Litmus helps SREs and developers practice chaos engineering in a Cloud-native way. Chaos experiments are published at the ChaosHub (https://hub.litmuschaos.io). Community notes is at https://hackmd.io/a4Zu_sH4TZGeih-xCimi3Q

Chaos Monkey for Spring Boot

Simmy is a chaos-engineering and fault-injection tool, integrating with the Polly resilience project for .NET

YChaos - The Resilience Framework by Yahoo!

A Chaos Engineering swiss army knife

The open source toolbox for resilient operations

Chaotic Testing Harness

Official Docker image for Muxy

A microservice based application to demonstrate how chaos engineering works with Simmy using chaos policies in a distributed system.

An asyncio tcp proxy for network resilience testing

A shared library to help test your code with failure-injection

A small script for running programs with (minimal) network sandboxing

Application based on Chaos Monkey and Chaos Lemur for OpenStack

Chaos Engineering, Reliability and Resilience testing reimagined

April is a resiliency tool that proposes to improve confidence in the microservice architecture

Resilience Testing for Kubernetes Cluster

Chaos engineering and API fuzzing middleware for Express.js and Next.js. Intentionally inject latency, errors, and data corruption to test frontend resilience. Zero runtime dependencies.

Undergraduate Thesis: A Spring Boot benchmark analyzing the Circuit Breaker (Resilience4j) pattern using k6 fault injection.

Chaos engineering & recovery testing with FastAPI, PostgreSQL, Docker, and Locust

AI-driven chaos engineering for microservice ensembles. LangGraph agents automatically plan, execute, and analyze fault-injection experiments via toxiproxy sidecars — locally with Docker Compose or at scale as a Kubernetes Operator.
