Crossfabric
by xNasuni
Crossfabric is a library for Fabric and Quilt that mod developers use to write one codebase across several Minecraft versions.
What it does
Crossfabric library mods use integrate multiversion, a setup that lets a single project target several game versions. The beta builds only support client-side Fabric mods for now, and a later release will add the server side. Either side can run it, and neither needs it to play. Files are published for Fabric and Quilt across 30 release versions, 1.16.5 – 1.21.11, under the MIT License, and the code is open source.
Key features
Multiversion integration
