Homebrew, From Your Menu Bar

Brewster is a lightweight macOS menu bar app that keeps an eye on your Homebrew packages. See pending updates at a glance, upgrade individual formulae or everything at once, and install new packages — all without leaving the menu bar.

Features

Everything you need to keep Homebrew tidy

Menu Bar Integration

Lives quietly in your menu bar with a badge counter showing how many formulae and casks have updates waiting.

One-Click Upgrades

Upgrade a single outdated package or run the whole batch at once — no terminal required.

Install New Packages

Search for and install new Homebrew formulae and casks straight from the menu bar dropdown.

Automatic Checking

Configurable refresh intervals keep the update count current in the background, on your schedule.

Launch at Login

Optional auto-launch keeps Brewster running from the moment you log in — you’ll never miss an update.

Native & Lightweight

Built with Swift and AppKit for a snappy native experience that respects your CPU and battery.

How It Works

Update Homebrew without breaking your flow

2. Notify

A badge on the menu bar icon counts the packages with pending updates so you know at a glance.

3. Upgrade

Click any item to upgrade it, or run the whole batch with one click. Hold ⌥ for advanced options.
