Toxiproxy vs ChaosBlade: open-source chaos and resilience tools compared

Metrics as of , from the GitHub or GitLab API of each repository. Refreshed monthly.

Summary

Toxiproxy: TCP proxy with an HTTP API for simulating latency, outages and other network faults in tests and CI.

ChaosBlade: Chaos engineering toolkit from Alibaba for injecting faults into hosts, containers, Kubernetes, Java and C++ applications.

Both are listed under Chaos and resilience. The table gives repository metrics from the GitHub API with their fetch date, then the documented facts used for every comparison in this category, each linked to the README or docs page it comes from. A cell reads "not documented" when the fact was not found in the project's documentation (1 of 10 fact cells here); that does not mean the feature is absent.

When each fits

Written from each project's documented scope, not from preference. Neither tool is ranked.

Toxiproxy

Fits projects that simulate network conditions in tests; its README describes a TCP proxy whose connections are manipulated over HTTP. source: README

ChaosBlade

Fits projects that inject faults into hosts, containers, Kubernetes and Java or C++ applications; its README describes CLI and HTTP invocation methods. source: README
