No option for fabric servers.

[Zerahu]

There is currently no option to use the badlion api on fabric servers. This should really be added considering fabric with lithium is one of the best performing server alternatives that also makes redstone work consistently with no un-intended behaviours. (unlike bukkit/spigot and paper)

Hey, well it has never been suggested before. I'll make an internal ticket to add support for that 😃

[leobitch]

is ther a fabric mod for that now ?

There's Badlion Client Disabler for 1.14-1.17 Fabric.
It was very much a one time effort, since I don't have any need for it anymore.

May bring myself to update it, but glad seeing there's an official implementation on the way now.
