Qstash Rate Limits

Rate limits for the QStash API. Operational message publishing APIs have no requests-per-second limit. Management and listing endpoints enforce burst rate limits with a 1-second window. Daily message quotas are enforced per plan. Flow-control features allow users to define their own per-key rate limits and parallelism caps for message delivery.

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

It captures 10 rate-limit definitions.

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.

Tagged areas include Message Queue, Task Scheduling, Serverless, HTTP Messaging, and Background Jobs.

Flow Control - User-Defined Rate Limit per-flow-control-key
Multiple messages sharing the same FlowControl key contribute to the same rate count. This is a user-configured limit, not an Upstash-enforced infrastructure cap.
Flow Control - User-Defined Parallelism per-flow-control-key
Parallelism limits are user-defined and not tied to plan tier. They allow workload shaping without infrastructure-level restrictions.
