac\u002Fgetting-started\u002Frunning-opal\u002Foverview)\n  \u003C!-- - this tutorial will show you how to configure OPAL to your specific needs and run the official docker containers locally or in production. -->\n\n  - [Check out the Helm Chart for Kubernetes](https:\u002F\u002Fgithub.com\u002Fpermitio\u002Fopal-helm-chart)\n\n- A video demo of OPAL is available [here](https:\u002F\u002Fwww.youtube.com\u002Fwatch?v=IkR6EGY3QfM)\n\n- You can also check out this webinar and Q&A about OPAL [on our YouTube channel](https:\u002F\u002Fwww.youtube.com\u002Fwatch?v=A5adHlkmdC0&t=1s)\n  \u003Cbr>\n\n- 💪   TL;DR - This one command will download and run a working configuration of OPAL server and OPAL client on your machine:\n\n```\ncurl -L https:\u002F\u002Fraw.githubusercontent.com\u002Fpermitio\u002Fopal\u002Fmaster\u002Fdocker\u002Fdocker-compose-example.yml \\\n> docker-compose.yml && docker compose up\n```\n\n\u003Cp>\n  \u003Ca href=\"https:\u002F\u002Fasciinema.org\u002Fa\u002F409288\" target=\"_blank\">\n    \u003Cimg src=\"https:\u002F\u002Fasciinema.org\u002Fa\u002F409288.svg\" \u002F>\n  \u003C\u002Fa>\n\u003C\u002Fp>\n\n- 🧠   \"How-To\"s\n\n  - [How to get started with OPAL (Packages and CLI)](https:\u002F\u002Fdocs.opal.ac\u002Fgetting-started\u002Frunning-opal\u002Fas-python-package\u002Foverview)\n\n  - [How to get started with OPAL (Container Images)](https:\u002F\u002Fdocs.opal.ac\u002Fgetting-started\u002Frunning-opal\u002Foverview)\n\n  - [How to trigger Data Updates via OPAL](https:\u002F\u002Fdocs.opal.ac\u002Ftutorials\u002Ftrigger_data_updates)\n\n  - [How to extend OPAL to fetch data from your sources with FetchProviders](https:\u002F\u002Fdocs.opal.ac\u002Ftutorials\u002Fwrite_your_own_fetch_provider)\n\n  - [How to configure OPAL (basic concepts)](https:\u002F\u002Fdocs.opal.ac\u002Ftutorials\u002Fconfigure_opal)\n\n  - [How to Use OPAL with Cedar in a Multi-Language Project](https:\u002F\u002Fwww.permit.io\u002Fblog\u002Fscaling-authorization-with-cedar-and-opal)\n\n- 🎨   [Key concepts and design](https:\u002F\u002Fdocs.opal.ac\u002Foverview\u002Fdesign)\n- 🏗️   [Architecture](https:\u002F\u002Fdocs.opal.ac\u002Foverview\u002Farchitecture)\n\u003Cbr>\n\n📖 For further reading, check out our [Blog](https:\u002F\u002Fio.permit.io\u002Fopal-readme-blog)\n\n## Community\n\n We would love to chat with you about OPAL.
