Minecraft compatibility checker
Check a profile's game version, loader and Java version against the FireClient in-game client requirements.
How it works
This checker compares the profile settings you select with the current FireClient in-game client target: Minecraft Java Edition 1.21.1, Fabric and Java 21. The launcher can support other game versions and loaders; this result only describes whether the FireClient HUD and in-game menu are supported for the selected profile. It does not scan installed mods or change your settings.
Questions
What is the FireClient in-game client target?
The FireClient HUD and in-game menu are built for Minecraft Java 1.21.1 on Fabric with Java 21.
Can the launcher run other Minecraft versions?
The launcher supports other profiles too. The FireClient in-game mod is only included for the supported Fabric 1.21.1 target; see the versions page for details.
Does this checker upload my profile details?
No. The check runs in your browser. Nothing you select is uploaded.
