Hackable HTTP proxy for resiliency testing
Toxy is a programmable HTTP proxy created for resiliency testing and simulation of unreliable network conditions. It operates at the HTTP application layer, giving developers more control over requests and responses than basic TCP throttling tools. Its core model uses poisons to alter traffic and rules to decide when those alterations should apply. Tests can inject latency, limit bandwidth, return errors, manipulate payloads, or combine several adverse conditions.
