Open Policy Agent

Open Policy Agent (OPA) is an open-source project that provides a flexible and powerful policy engine for cloud-native environments. OPA enables users to define and enforce policies across their infrastructure, applications, and services through a declarative language called Rego. OPA integrates seamlessly with popular tools and frameworks like Kubernetes, Istio, and Envoy, making it easy to implement fine-grained access control, security, and compliance policies.

Open Policy Agent publishes 8 APIs on the APIs.io network, including Compile API, Config API, Data API, and 5 more. Tagged areas include Policies and Standards.

The Open Policy Agent catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

Open Policy Agent’s developer surface includes documentation, getting-started guide, authentication, engineering blog, changelog, Stack Overflow tag, and 16 more developer resources.
