Practical, command-by-command guides to the gigabytes your dev tools hoard — written by the developer of DevCleaner. No fluff, real commands, honest risk labels.
Where every major toolchain hides its cache — Xcode, npm, Homebrew, Gradle, pip, Cargo, Docker — and the exact command to clean each one safely.
DerivedData, simulators, DeviceSupport, archives: what each folder costs to delete, plus the one pitfall that breaks builds.
Claude, Cursor, Windsurf, Ollama, LM Studio — caches vs. model weights, what's safe, and the session files you must never touch.
Package-manager caches, the global pnpm store, and how to hunt down forgotten node_modules folders sorted by size.
DevCleaner vs CleanMyMac vs DaisyDisk vs OmniDiskSweeper — three different kinds of tool, and when each one is the right answer.
