Field notes
The test directory is organized around hardware categories, with individual entries describing the action and result—for example, moving a set distance to measure mouse DPI or holding several keys to check rollover and ghosting. Its controller listings name PS5, Xbox, PS4, Switch Joy-Con, and PC pads. The homepage says the tests need no installation and that device data stays local, while noting that a few tests can share an anonymous score.
