BreakerMachines is a production-ready circuit breaker implementation for Ruby that prevents cascade failures in distributed systems. Built on the battle-tested state_machines gem, it provides a clean DSL, thread-safe operations, multiple storage backends, and comprehensive introspection tools. Unlike other solutions, BreakerMachines prioritizes safety by avoiding dangerous forceful timeouts while supporting fallback chains, jitter, and event callbacks.

ThrottleMachines provides ultra-thin, elegant rate limiting with temporal precision for distributed systems.
