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

Typed, resilient HTTP clients for Python, sync and async

warpweft

A declarative framework for resilient, observable service components.

grelmicro-core

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

baldur-framework

Self-healing reliability layer for Python — circuit breaker, retry, and fallback behind a single decorator. Framework-agnostic core with Django, FastAPI, Flask, and Celery adapters.

interlock-cb

Circuit breaker for Python: sync + async in one class, sliding-window rate, slow-call detection, Polly-style resilience pipeline, type-safe API

grelmicro

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

avo

Observable AI agent runtime uniting Claude, ChatGPT, and Gemini subscriptions with multi-tier failover down to local Ollama. Replayable SQLite ledger.

fmdtools

System Resilience Modelling, Simulation, and Assessment in Python

redress

Policy-driven failure handling for Python services.

clientwright

HTTP client platform: one resilience and observability core with adapters for httpx, aiohttp, requests, urllib3 and friends

mnfst

Manifest SDK for Python. See every API call your app makes, heal the ones that fail, and know what will break next.

esapay

Autonomous Multi-Gateway Payment Resilience & Self-Healing Financial Infrastructure for Sovereign Indian Rails

backon

Function decoration for backoff and retry — modern, fast, and zero dependencies

shadowbox

Model the system. Experiment safely. Deterministic what-if simulation for backend architectures — CLI, API and dashboards. Python + TypeScript, local-first, no paid services.

llmock

Local mock server for testing LLM retries, fallbacks, and provider failure handling without spending tokens.

nrel-erad

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

asyncbreaker

Asyncio-first Circuit Breaker for Python: fail-fast calls, HALF_OPEN trials, and Redis-backed shared state.

rotapool

Generic async resource pool with rotation, cooldown, and retry

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.

quarantine-py

When one bad item crashes your loop of 10,000 - don't crash. Set it aside, keep going, fix it later.

aws-chaos-engineering-framework

Break AWS safely before reality does: enterprise-grade FIS orchestration, GovCloud guardrails, rollback, and audit-ready evidence in one Python file.

relinker

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

pico-resilience

Resilience AOP for the Pico ecosystem: @retryable, @circuit_breaker and @timeout over pico-ioc method interception. Zero-config via pico-boot.
