The rules are clear. The system enforces them in real time. No hidden code, no special cases, no manual overrides. Lean Open Policy Agent (OPA) is what makes this possible without slowing the machine down.
Lean OPA strips policy enforcement to its essentials—fast decisions, minimal footprint, straightforward deployment. It executes the Rego language without the bulky runtime, giving you the same powerful, declarative control but tuned for speed. This matters when your service calls hit hundreds or thousands per second and policy checks have to keep pace.
Instead of loading huge bundles or container-heavy builds, Lean OPA can embed directly into your application or run as a light sidecar. Policies stay standard—written in Rego—so you gain all the benefits of Open Policy Agent without sacrificing performance. Audit, compliance, access control, and feature gating become consistent across your stack.
Lean OPA integrates seamlessly with CI/CD pipelines. Policies are versioned, tested, and shipped just like code. You can hot-reload policy files, or bake them into an immutable build. The reduced memory usage and shorter startup times make it well-suited for short-lived processes, serverless workloads, or high-scale microservices.
