WallFetch Engine is a command-line tool that downloads animated wallpapers from the Steam Workshop without needing the Steam application to be running. Steam Workshop is a platform where users share and download content, including animated desktop wallpapers compatible with tools like Wallpaper Engine. Normally, accessing Workshop files requires the Steam client to be open and running in the background, but WallFetch bypasses that requirement by communicating directly with Steam's web API. The tool can extract several types of animated wallpaper files, including MP4 and WMV videos, and Scene formats used by Wallpaper Engine, along with their associated textures and audio. Downloaded files are compatible with Wallpaper Engine, Lively Wallpaper, or custom desktop setups. The tool focuses on speed, using a technique called multiplexed concurrent downloading, through a library called libcurl, to download multiple assets at the same time rather than one at a time. You would use this if you want to save Steam Workshop wallpapers to your local machine for offline use, back up a collection, or move wallpapers to a different setup without relying on Steam's standard subscription and sync mechanism. It is available as pre-compiled binaries for Windows and Linux, so most users do not need to build it from source code. The project is written in C++20 and is licensed under MIT.
