MuGen Wallpaper vs Palace

MuGen Wallpaper is a macOS desktop app for dynamic video and programmable web wallpapers. It supports multiple screens, and web wallpapers can receive system utilization and screen-index information. Video speed and volume controls are included in both tiers. Playback can pause when every screen is in fullscreen mode, and the app can launch at startup. The maker says video playback uses Apple Silicon for efficient playback and lower power consumption. The MuGen Wallpaper Community lets users download and share wallpapers, with uploads reviewed before publication. Web wallpapers may opt into weather updates through OpenWeatherMap, using a supplied API key and location access, but they are limited to local resources and cannot call external APIs directly. The free plan costs nothing and allows up to 10 dynamic wallpapers. An unlock is a one-time in-app purchase with no listed price and no wallpaper limit. Community registration collects an iCloud identifier and associated Apple ID email; tokens and the weather key are stored in Keychain.

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.
