GUI wallpaper setter for Wayland and Xorg window managers on Linux. It works as a frontend for popular wallpaper backends like swaybg, swww, wallutils, hyprpaper and feh. Developed by Roman Anufriev since 2023.

Waypaper comes with the usual fill/fit/stretch options included and is particularly useful when testing out wallpapers so that one does not have to write a new command for every CLI tool every single time.
