LTK Manager

LTK Manager is the frontier mod manager for League of Legends. Install custom skins, HUDs, maps, audio and much more. One of the main goals is to support mods so they work indefinitely without breaking between patches. It is the League Toolkit team's successor to cslol-manager.

If you make mods, the built-in Workshop is where you browse the game's files, edit your mod and pack it, without leaving the window.

Download

1. Get the latest installer from the Releases page.

1. Run it and open LTK Manager.
2. On first launch the app looks for your League of Legends installation. If it cannot find

After that, updates take care of themselves. The app checks for new versions and shows you what changed before it updates.

LTK Manager runs on Windows 10 and 11 (64-bit). macOS and Linux are planned, but not available yet.

Install a mod

1. Download a mod as a .modpkg or .fantome file.
2. Drag it onto the LTK Manager window, or press Import (Ctrl+I) and pick the file.
3. Turn the mod on and press Start. Then launch League the way you always have, and your

Import sits on the library toolbar and takes a .modpkg or .fantome file.

Install from a link

A mod site can offer an Install with LTK Manager button. Clicking it opens the app and installs the mod for you. The first time a link comes from a site you have not used before, the app asks before it trusts the site.

A link from a new site asks first. Trusting the site lets its links install from then on.

The sites you trust are listed under Settings > Library, where you can remove one again.

Launching League

Out of the box, Start runs the patcher and nothing else. You launch League from the Riot Client as usual, and the patcher applies your mods when the game loads. This is the flow every cslol-manager user knows, and it depends on nothing outside the app.

Switch Launcher flow to Modern under Settings > General and the button becomes Play. One press builds your mods, starts the patcher and asks the Riot Client to launch League. The status bar follows each step, so a Riot Client that takes a few seconds to appear never looks like a hang, and it keeps following the game once it is up. The menu beside Play launches League on its own, without patching, and closes the game through the Riot Client while one is running.

Two settings go with the Modern flow:

• Hide Riot Client on game start sends the client's window to the tray once the game is up.
• Stop the patcher when the game ends stops it with the game. It is off by default, so you

The Modern flow is still marked experimental. When the Riot Client refuses a launch, the app says why and what to do, and Classic is one setting away.
