VolumeGlass is a beautifully crafted macOS utility that reimagines how you control sound on your Mac. Inspired by the clean, glassy interface of iOS, it brings a modern, minimal, and delightful volume experience to macOS — all while staying lightweight, native, and completely open source.

VolumeGlass replaces the default macOS volume popup with a slim frosted glass overlay that lives on the edge of your screen and fades away when you're done. You can drag the bar to set volume precisely, double-tap to mute instantly, and long press to switch audio output devices. The app also allows you to choose from 5 screen positions and resize and reposition from settings.

The app uses CGEventTap to intercept the media keys so the system popup never shows, and replaces it with a native SwiftUI glass overlay. This technical approach ensures seamless integration with macOS while providing a modern user interface experience.

VolumeGlass provides benefits including precise volume control, instant mute functionality, and easy audio device switching. It stays lightweight on system resources, using almost no CPU (less than 0.5% CPU) and almost no memory, making it ideal for daily use without impacting system performance.

This utility is designed for macOS users who want a more elegant volume control experience. It's completely open source, allowing users to inspect the code and modify it if desired. The app integrates natively with macOS media keys and audio systems.
