Palace vs Walltone

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.

Walltone is a free GPL-3.0 wallpaper and theme manager for Linux. It handles static images, video wallpapers, and animated Wallpaper Engine content, with browsing and downloads from Pexels, Unsplash, Wallhaven, and Wallpaper Engine. Users can assign wallpapers per display, arrange monitor layouts, and adjust scaling. From wallpapers, Walltone generates light and dark Base16 and Material You color schemes; a color picker allows refinements and theme exports for other applications. Tag filters, search, sorting, Boolean filters, and a JavaScript-capable template engine support organization and customization. Video controls include mute and scaling. Wallpaper Engine controls include volume, FPS, audio, parallax, fullscreen pause, and texture clamping. Video or animated wallpapers can be captured as still images for login managers or GRUB. Online sources require API keys, including a Steam Web API key for Wallpaper Engine. Installation is listed through the Arch User Repository, a Nix flake, or source builds. Requirements include Linux, Node.js 18+, and playback and screenshot utilities.
