About Via Fabric Plus

Via Fabric Plus is a Minecraft mod for the Fabric client that builds on the ViaVersion plugin. It lets players connect to multiplayer servers from almost every Minecraft version, including Classic, Alpha, Beta, and Release, and it fixes issues the original project did not address. According to the source, these fixes aim to make older servers feel closer to how they originally played, with improvements to movement, block and entity interactions, and graphics.

The mod has clear limits. It works only with the newest Minecraft client version, runs only on Fabric, and affects multiplayer only, not singleplayer worlds. It is clientside only and does not support resource packs from older versions. Players who want to use older clients are directed to the original ViaFabric. Bedrock Edition servers and Realms are supported through a separate addon based on ViaBedrock.
