A fast, asynchronous, rack-compatible web server.

Execution rate limiting for Async

A production-grade lightweight background job scheduler built on the Fiber::Scheduler interface itself, not on any one implementation: it runs under Async/Falcon, Itsi, or anything else that installs a scheduler. Single event loop with min-heap timer, skip-overlapping execution, jitter, monotonic clock intervals, semaphore concurrency control, and deterministic worker sharding.

A supervisor for managing multiple container processes.

Advanced concurrency control and resource limiting for Falcon web server.
