GUI disk analyzers are great for figuring out what's filling up your laptop/desktop drive. On containers or remote servers, the options are limited to purely text based utilities (e.g. du) or list-centric TUIs (e.g. ncdu) which are usually limited to viewing one directory at a time. I created leaves to fill that gap. Inspired by classic utilities like WinDirStat and KDirStat, it uses a 2-dimensional treemap^1 visualization to show the entire directory hierarchy with proportionally sized rectangles. It's performant enough to handle millions of files, thanks to Rust and multi-threading.…

FreeUpMyMac▲110Hey HN Ex YC/Google engineer turned indie maker here - excited to share something I just shipped. The System Data in my Mac was taking up 300GB and it took me months to figure out how to clear the old cache, logs, junk and more. And CleanMyMac is a subscription - I refuse to pay subscription fees for Mac apps that run locally. So I built FreeUpMyMac an offline, lifetime Mac cleaner that clear junk with 1 click. And helps you visualize your storage with TreeMap/Sunburst. Hope it’s helpful to you as it is for me. Would love your feedback Tunde

I like treemaps for visualizing hierarchical mass and density of resource usage. I've always particularly loved GrandPerspective's dense, colorful rendering, but haven't found a similar but generalized treemap that works in reactive web views across many data visualization contexts. So I built gp-treemap, a canvas-based web component that renders GP-style treemaps with millions of nodes: https://github.com/imbue-ai/gp-treemap/ If you want to give it a spin, try something like this command to visualize hierarchical disk usage: npx -p @imbue-ai/gp-treemap gpdu…

Room Service▲128Built this after repeatedly running into “Disk is full” on macOS with no clear explanation. Started as a cleanup tool for dev environments (Xcode, Docker, node_modules), but the harder problem turned out to be understanding what’s actually taking space. macOS groups a lot of this into “System Data”, which isn’t very actionable. Recently, local AI tools made this worse. Model files and caches (Ollama, Hugging Face, Whisper, etc.) grow silently and are spread across different locations. The goal is to make disk usage more transparent before deciding what to remove. Would appreciate feedback,…
