...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.

...The tool helps developers monitor JavaScript memory behavior directly inside a web page during development or debugging. It works by creating a MemoryStats instance, adding its display element to the DOM, and updating it regularly with requestAnimationFrame. For more precise results, Chrome should be launched with the precise memory information flag, because default memory values may be bucketed. The project is useful for performance debugging, visual memory monitoring, and quick inspection of memory behavior in browser-based experiments.
