Frequently Asked Questions

Does CapeJS need to be installed on the Minecraft server?

No. Modrinth marks CapeJS as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does CapeJS require?

Use a file for fabric, forge, neoforge and your exact Minecraft version. Supported versions include 1.21.1, 1.21, 1.20.1. Files for different loaders are not interchangeable.

CapeJS is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
