Clockwork Orange vs Wallpaper Cycler

Clockwork Orange manages desktop wallpapers on KDE Plasma 6, Windows 10/11 and macOS 13+. It can select random images from local folders, distribute choices fairly among sources and assign a different image to each monitor. On KDE Plasma, it can rotate the lock-screen image separately from the desktop. Download plugins fetch images from Wallhaven and DuckDuckGo Images on hourly, daily or weekly schedules, with a file limit configurable for each source. Wallhaven’s full catalogue requires an API key. The app records image URLs and content hashes to prevent duplicate downloads, even if a file has been deleted. Marking an image in the window deletes the file and adds its hash to a blacklist for future downloads. Version 4 is a native Go program with a command-line binary that also runs as the daemon, plus a Fyne desktop window with plugin controls, history, blacklist management and settings. It is free under the MIT License. On Linux it can run as a systemd user service; the macOS app is ad-hoc signed and not notarised.

Wallpaper Cycler is a Windows desktop wallpaper manager that changes images after a delay or at specified times. It organizes wallpapers in multilevel categories, which can have time constraints and link to folders to detect new images. Layouts can place calendars, quotes, notes, webcams, other wallpapers, calendar notes, and RSS headlines on the desktop. The software supports more than 20 image formats, including JPG, BMP, TIFF, PNG, GIF, and JPEG 2000. Its random selector uses all wallpapers before repeating one. The maker says it can manage tens of thousands of wallpapers and pause cycling when CPU load is too high. Effects can be extended with third-party DLLs using the included SDK, and third-party control is available through WPCController in version 3.6. Wallpaper Cycler Lite is free; the full single-user version costs $19.95, paid once, with tax not included. A site license costs $495 as a one-time purchase. The trial is limited to 30 runs and does not allow layouts to be exported. Listed system requirements cover Windows XP, 2003, Vista, and 7, excluding Windows 7 Starter.
