Chaos Engineering Tools

A curated 2026 directory of 21 leading chaos engineering tools spanning Kubernetes fault injection, container chaos, network resilience testing, and cloud instance termination.

• Chaos Monkey (Netflix)

  Responsible for randomly terminating instances in production to ensure that engineers implement their services to be resilient to instance failures.

• Chaosblade

  An easy to use and powerful chaos engineering experiment toolkit, open sourced by Alibaba.

• Chaos Mesh

  A powerful chaos engineering platform for Kubernetes, and a CNCF incubating project.

• Litmus

  A CNCF-hosted, open-source chaos engineering platform that provides tools to orchestrate chaos on Kubernetes to help SREs find weaknesses in their deployments.

• Chaos Toolkit

  Aims to be the simplest and easiest way to explore building your own chaos engineering experiments as code.

• PowerfulSeal

  Injects failure into your Kubernetes clusters, so that you can detect problems as early as possible. Supports writing scenarios describing complete chaos experiments.

• Toxiproxy

  A TCP proxy to simulate network and system conditions, built for testing, CI, and development environments with deterministic tampering of connections.

• Kube DOOM

  Kill pods inside your Kubernetes cluster by shooting them in Doom.

• Muxy

  Proxy for simulating real-world distributed system failures to improve resilience in your applications.

• Gremlin

  Enterprise reliability management platform combining chaos engineering and fault injection to find and fix reliability risks before they cause outages.

• Vegeta

  A versatile HTTP load testing tool built out of a need to drill HTTP services with a constant request rate.

• Pystol

  The fault injection platform, created to demonstrate the correlation between fault injection actions and changes in Kubernetes cluster behavior.

• Pumba

  Chaos testing, network emulation, and stress testing tool for Docker, containerd, and Podman containers.

• steadybit

  Enterprise reliability testing platform that helps identify the weak spots that matter with no-code chaos experiments.

• Mangle (VMware)

  Enables you to run chaos engineering experiments seamlessly against applications and infrastructure components to assess resiliency and fault tolerance.

• Verica

  Uses continuous verification and chaos engineering to make systems more secure and less vulnerable to costly incidents.

• DRAX

  The DC/OS Resilience Automated Xenodiagnosis tool. Helps test DC/OS deployments with a Chaos Monkey-inspired, proactive and invasive testing approach.

• Chaos Lambda

  Increases the rate at which service failures occur, since AWS EC2 instances are volatile and bound to fail, helping teams build services that handle them gracefully.

• Chaos Monkey for Spring Boot

  Brings Chaos Monkey-style attacks to Spring Boot applications, hooking in via a dedicated profile to test fallback and resilience behavior.

• WireMock

  Open source tool for building mock APIs, including fault simulation to test an application's resilience to network faults and delays.

• WireMock Cloud (formerly MockLab)

  AI-native API simulation platform for rapid, parallel development
