Early access questions.

Is early access free?

Yes. The launcher and the in-game client are free to download and use. You need your own Minecraft Java Edition account to play online.

When is the full version?

It is planned for November 2026. There is no exact release day yet, and plans can change. The date will be announced on this site, in the Discord and in the RSS feed.

Which Minecraft version does the in-game client support?

Minecraft 1.21.1 on Fabric with Java 21. The launcher can start other versions, but they run without the FireClient mod.

Will updates delete my worlds?

No. The installer and uninstaller leave your game-data folder in place, including worlds and resource packs. Back up important worlds anyway.

Where do I report a bug?

In the Discord or as a GitHub issue. Please never post access tokens, account files or unredacted logs in public.
