Where WinDirStat wins
Its source is open under the GPL, where Leita’s is available to read under its own licence. It has been on Windows for years, with CSV and JSON export and a command line.
Where Leita wins
Linux and macOS as well as Windows. Comparison between scans, with the treemap coloured by what grew and what shrank. PDF and HTML reports. Reclaim suggestions with a reason each, and a log of every deletion. A sunburst and an icicle view beside the treemap.
Folders as rings around the root; the largest arc is where to look first.
Which to choose
Already on WinDirStat and wanting nothing beyond its treemap: stay. Otherwise Leita, also free at home and at work, with the same treemap beside a sunburst and an icicle, a history that shows what changed, Reclaim, and a report to hand on.
WinDirStat is free for any use. Leita is free at home and at work; Pro is $39 a year for one person and $99 for commercial work.
