Installation

Setup in five steps

Don't skip step 4 — it's not optional.

⚠️
Don't skip OpSec — you WILL get banned without it.
Make sure you install OpSec alongside Radium Client. It bypasses anticheat detection and keeps you safe on DonutSMP. No OpSec = instant ban risk.

Why choose us

Why pick Radium over the rest?

Other clients weren't built for DonutSMP. Here's what they leave on the table — and what Radium delivers instead.

vs Krypton
Solid — but stuck in time
  • Decent overall client
  • Modules detected
  • No longer updated
vs Meteor
Looks fine. Gets you banned.
  • Instant detection
  • Modules detected
  • Outdated for DonutSMP
  • Generic UI focus
vs Glazed Client
A bolt-on, not a client
  • Just a Meteor addon
  • Mid module quality
  • Outdated
Radium Client
The choice is obvious.
  • Built ground-up for DonutSMP
  • 95+ tuned modules
  • Active development
  • OpSec-ready out of the box
