What each one is

The product in its own terms, so the numbers below have context.

AWS Fault Injection Service

Leader

A managed service that helps engineering teams discover application weaknesses by running controlled fault injection experiments. It provides pre-built failure scenarios, automatic safeguards to prevent unintended impact, and monitoring integration to track application behavior during tests.

Independently observed

Toxiproxy

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.
