Open Policy Agent Rate Limits

Open Policy Agent has no centrally enforced rate limits because the engine is operated by the consumer. Throughput depends on the deployment topology (sidecar, daemonset, library) and underlying hardware. Operators commonly front OPA with their own gateway and apply throttling there.

Open Policy Agent Rate Limits is the machine-readable rate-limit profile for Open Policy Agent on the APIs.io network, in the API Commons Rate Limits shape.

It captures 1 rate-limit definition, measuring varies.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Policies, Standards, Rate Limiting, and Open Source.

Limits

Self-hosted throughput deployment
varies
see operator deployment sizing
OPA throughput is bounded by host CPU and policy complexity; benchmark for your workload.

Policies

Operator-controlled
Because OPA is self-hosted, all rate limiting is the operator's responsibility — typically enforced by an upstream API gateway, service mesh, or ingress controller.
Decision caching
Use bundle service polling and decision caching to reduce evaluation pressure under high query rates.
