Automatic blue-light filter for Hyprland, Niri, and everything Wayland
Installation | Quick Start | Configuration | Commands
Sunsetr is an automatic blue-light filter for Wayland compositors. It automates smooth color-temperature transitions from neutral to warmer tones, designed to reduce eye strain and improve sleep. Sunsetr automatically adjusts your displays based on your geolocation or a clock-based schedule. It can also be used to persist the same color-temperature and gamma indefinitely and can alternate between various user-defined presets. The controller can integrate with and automate changes in your shell or UI applications via IPC.
