| description.long | An open-source framework that lets developers declare and execute chaos engineering experiments using code files, enabling discovery of system weaknesses through intentional disruption and integration with CI/CD pipelines. | A Go-based TCP proxy tool designed for testing and CI environments that injects controlled network failures, latency, and corruption to verify applications handle degraded connectivity gracefully. Enables developers to simulate chaos deterministically or with randomization during testing. |
