Zen Mode brings a global focus overlay to macOS via a single menubar toggle

Zen Mode is an open-source macOS utility that dims everything outside your active window, helping you cut through desktop clutter without switching apps or spaces. It's a lightweight, system-wide solution aimed at developers and makers who want distraction blocking baked into their OS rather than relying on per-app focus features. For solo builders juggling multiple tools, a global focus layer that requires zero configuration is a practical quality-of-life addition.
