Where WizTree wins
It has been on Windows for years, its home licence is free, and on an NTFS drive it reads the Master File Table directly.
Where Leita wins
Linux, alongside Windows and macOS. Saved scans you can compare, so a treemap coloured by change shows what grew since last time. Reports in PDF and HTML as well as CSV and JSON. Reclaim, which names build output and caches with a reason for each suggestion. Source available, and nothing leaves your machine.
Folders as rings around the root; the largest arc is where to look first.
Which to choose
Already on WizTree, on one Windows machine, with nothing to compare and no one to report to: stay. Otherwise Leita: free at home and at work, on Linux as well, with a history that shows what changed and a report to hand on.
WizTree is free at home and licensed for commercial use from $100. Leita is free at home and at work; Pro is $39 a year for one person and $99 for commercial work.
