Semaphore Rate Limits

Semaphore enforces platform-level concurrency and queue limits on pipeline execution and job scheduling. The REST API uses token-based authentication and HTTPS for all requests. Specific HTTP rate limiting thresholds for the API are not publicly documented; pipeline queue limits and concurrent job caps are the primary operational constraints.

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

It captures 6 rate-limit definitions.

Tagged areas include CI/CD, Continuous Integration, Continuous Delivery, Pipelines, and Workflows.
