opa

OPA is an open source general-purpose policy engine designed for cloud-native environments.

Open Policy Agent (OPA) is a general-purpose policy engine with uses ranging from authorization and admission control to data filtering. OPA provides greater flexibility and expressiveness than hard-coded service logic or ad-hoc domain-specific languages. And it comes with powerful tooling to help you get started.

Here are just a few examples of what you can do with OPA:

• Kubernetes Admission Control
• HTTP API Authorization
• Remote Access
• Data Filtering with Partial Evaluation
