Defrag98
Defrag98 recreates the Windows 98 Disk Defragmenter in your browser, down to the window chrome and the bitmap fonts. Pick one of four drives, press Start, and watch the cluster grid sort itself out to the sound of a grinding hard disk. It touches no real files. Installs to your home screen from any modern browser — no app store, no download; its manifest declares standalone display with a 512px icon, and its service worker caches assets for offline use. Submitted by its author and measured on 2026-08-31.
