IO-Client

Open Source • Community Driven

Let's cut to the chase.

IO-Client is a modern open source utility client for Minecraft. Built by developers and players who care about speed, control, and clean code.

Started as a small side project, IO-Client has grown into a transparent and extensible client with frequent updates from contributors around the world.

Built by devs who love open source.

IO-Client began as a collaboration between friends who wanted a cleaner, faster, and more customizable Minecraft experience. Over time, it evolved into a full open source project focused on stability, smart tooling, and user choice.

We believe users should know exactly what they run. That is why every major component is reviewed in public, documented, and tested by the community.
