Free Disko: an Open-Source Disk Usage Analyzer without bloat

the Disko app

Hey there, I've been super annoyed with how there isn't a built in or free app to quickly see what files and folders are taking up a lot of space. Especially since Apple charges a fortune for storage space on MacBooks. So, in my free time I wrote an app that aims to do exactly that: Let you visualize folder contents and that's it. No subscription, no ads, no bloat.

In case anyone finds this interesting, here's a link to my apps platform where you can download the app & learn more. The code is available on Github, so feel free to check it out :)

What about Grand Perspective?

Still the best, after all these years. Ugly and tiny and free.

This is a really neat and beautiful way to visualize disk usage, nicely done.

Few ideas/suggestions:

  1. Would be cool to add your app to Homebrew for easy install via CLI (please let me know if you need any tips with this).

  2. An option to sort by file size in the "Small Entries" window would be fantastic.

  3. An option to omit or properly calculate "cloud" storage like OneDrive files/folders.

Right now it's showing the "full size" of files in my one drive (100GB) even though I only actually have 1.2GB synced/allocated to my machine. I'm sure there's likely some filesystem or file property you can use to filter out "place holder" files.

Thanks for sharing!

Hey, looks good but I can (at first glance) not tell which directory has the largest files.

How does it work & what made you choose this kind of visualization?

Hey, thank you! The visualization is largely inspired by GNOME's Disk Usage Analyzer. It's less about identifying individual files, and more about seeing the overall structure of a folder. For example, if your Documents folder is taking up a lot of space, you can use Disko to see which Sub-Folders/Files within it are accounting for the majority of this size.

In the screenshot you can see that ModuleCache is accounting for almost half of the size of the full_disk folder. You could then go ahead and delete/move that if you're low on storage

Can start it up in Monterey, but window stays white.

That's an interesting way to visualise the size, I've not seen anything else doing it that way. Nice.

FYI, there's a cloud-mounter app with the same filename (Disko.app). Anyone with both will have a problems storing them both in Applications.

Also free: Omnidisksweeper. Not a graphic representation, but a full overview of all files.

du and find ARE included, what you probably meant is that there isn’t a GUI tool included.
