I made Chaos Proxy, a tool to inject chaos into API requests for testing and development.

You can simulate latency, random failures, dropped connections, and rate limits using a simple YAML config or code. Great for testing how your app handles slow, flaky, or failing APIs.

Simulate network issues and error responses Test client retry and resilience logic Easy config, extensible, and open source.
