How to Download and Install Neodisk

Neodisk is available as a direct download for Mac (both Apple Silicon and Intel) and Linux, and Mac users can also install it via Homebrew with brew install --cask neodisk. If you want to try the interface before committing to an install, the site offers a web demo you can open in your browser first. All of these options come from the official Neodisk site, and the app is described there as private, free, and open source.

Before you start

A few things worth knowing so you pick the right path:

• Platform matters. The download page lists separate builds for Mac (Apple Silicon), Mac (Intel), and Linux. Picking the wrong Mac build will either fail to launch or run under translation, so check your chip first.
• Homebrew is Mac-only. The brew install --cask neodisk command applies to macOS. Linux users should use the direct download.
• No account or payment step is mentioned on the site, but don't assume anything beyond what's stated — the page simply presents downloads and the web demo.
• The app is read-only by design. Per the site, it never deletes your files, so installing it doesn't put your data at risk from the tool itself.

Check which Mac you have

1. Click the Apple menu in the top-left corner.
2. Choose About This Mac.
3. Look at the Chip or Processor line:
   • "Apple M1/M2/M3…" → Apple Silicon build.
   • "Intel Core…" → Intel build.

Option 1: Direct download (Mac and Linux)

1. Go to the Neodisk website.
2. Find the download section, which lists Mac, Apple silicon, Mac, Intel, and Linux.
3. Click the entry matching your machine.
4. Open the downloaded file and move or run the app as your platform expects.

Expected result: Neodisk launches and presents its scanning interface, where you choose a disk or cloud drive to analyze.

Common snags:

• On macOS, a downloaded app from outside the App Store may trigger a Gatekeeper warning the first time. You'll need to confirm you want to open it.
• If the app won't start on a Mac, you most likely grabbed the build for the other chip architecture — go back and download the correct one.

Option 2: Homebrew (Mac only)

If you already use Homebrew, this is the fastest route and keeps updates manageable.

brew install --cask neodisk

What happens: Homebrew fetches the Neodisk cask, downloads the app, and places it in your Applications folder. When it finishes, launch Neodisk like any other Mac app.

Common snags:

• If brew isn't recognized, Homebrew isn't installed or isn't on your PATH — install Homebrew first.
• If the cask name isn't found, your Homebrew index may be stale; run brew update and try again.

Option 3: Try the web demo first

The site includes a Web demo link alongside the downloads. Opening it lets you see how Neodisk visualizes disk usage — the interactive treemap and sunburst views — without installing anything.

This is the right choice if you're still deciding whether the tool fits your needs, or if you're on a machine where you can't install software. Note that a browser demo is a preview of the interface, not a substitute for scanning your actual drives, which requires the installed app.

Which option should you pick?

After installing

Once Neodisk is running, point it at a disk or cloud drive and let it scan. The results appear as a treemap and a sunburst view, both interactive, so you can drill into what's consuming space. Because the app is read-only by design, you can explore freely — it won't delete anything on its own.
