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 (opens in a new tab) (mo) CLI by tw93 — and is not affiliated with or endorsed by [mole.fit](https://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](https://github.com/caezium/burrow-engine), FSL-1.1 — see [Attribution](#attribution--license)) whose commands mirror [Mole](https://github.com/tw93/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/`](windows/).

The tools

Burrow wraps its bundled burrow-engine binary in a native desktop app: clean junk, purge dev artifacts, sweep leftover installers, uninstall apps, run safe maintenance, map your disk, and watch live system status — in one window. On top of that it adds things the CLI doesn't have: a long-running history of your machine's metrics in a local store and an MCP server so any AI agent (Claude Code, Cursor, Codex…) can ask "what's been happening on this machine."

macOS is the mature flagship. Windows currently has a native WinUI 3 / .NET 8 preview app, Windows telemetry/history, tray HUD, loopback HTTP, MCP stdio bridge, CI, tests, and unsigned release packaging.

Every scan offers a no-risk preview (--dry-run) first, a clear reclaimed-space summary when it finishes, and a Stop button to abort a
