Argon Client — questions, answered
Argon Client FAQ: what the client does, how to open the menu, what to install, supported Minecraft versions and whether it is free.
What is Argon Client?
Argon Client is a Meteor Client addon for DonutSMP. It adds 90+ modules that do not ship with vanilla Meteor, tuned for the server's anti-cheat.
How do I open the Argon GUI?
Press Right Shift in game. Argon uses the Meteor GUI with an added search bar, profile import and export, and per-server config switching.
What do I need to install?
Fabric Loader, Fabric API and Meteor Client. OpSec is recommended to reduce detection risk on DonutSMP.
Is there a paid tier?
No. Argon is free, with no key system, no Discord verification and no paid tier.
Which Minecraft versions are supported?
The current Argon Client build targets Fabric 26.2, with a Fabric 1.21.11 build kept available for players on the previous release.
How often is the fly bypass updated?
The fly config is re-tuned against DonutSMP's anti-cheat profile regularly, usually within a day of each server update.
