VI Software

Welcome to VI Software

Tools for Minecraft Modders, by Modders

We’re a small team of Minecraft modders and server owners building open-source tools to make running and playing on modded servers easier.

What We Offer

Tool	What It Does
VIS Launcher	Lets you connect to VI Software servers, manage mods, and switch accounts easily. No manual updates, no hassle.
VIS Yggdrasil Auth	Your server auth stays online even if Mojang’s auth is down. We only connect to Mojang once to verify your game purchase, after that, everything runs on our own servers.
