OmniDiskSweeper
Sometimes we make software for us, and we love it so much we make it available to you, too. Quickly find large, unwanted files and sweep them into the trash. OmniDiskSweeper shows you the files on your drive, largest to smallest, and lets you quickly Trash or open them. OmniDiskSweeper 1.12 is our free app for finding disk space on your Mac, and we just updated it for Catalina (macOS 10.15)! It shows you everything on your hard drive, ranked by size, so you can see which files and folders are taking up a lot of space, which helps you figure out what you can delete, or move somewhere else, so you can free up disk space. The updates for Catalina include a Dark Mode About Panel, fixed handling of Catalina volumes, and removal of an unneeded notification. But do note that Catalina will ask for permissions for OmniDiskSweeper to access various things, it might ask, for instance, if it can access your contacts.

Robot Space
You’ll spend less time worrying about your disk space when your daily disk space monitoring is completely automated—and you’ll spend less money over the long run by better managing your objects and files, so you don’t purchase unnecessary, expensive extra disk. Understanding current trends within your storage environment gives you greater visibility to predict your organization’s disk space needs and plan for the future accordingly, thanks to the historical metrics visible in your disk space analyzer. Regular monitoring for everything from active jobs to spooled files using flexible storage thresholds helps you stay on top of disk space at all times, not just when you’re reaching capacity. Drill into disk storage problems to discover what’s eating away at your disk space. See historical disk growth metrics, compare against previous collections, and use cleanup tools for addressing obsolete objects and file reorganization.

Broomkit
Broomkit is a native macOS disk cleaner and app uninstaller built for transparency and safety. It scans the home folder across 16 categories — app caches, package caches, dependency folders, simulators, logs, duplicates, and more — showing every file with its full path before removal.
The free version includes a full disk scan, interactive Disk Map visualisation, large and old file finder, and path browsing — no account required. A one-time licence unlocks Reclaim and the App Uninstaller with residue cleanup.
Safety is central: all removals go to Trash, inferred items start unchecked, and no admin password is requested. Leftovers are matched by exact bundle identifier to prevent accidental deletion.
Developer machines are a focus, covering npm, pnpm, pip caches, Xcode DerivedData, simulators, and Docker data. Broomkit runs natively on macOS 14+ on Apple Silicon and Intel, is notarized by Apple, and requires no subscription.

Dusty
Dusty is a native macOS storage-cleanup application for developers and Mac power users. It scans a Mac for large or older files, browser caches, developer dependencies and build artifacts, WhatsApp media, and application support files left after apps are removed. Users can review identified items and storage details, request plain-language explanations powered by Google Gemini, and choose what to move to the macOS Trash for review. The software also provides a one-click application uninstaller, a tool for finding old downloads and installers, and specialized cleanup for developer folders such as node_modules and Xcode build data. Dusty describes its storage scanning as local and provides reversible Trash-first cleanup. It is distributed as a Mac app for Apple Silicon and Intel computers. A 24-hour full-access trial is available; paid options include a lifetime license for one Mac and a plan covering up to three personal Macs.
