KrakenD · Rate Limits

Krakend Rate Limits

KrakenD is self-hosted software, not a hosted API service, so it does not impose vendor-side rate limits on its customers. Operators configure their own rate limiting using the built-in `qos/ratelimit/router` (per-endpoint) and `qos/ratelimit/proxy` (per-backend) middleware, plus the Enterprise `security/policies` layer for advanced quotas. License usage is unconstrained — Enterprise pricing explicitly is not linked to API count or throughput.

Krakend Rate Limits is the machine-readable rate-limit profile for KrakenD on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests_per_second.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include Rate Limiting, API Gateway, and API Aggregation.

Policies

Operator-defined throttling
Rate limiting in KrakenD is configured by the operator in krakend.json; it is not enforced by the vendor.
Token-bucket
Built-in rate limiters use a token-bucket algorithm with `max_rate` (steady) and `capacity` (burst).
Standard headers
When throttled, KrakenD returns 429 and may emit X-RateLimit-Limit / X-RateLimit-Remaining / X-RateLimit-Reset depending on plugin configuration.
Stateless scaling
KrakenD is stateless; rate-limit state is per-instance unless backed by a shared store. Horizontal scaling effectively multiplies the configured rate per instance.
