A production-grade lightweight scheduler built on top of Async. Single event loop with min-heap timer, skip-overlapping execution, jitter, monotonic clock intervals, semaphore concurrency control, and deterministic worker sharding. Designed for Falcon but works with any Async-based application.

A high-performance NATS client built on the async framework, providing fiber-based concurrency for better resource efficiency. Built on top of nats-pure with full API compatibility. WARNING: This project was developed entirely by the Windsurf AI code agent and should be considered experimental.

Angstrom is an Mongrel2 fronted, actor-based web development framework similar in style to sinatra. With natively-threaded interpreters (Rubinius2), Angstrom provides true concurrency and high stability, by design.

Concurrency based polling.

Allows you to protect the execution of a block against concurrency.

Omnibus concurrency library for Ruby

HttpLoader is a powerful, high-concurrency performance and load testing console tool. Built on asynchronous Ruby, it evaluates server limits by opening massive numbers of persistent connections and holding them open. It utilizes event-driven I/O with optional periodic ping requests to keep connec...

A collection of utility helpers for Ruby including graphing, configuration management, concurrency, system operations, multimedia handling, and more.

Third approach to EventMachine lightweight concurrency. Runs declared methods and blocks in sequence, each in one tick. So allows calls chaining with keeping the EventMachine multiplexing facility on.

A wrapper that allows method calls to multiple objects with various concurrency models

Prevent multiple sidekiq jobs with the same arguments from running at the same time.

Locker is a locking mechanism for limiting the concurrency of ruby code using the database. It presently only works with PostgreSQL.
