Circuit Breaker Python Packages

aiobreaker

Python implementation of the Circuit Breaker pattern.

pyresilience

Unified resilience patterns for Python — retry, circuit breaker, timeout, fallback, bulkhead, rate limiter, and cache in one decorator. Python's Resilience4j.

cachekit

Backend-agnostic caching for Python — intent-based decorators with circuit breaker, distributed locking, Prometheus metrics, and optional zero-knowledge AES-256-GCM encryption, on a Rust-powered core. Zero-config L1 in-memory; scales to Redis, Memcached, File, or CacheKit Cloud.
