Traefik Rate Limits

Traefik Proxy is self-hosted software, so request throttling is configured by the operator (via the RateLimit / InFlightReq HTTP middlewares and the InFlightConn TCP middleware) rather than imposed by Traefik Labs as a vendor. Traefik Hub adds the APIPlan CRD, which carries documented rate and quota fields (limit, period, bucket) that operators apply per managed subscription. The Hub control plane's own API-management quotas are not published on the public site and are part of each customer's commercial agreement.

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

It captures 5 rate-limit definitions, measuring requests, in-flight requests, in-flight TCP connections, and varies.

The profile also includes 5 backoff/retry policies defined.

Tagged areas include API Gateway, API Management, Kubernetes, and Rate Limiting.

in-flight TCP connections
defined by the operator via the InFlightConn TCP middleware (amount field)

Policies

HTTP RateLimit Middleware
Configurable per router or service. Fields - average (req/period), burst (token-bucket capacity), period (e.g. 1s, 1m), and optional sourceCriterion to scope the limit to a header, IP, or ipStrategy. Returns HTTP 429 when exceeded.
HTTP InFlightReq Middleware
Caps concurrent in-flight HTTP requests per source criterion. Returns HTTP 429 when the configured `amount` is reached.
TCP InFlightConn Middleware
Caps concurrent TCP connections per remote IP. Refuses connections once the configured `amount` is reached.
Hub APIPlan
Kubernetes CRD attached to managed subscriptions. Carries a rateLimit block (limit, period, bucket) and a quota block (limit, period, bucket). Bucket controls scoping - per subscription, per application, or per application-API pair. Exceeding either yields HTTP 429.
Contact Sales for Hub Quotas
Provider-side quotas on the Hub control plane are not published; the commercial contract sets the operational limits.
