Resilience Python Packages

pyresilience

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

httpware

Python HTTP client framework with sync & async clients and built-in resilience

coalestra

Dependency-free async Python library for building consistent, traceable snapshots from multiple read-only sources with caching, batching, single-flight deduplication, retries, circuit breakers, and sync support.

grelmicro

Grelmicro is a lightweight framework/toolkit which is ideal for building async microservices in Python.

relinker

Production-ready Python retry library with sync and async support, exponential backoff, jitter, retry budgets, HTTP helpers, observability, diagnostics, and zero runtime dependencies.

pytryagain

A lightweight, zero-dependency retry decorator for sync and async Python functions.

redress

Policy-driven failure handling for Python services.

bulklink

Typed, zero-dependency bulkhead and bounded-concurrency library for Python asyncio, with FIFO queues, deadlines, metrics, and weighted capacity.

cadence-orchestration

A declarative Python framework for orchestrating service logic with rhythm and precision

fmdtools

System Resilience Modelling, Simulation, and Assessment in Python

fluxgate

Composable Python circuit breaker library — sliding-window failure rate, latency, and consecutive-failure rules.

rotapool

Generic async resource pool with rotation, cooldown, and retry

nrel-erad

Graph based python library for computing resilience metrics for power distribution systems.

interlock-cb

A modern circuit breaker for Python: sync + async, sliding-window rate, slow-call detection, type-safe API.

aioresilience

Async resilience patterns for Python - Circuit breakers, rate limiting, and more

dagpipe-core

Zero-cost, crash-proof LLM pipeline orchestrator. Features disk-based checkpointing, free-tier routing, and structured output. (LangGraph / CrewAI alternative)

faultray

Zero-risk infrastructure chaos simulation — 5 engines, 2000+ scenarios, 3-Layer availability proof. No production fault injection.

ndn-hydra

ndn-hydra: An NDN distributed repository with resiliency coded in python.

apifailover

Domain-neutral multi-API failover engine: try providers in order, fall back per-call or per-item, with provenance tagging and a circuit breaker. Zero dependencies.

resiliens

A Python package for resilient programming.

llmock

Zero-cost local mock server for LLM API resilience testing

toolops

ToolOps is a framework-agnostic middleware SDK that treats every tool call as a first-class operation. By wrapping your tools in a single decorator, you instantly upgrade them with industrial-grade caching, resilience, and observability.

solana-rpc-resilient

Production-grade async Solana RPC client with rate limiting, circuit breaking, provider rotation, and 429 retry.

resilient-http

Resilience layer for Python HTTP clients (smart retries, jitter backoff, circuit breaker)
