A Homebrew GUI for Mac

Casky is a Mac app for Homebrew. Browse every app and command-line tool Homebrew offers, install several at once, and keep them updated, along with your Mac App Store apps, from one list.

Browse the whole Homebrew catalog

Every formula and cask is in Browse, ranked by how often people install it (Homebrew's own install counts). Filter to apps, command-line tools or the App Store, or search by name or description. Before you search, Browse recommends popular apps and tools you don't have yet, starting with what's missing from the kits you use most.

Press Space on anything for its version, license, popularity and the commands it adds.

Install several at once

Tick what you want and choose Install. Casky downloads everything first, all at once, then installs each item. App Store apps install through mas alongside Homebrew instead of waiting their turn.

Some apps come as an installer package and need administrator rights. Casky marks them "Needs admin", asks for your password once and then confirms each one with Touch ID.

Every update in one list

Updates lists everything with a newer version: Homebrew apps and tools, App Store apps, and apps that update themselves. Choose Update All, or pick the ones you want. Hold keeps an app at its current version and out of Update All.

Casky checks every 4 hours while it's open, can show updates in the menu bar and notify you, and can upgrade Homebrew apps every morning even when it's closed.

Services, taps and clean up

• Start and stop Homebrew services, and choose which ones run at login.
• Add a tap to browse and install from it.
• Clean Up removes old versions, cached downloads and dependencies nothing uses, and tells you how much space you'll get back first.
• Installed lists everything Homebrew and the App Store put on this Mac. Uninstall from there, from any list, or with ⌘⌫.

Save it for your next Mac

Save This Mac turns what's installed into a setup you can apply on another Mac, or export as a Brewfile, an Ansible playbook or a nix-darwin flake. See setting up a new Mac.

Requirements

macOS 26 or later. If Homebrew or mas is missing, Casky offers to install it.
