About HydraPaper

HydraPaper is a wallpaper manager for Linux desktops that supports multi-monitor setups. Users add folders to a wallpaper collection, enable or disable those folders, and mark favorite images for quick access. Wallpapers can be set as zoomed, centered, or fitted, with either a black background or a blurred version of the image behind them. Random wallpaper selection is available, including from the app launcher.

Most GUI actions can also be performed from the command line, which the homepage describes as useful for custom scripts. The homepage lists installation through Flathub, the Arch User Repository, Fedora, and Debian (unstable). It describes HydraPaper as written in Python 3 and GTK, and as free software released under the GPL3 license, with source code on GitLab. The homepage does not state pricing.
