BioniX Wallpaper Changer vs Palace

BioniX Wallpaper Changer is a Windows app for managing desktop backgrounds with live video, slideshows, photo collages, animated effects, and automated changes. It accepts JPG, PNG, BMP, WebP, GIF, TIFF, and HEIC images, along with video, animated GIF, and animated WebP wallpapers. Playlists can be filtered by name, path, rating, or EXIF data, sorted, rated, monitored for folder changes, and batch-imported from webpages or Flickr. Wallpaper changes can follow local sunrise and sunset or specified times. On multiple monitors, each display can use its own mode, share one image, or clone the same wallpaper. The app can show webpages as wallpaper and apply AI border fill through local ComfyUI or SD WebUI/Forge, or cloud providers including Stability AI, Runware, OpenAI, Replicate, and fal.ai. It is portable, can run from USB without installation, and pauses animation during full-screen use or battery operation. Windows Vista through 11 are listed; macOS and Linux builds are not planned. A 15-day trial and free plan are available, with paid plans from €9.99 a year.

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.
