Where a developer Mac's disk space goes
Practical guides on the folders Finder never shows you: build products, package caches, container images and model weights. Each one names the owner, the path, and whether it comes back after you delete it.
How to free up disk space on a developer Mac: where the gigabytes actually hide
A developer's Mac fills up with Xcode DerivedData, node_modules, Docker images, Hugging Face and Ollama models, package caches and simulators. Here is where each one lives, how big it gets, and the exact command to reclaim it safely.

A reference table of developer folders on macOS sorted into three marks: R comes back on its own, I does not, P should never be touched. Covers Xcode, Docker, npm, pip, Homebrew, Hugging Face, Ollama, Gradle, Cargo, Go and editor caches.
Or let Latent map it for you
Latent attributes every gigabyte to the tool that owns it, marks each folder R, I or P, and only offers what it can prove is safe to remove.
