| description.long | A chaos engineering platform that intentionally injects failures into systems to identify vulnerabilities before they impact users. Provides forward-looking reliability scores and tools to help teams prove their systems can withstand real-world failure scenarios. | 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. |
