Frequently asked
Is this actually free?
Yes. Krypton, Radium, and 67 Client are all free to download and use — no paywalls, no "premium" unlocks hiding behind a price tag.
Do I need Fabric?
Yes. Every client here is a Fabric mod, so you'll need Fabric Loader and Fabric API installed before any of them will load. The Guides page walks through it step by step.
Are the files safe?
Every download listed is checked before it goes up, and links point to the original source rather than a mirror. If a checksum is provided on a client's page, it's worth verifying it yourself before running anything.
Will I get banned?
It depends on the server. Clients that only touch visuals or performance are fine almost everywhere; ones that add gameplay advantages can get you banned on servers running anti-cheat. Check what a client actually does before turning it on somewhere that matters to you.
Which Minecraft version is supported?
Minecraft 1.21.11 on Fabric — that's the only version all three clients target right now, so there's no guessing which build to grab.
How do I update a client?
Download the newest jar from that client's card and swap it for the old one in your mods folder. Same folder, same steps as the first install.
Can I request a client?
Yes — post it in the requests channel on Discord. Not every request gets added, but every one gets read.
Do you collect any data?
This site doesn't run analytics or trackers. The clients themselves are separate software, so check each one's own settings for what it collects.
How do I uninstall?
Delete the client's jar from your mods folder and remove any launcher profile pointing to it. Fabric API can stay — other clients on this site use it too.
