Open-source Mac cleaner

A clean Mac,
without the fuss.

HahaClean is the friendly desktop app for cleaning your Mac — sweep away caches and junk, uninstall apps completely, cool things down, and free up memory. One window, big buttons, nothing to learn.

Free & open source · macOS 14+ · Apple Silicon & Intel · 中文 / 日本語 included

A smiling broom sweeping sparkles toward a fresh, clean Mac

Built on the open-source Mole CLI — HahaClean bundles the engine and wraps it in a calm, novice-friendly interface. No Terminal required.

Everything in one calm window

One-tap cleanup

Scan first, see exactly how much you'll reclaim, then clean. Caches, logs and app leftovers — your in-use data is never touched.

Complete uninstall

Remove an app and everything it left behind — preferences, caches, launch items. Search, click, gone.

Fan control

Force the fans before a long, heavy session — for 15 minutes up to "keep going." Capped at your hardware's limit, auto-restores if the app quits.

Free up memory

See what's eating your RAM and reclaim file caches with one tap. Quietly, no reboot.

Stale dev environments

Find the nvm, pyenv, conda and Homebrew installs you forgot six months ago — and how much disk they're hoarding.

Disk & project slimming

Drill into what's filling your disk, and trash rebuildable node_modules/build folders — always recoverable.

Fully open source

HahaClean is free and open source under the GPL-3.0 license — every line, including the bundled cleaning engine. It's an independent project built on Mole (also GPL-3.0), and is not affiliated with or endorsed by the Mole project.

No telemetry. No tracking. No accounts. The app never phones home.
