Modding has become a vital part of the gaming experience, allowing players to enhance gameplay, add new features, or completely transform a game. For players of popular titles like Risk of Rain 2, Valheim, or Lethal Company, the Thunderstore Mod Manager (TMM) is one of the most reliable tools available. If you’re new to modding or just looking for the best way to manage mods safely, this guide will help you understand everything about the Thunderstore Mod Manager.

What is Thunderstore Mod Manager?

Thunderstore Mod Manager (TMM) is a free and open-source tool designed to make modding simple and safe. It is the official mod manager supported by the Thunderstore platform, which hosts mods for dozens of games. With TMM, players can install, update, and manage mods with just a few clicks, eliminating the hassle of manual downloads and file replacements.

Instead of manually editing game directories, TMM creates separate modded profiles, ensuring your base game files remain untouched. This makes modding much safer and allows you to switch between modded and vanilla versions of the game easily.
