Open Policy Agent
An open-source, general-purpose policy engine for unified, context-aware policy enforcement across the stack.
What is Open Policy Agent?
Open Policy Agent (OPA) is an open-source policy engine that enables unified, context-aware policy enforcement across cloud-native and traditional infrastructure. It solves the problem of fragmented, hardcoded policy logic by providing a declarative language (Rego) to define rules that answer questions about authorization, compliance, and resource management. OPA decouples policy decisions from application code, allowing policies to be managed and updated independently.
Platform engineers, DevOps teams, and security architects building or managing cloud-native infrastructure, Kubernetes clusters, microservices, and multi-cloud environments who need consistent policy enforcement.
Developers choose OPA because it provides a single, unified policy engine that works across the entire stack, eliminating the need for disparate, hardcoded policy logic. Its declarative Rego language is purpose-built for policy, and its CNCF graduation ensures enterprise-grade stability and community support.
