⚡OPAL⚡Open Policy Administration LayerWhat is OPAL?OPAL is an administration layer for Policy Engines such asOpen Policy Agent (OPA), andAWS' Cedar Agentdetecting changes to both policy and policy data in realtime and pushing live updates to your agents. OPAL brings open-policy up to the speed needed by live applications.As your application state changes (whether it's via your APIs, DBs, git, S3 or 3rd-party SaaS services), OPAL will make sure your services are always in sync with the authorization data and policy they need (and only those they need).Check out our main site atOPAL.ac,this videobriefly explaining OPAL and how it works with OPA, and a deeper dive into it atthis OWASP DevSlop talk.Why use OPAL?OPAL is the easiest way to keep your solution's authorization layer up-to-date in realtime. It aggregates policy and data from across the field and integrates them seamlessly into the authorization layer, and is microservices and cloud-native.OPA + OPAL == 💜While 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.
This is especially true in applications, where each user interaction or API call may affect access-control decisions.
OPAL runs in the background, supercharging policy-agents, keeping them in sync with events in realtime.AWS Cedar + OPAL == 💪Cedar 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?

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 source) to load it in to its managed OPA instance.📖   For further reading check out ourBlog.CommunityCome talk to us about OPAL, or authorization in general - we would love to hear from you ❤️You can raise questions and ask for features to be added to the road-map in ourGithub discussions, report issues inGithub issues, follow us on Twitter to get the latest OPAL updates, and join our Slack community to chat about authorization, open-source, realtime communication, tech, or anything else!If you are using our project, please consider giving us a ⭐️Contributing to OPALPull requests are welcome!
