Why we included this project

OPA is a policy engine you run as a standalone decision service: write rules in Rego once, and the same policies govern Kubernetes admission, API requests, and microservice calls, so each application doesn't have to embed its own authorization logic. Policies are data and code, so you can version and test them like any other artifact and audit them when needed. In AI deployments OPA often sits in front of LLM API calls to apply guardrails, keeping policy decisions explicit and reviewable rather than scattered through app code. Teams juggling consistent compliance rules across many services will find it a practical building block.
