Dim background windows. Focus on the one that matters.
OpenHaze highlights your active window by fading everything behind it into an adjustable haze, from a soft shade to a total blackout. An open-source recreation of HazeOver for macOS, plus a native Windows sibling that HazeOver never had.
Intensity from 0 to 100% with smooth crossfade transitions and a custom haze color.
Independent focus per display, or one lit display with the rest fully dimmed.
Menu bar and system tray slider. Scroll over the icon to adjust intensity.
Toggle the haze or nudge intensity up and down without leaving your keyboard.
Swift and AppKit on macOS (about 1,700 lines), C# and WinForms on Windows (about 1,400). Zero dependencies, builds with stock toolchains.
Fn-to-reveal gesture, separate Light and Dark settings, AppleScript and an openhaze:// URL scheme.
