How these are built
Every tool runs entirely in your browser using standard Web APIs — no data leaves your machine. The "What laptop am I on" tool, for example, reads the browser's user-agent string, the WebGL renderer string, and the device-memory hint, then translates those into plain English. The "refresh rate" tool counts frames over one second using requestAnimationFrame.
