Palace vs Waywallen

Palace is a personal media manager and wallpaper engine for organizing and displaying wallpapers and other media. You can sort items into categories, albums, and favorites, then search by name or tag. Display choices include fill, fit, center, tile, stretch, or spanning multiple monitors, with adjustable background colors and effects. Automatic rotation can run sequentially or in shuffle mode, at intervals from five seconds to several hours, and can target individual displays. Palace supports GIFs, video files such as MP4 and WebM, GLSL shaders, and locally stored images; desktop video wallpapers require MPV. Online sources use public JSON files and must provide direct public media URLs, not private or password-protected files. Local media works offline, and ordinary use does not require an account. Palace says wallpapers, preferences, and settings stay on the device and personal images are not uploaded or accessed. The web hub supports browsing community sources, downloading wallpapers, and submitting source URLs. A Palace lifetime license costs $4 as a one-time purchase; Google Play costs $7.99, paid once for Android only.
