Transom – Safe Disk Cleaner for macOS Developers (Open Source, Go)

My role: Creator & Maintainer

Open-source disk cleaner for macOS, built for developers. Scans system junk, Xcode DerivedData, package-manager caches (npm, Composer, pip, Go), Docker build cache and stale node_modules/vendor folders, then lets you clean item by item. Safety-first design: read-only scans, per-item risk levels, Trash by default, a path guard that blocks anything outside $HOME, and commands from a fixed allowlist. One Go binary with an embedded web panel inside a native AppKit app, plus a CLI, cleanup history and dry-run estimates.
