TreeMap-Disk Visualizer

free open-source disk space visualizer for Mac/Windows/linux

What it does

Blaze through storage clutter with an ultra-fast, 8-way concurrent directory walker that scans 500k files/min. Visualize your drive with a squarified treemap, drill into folders, and filter by globs like node_modules. Smart cleanup safely targets Xcode and browser caches, while a staged SHA-256 duplicate finder only hashes what it needs to, saving your CPU. Track storage growth over time with Trends + Compare views. Best of all, everything goes to the Trash—nothing is ever hard-deleted.

Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
