Explore WailBrew: A Lightweight GUI for Homebrew Built with Go and React

Overview

WailBrew is an open‑source graphical management application for Homebrew on macOS. It provides a visual interface to list installed formulae, view dependency graphs, check for updates, install new packages and uninstall existing ones, and run Homebrew diagnostics without using the command line.

Architecture

The application is built with the Wails framework, which combines a Go backend with a React front‑end. Go handles Homebrew command execution and data processing, while React renders the UI in a lightweight Electron‑like window.

Key Features

Visual list of all installed Homebrew packages with version information.

One‑click “Check for updates” that queries brew outdated and displays available upgrades.

Install and uninstall operations executed via brew install and brew uninstall behind the scenes.

Dependency graph view that parses brew deps output to show direct and transitive relationships.

System diagnostics that run brew doctor and present warnings in the UI.

Batch update mode allowing selection of individual packages or updating all outdated formulae.

Package detail pane showing conflicts, required dependencies and optional build options.

Internationalisation with nine language packs (e.g., English, Chinese, German, French).

Supported Platforms

Runs on macOS 11.0 (Big Sur) and later, compatible with both Apple Silicon (ARM) and Intel CPUs.

Installation & Usage

To build and run WailBrew from source:

# Clone the repository
git clone https://github.com/wickenico/WailBrew.git
cd WailBrew

# Install Go dependencies (requires Go 1.18+)
go mod tidy

# Build the application (Wails will compile the React front‑end)
wails build

# Run the binary
./build/bin/WailBrew

After launching, the main window displays the package list. Use the toolbar buttons to check for updates, install new formulae, or open the dependency graph view.
