Hi HN,OP here. I built HardwareTest.org because I was frustrated with existing testing tools that required downloading executables or were filled with ads.It's a pure static site (hosted on Vercel) that runs entirely in the browser.Features:Keyboard Test: Includes a real-time Hz polling rate dashboard (I had to fight the browser event loop to get this somewhat accurate).Dead Pixel Fixer: Uses Canvas to generate high-frequency RGB noise.Mouse/Audio: Standard diagnostic tools.I used AI (Vibe Coding) to help build parts of it, which was an interesting learning experience regarding the limitations of AI in handling precise hardware events.Would love to hear your feedback on the accuracy, especia

Within the show hn launch space, the company focuses on its core offering rather than a broad product line.

Its current recorded stage is Show HN launch.
