A free, open-source macOS utility by Erwin Bonsma that graphically shows disk usage as a treemap, released under the GNU General Public License and downloadable from SourceForge, with a paid Mac App Store copy that funds development. grandperspectiv.sourceforge.net · Free from SourceForge; $2.99 on the Mac App Store for the same app

GrandPerspective is free and open source, and this app is neither. That is the most important line on the page, so it goes first. It has been developed by one person since 2005, the source ships alongside every release under the GPL, and the $2.99 Mac App Store copy is explicitly the same app — the author charges it to cover the developer-programme fee, not to gate anything.
It is also more capable than its reputation suggests. Version 3.8.0, released on 24 August 2026, colours the treemap by any of ten different properties including file type, folder depth, size and last-access time; filters on name, path, size, type, hard-link status and package status, and can use those filters to mask files, hide them, or exclude them during the scan; handles hard links so Time Machine backups analyse correctly; saves a scan to reload later; exports as image or text; and lets you re-scan to compare a view before and after a clean-up. Anyone describing it as "just a treemap" has not opened the filter panel.
Where Dropit differs is breadth on both axes. GrandPerspective has one visualisation, tuned over twenty years. This has eight — treemap included — because a size question, an age question and a "many small files" question do not have the same right picture. And it has a cleanup layer GrandPerspective does not attempt: a Quick Wins catalogue, duplicate detection by content hash, an app uninstaller that chases leftover support files, and a safety tier with a written reason attached to every item before it can be staged for deletion.
The pricing comparison is narrower than free-versus-paid makes it sound. Scanning and all eight views here are free forever, with no time limit and no account, which is the same job GrandPerspective does. Payment unlocks the cleanup half. So the real question is whether the cleanup half is worth $3.50 to you — and if it is not, GrandPerspective is an excellent tool and you should use it.
One last thing worth stating plainly, because it is not a small advantage: GrandPerspective is auditable. You can read the source of the thing you are about to point at your home directory. Ours is not open source, and no amount of documentation is the same as source you can read.
Choose GrandPerspective if what you want is a treemap of your disk so you can spot the big rectangles and delete them yourself. It does that well, it costs nothing, you can read its source, and it has been maintained for twenty years — if that is the job, there is no reason to pay us. Choose it also if you need hard-link-correct analysis of a Time Machine volume, or filters more precise than ours.

Choose Dropit if the treemap has stopped answering your question — if the space is scattered across caches, duplicates, app leftovers and build artifacts rather than sitting in a few large rectangles — or if you want a written safety reason attached to each item before you delete it. Scanning and all eight views are free permanently, so you can compare the viewing halves side by side and only pay if the cleanup half earns it.
It is open source under the GPL with the source published alongside each release, it has been maintained by the same author since 2005, and a copy is distributed through the Mac App Store, which means it has passed Apple review. As with any tool that can delete files, ours included, the thing to check is that you can see the full path of what you are about to remove — GrandPerspective shows you the file in the view before you delete it.
The SourceForge download is free. The author also sells it on the Mac App Store for $2.99 and states it is the same app — the fee covers the Apple developer programme and development costs, and buying it adds automatic updates and Apple review. Nothing is withheld from the free copy.
It is a disk usage visualiser and does not set out to be a cleaner: there is no duplicate finder, no application uninstaller and no curated catalogue of caches or developer artifacts. Deletion is manual, item by item, from the treemap.
It is if you want more than one view of the same scan, or if you want the cleanup half — duplicates, uninstalls, caches and build artifacts with a safety reason on each. It is not if you specifically want free, open-source software, in which case GrandPerspective remains the better answer.
