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.
