Dropit vs OmniDiskSweeper
Beide tools vinden grote bestanden. Hier zijn de verschillen — ook waar OmniDiskSweeper de betere keuze is.
A free Mac utility from The Omni Group that, in their own words, "shows you the files on your drive, largest to smallest, and lets you quickly Trash or open them" — a plain hierarchical list of sizes, published under their Omni Labs banner. www.omnigroup.com/more · Free

The first thing to say, and to say before anything else, is that OmniDiskSweeper is free and this is not. The Omni Group have handed out a genuinely useful tool for years and asked nothing for it, and if the free tool solves your problem then the free tool is the right answer. We would rather write that sentence than have you find it out after paying.
What it does, it does with almost no ceremony. You point it at a drive, it walks the tree, and it gives you nested columns of folders sorted largest to smallest. There is no chart to interpret and nothing to learn. For the single most common version of this problem — "something enormous is on this disk and I have no idea what" — you will usually have your answer before a graphical tool has finished drawing.
Dropit is the other shape of the same problem. It renders the same tree eight different ways — treemap, sunburst, flame graph, bubbles, folder cards, top sizes, age map and mind map — because "what is biggest" and "what is oldest" and "what is spread thinly across a thousand small files" are three different questions and a size-sorted list answers only the first. It then adds the half OmniDiskSweeper deliberately does not have: a Quick Wins catalogue, duplicate detection by content, an app uninstaller that chases leftovers, snapshots, and a safety tier with a written reason on every item before it can be staged.
On cost, the fair comparison is narrower than it looks. Scanning and all eight views in this app are free permanently, with no time limit and no account — the same job OmniDiskSweeper does, at the same price. What is paid here is the cleanup half, which OmniDiskSweeper does not attempt at all. So the honest question is not "free versus $3.50", it is "do you want the cleanup half, and is it worth $3.50 to you".
The current OmniDiskSweeper build is 1.16, dated September 2025, and Omni still publishes older builds going back to macOS 10.4 for people on old machines — which is a kind of care most software does not get.
Waar OmniDiskSweeper wint
- It is free, completely and with no upsell, and it has been free for years. We charge money for the cleanup half of this app, and no feature list changes the fact that zero is a better price than $3.50.
- It is faster to an answer than anything with a chart in it. Open it, pick a drive, read the top row. There is no view to choose, no legend to decode and no onboarding.
- It is tiny — about an 8 MB download — and it comes from The Omni Group, a studio with a thirty-year reputation on the Mac that they are not going to spend on a free utility.
- Omni still publishes builds for macOS versions going back to 10.4, so it runs on hardware that nothing else in this category supports. We require macOS 14 or later.
- Because it only lists and Trashes, there is very little it can do wrong. A tool with a cleanup engine has a larger blast radius by construction, and ours is no exception.
Choose OmniDiskSweeper if you want to find the one big folder and delete it yourself — it does that quickly, it costs nothing, and there is no honest argument for paying us instead. Also choose it if you are on an older macOS than 14, or if you simply prefer a text list to a picture.

- Eight interactive views of the same scan, so you can see a directory that is large because of one huge file differently from one that is large because of forty thousand small ones.
- A cleanup half that OmniDiskSweeper does not attempt: Quick Wins, duplicates matched by content rather than name, an app uninstaller that sweeps leftovers, and a developer catalogue covering Xcode DerivedData, simulator runtimes, node_modules, and the npm, pnpm, cargo, Go, pip and Homebrew caches.
- A safety tier and a plain-English reason on every item before it can be staged — "regenerable cache, Chrome rebuilds it" — plus a refusal to stage protected system paths at all.
- An age map that answers "what is large and untouched for a year", which a size-sorted list cannot express.
- Snapshots, so you can scan today, clean, and see exactly what changed next month.
- Every view running as an interactive demo on this site, on a realistic dataset, before you download anything.
Choose Dropit if a size-sorted list has stopped being enough — if the space is spread across caches, duplicates, old app leftovers and build artifacts rather than sitting in one obvious folder, or if you want a written reason attached to each thing before you delete it. Scanning and all eight views are free here too, so you can compare the diagnostic halves without paying.
Vragen
Is OmniDiskSweeper still supported?
It is still published and downloadable from The Omni Group under their Omni Labs banner, and the current build is 1.16, dated September 2025. It is a stable, finished tool rather than one under active feature development, and Omni also keeps an archive of older builds for macOS versions back to 10.4.
Is OmniDiskSweeper free?
Yes. The Omni Group publish it free of charge and describe it as their free app for finding disk space on a Mac. There is no paid tier and no upsell.
What is the best OmniDiskSweeper alternative with a treemap?
GrandPerspective is the free, open-source treemap option and is a fair straight swap. If you want more than one visualisation plus the cleanup side — duplicates, uninstalls, caches, build artifacts — that is what this app adds, with scanning and all eight views free permanently.
Why pay for Dropit when OmniDiskSweeper is free?
For finding the largest folder, you should not — use the free tool. Payment here buys the cleanup half: duplicate detection by content, app uninstalls with leftovers, the Quick Wins catalogue, snapshots, and a safety reason on every item. The scanning and viewing half is free permanently in both.
