...By averaging data across multiple page loads, Hiper helps developers understand whether performance optimizations actually improve real-world page loading behavior. The tool relies on browser performance timing data to capture metrics such as DNS lookup time, TCP connection time, time to first byte, download duration, DOM readiness, and total page load time. Hiper runs from the command line and can be installed globally using Node.js package managers, making it simple to integrate into development or testing workflows.

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. Rules can filter traffic by route, headers, query values, methods, bodies, and other request properties. ...
