toxiproxy

Toxiproxy is a framework developed by Shopify for simulating network conditions. It acts as a TCP proxy, enabling developers to deterministically tamper with network connections in testing, CI, and development environments. It supports adding latency, limiting bandwidth, simulating connection drops, or timeouts. Through its HTTP API or various client libraries, applications can be configured to route connections via Toxiproxy, allowing controlled validation of application resilience and ensuring stability against network failures, thus preventing single points of failure.
