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.
Defrag98 opens in a browser tab — no download.
Not sure how to add Defrag98 to your home screen? Step-by-step for Chrome, Safari, Firefox and Edge — it takes about ten seconds, and there is no app store involved.
