Harbofly is a free, open-source menu bar app (plus CLI) that finds the gigabytes dev tools hide: DerivedData, node_modules, Gradle, Homebrew caches, even LLM weights from Ollama, and frees them safely: risk tiers, Trash-first, source code never touched. It spots idle projects via your local git (warning about unpushed work), explains macOS "purgeable" space, auto-cleans on your terms for free, where alternatives charge $29, and speaks 6 languages. No account, no Pro plan, opt-in telemetry.
