Langfuse Rate Limits

Langfuse cloud throttling is primarily quota-based on monthly units (traces, observations, scores). Enterprise accounts can negotiate custom rate limits. Self-hosted installations are limited only by the operator's own infrastructure.

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

It captures 4 rate-limit definitions, measuring unit, varies, and none.

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 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include AI, LLM, Observability, Open Source, and Evaluations.

Policies

Backoff Strategy
Honor 429 responses with exponential backoff and jitter; SDKs handle retry automatically.
Trace Batching
SDKs batch trace ingestion calls before flushing, reducing per-request overhead.
OpenTelemetry Path
Use the OTel ingestion endpoint where possible; it is the recommended, higher-throughput path.
