Burrow

Burrow is an independent open-source (MIT) app. It bundles its own engine — burrow-engine, a single source-available binary under the Functional Source License (FSL-1.1-ALv2) whose command surface is modelled on the Mole (mo) CLI by tw93 — and is not affiliated with or endorsed by mole.fit (the official Mole for Mac app by mo's author); its own name, mark, palette, and copy are original.

If you like Mole and want to fund mo's development — buy mole.fit ($19).

burrow 🐹 The open-source system companion for your Mac — clean, uninstall, analyze, optimize, and monitor, built for you and your AI agents.

Burrow puts everything your Mac needs in one free, native app: junk cleanup, dev-artifact purge, app uninstall with leftover removal, duplicate finding, safe maintenance, disk maps, and live system status — powered by one bundled engine binary (burrow-engine, FSL-1.1 — see Attribution) whose commands mirror Mole's mo, so there's nothing else to install. It keeps months of local metric history and runs a built-in MCP server, so AI agents like Claude Code, Codex, and Cursor can watch, query, and care for your Mac — actions are consent-gated and audited, and Trash-based removals remain recoverable until the Trash is emptied. Permanent deletion requires separate consent and cannot be undone. Native on macOS, with a Windows preview under windows/.

Mac:

brew install --cask caezium/tap/burrow

Windows: download from releases

Explain with AI — point an MCP-capable agent (Claude Code, or a local model via LM Studio) at Burrow and ask your Mac in plain language.

When doing other tasks with AI Agents, if they find something irregular with your system, for example low disk space, they will have the tools to automatically disect the problem, and perform secure cleanups for you proactively and autonomously, without you having to ask.
