Changing the meaning of speed

Delta Client has 3x higher fps, 2.5x lower cpu usage, starts faster than the Minecraft launcher and loads chunk as smooth as butter. Lag will no longer be an excuse for a lack of skills.

A sleek and intuitive UI

Delta Client's UI was designed to feel right at home on macOS. It's powered by SwiftUI which allows the client to have extremely low resource usage when not in-game.

Quick to install

Just download the app, open it, wait a minute or two, login, and you're ready to go! Yep, it's really that simple.


There are many ways to contribute to Delta Client. Any help with developing the client, the website or Swift Bundler is always greatly appreciated.
