Kotlin for Forge provides bundled Kotlin libraries for mods built with the Kotlin programming language. Available for Forge and NeoForge on Minecraft 1.14 - 26.3, it also supplies loaders for mod declarations and event subscribers, plus utility functions and constants. For players rather than developers, it serves as a dependency mod.
Rent your own Minecraft server and install Kotlin for Forge with one click from the panel when your chosen mods require it.
