LTK Manager is a Windows application for installing and managing custom visual modifications to League of Legends. In the League of Legends modding community, players create alternate skins, champion models, and visual effects for personal use. These files are packaged in a format called Fantome, and LTK Manager is the tool that injects them into the game at launch. The app presents your installed mods in a card-based library where you can enable, disable, reorder, and remove them without touching game files directly. It automatically locates your League of Legends installation through the Riot Client, applies the mods when you launch the game, and keeps backups of the original files so you can restore them. You can also save different mod combinations as profiles, which is useful if you want one setup for ranked play and another for casual games. The application is built with React for the user interface and Rust (via a framework called Tauri) for the underlying system operations, which keeps it fast and avoids the overhead of a full web browser runtime. Installation is straightforward: download the zip from the Releases page, run it as Administrator, and the app handles detection and setup. Two things to know before using it. First, this is a community-maintained fork, not an official Riot Games product. Custom mods may violate Riot's Terms of Service, so use it with that understanding. Second, because the tool patches game files, some antivirus programs flag it as suspicious even though the code is open source and available to inspect. The readme recommends downloading only from this repository, scanning files on VirusTotal, and adding a folder exception in your antivirus. MIT licensed.
