StackAnvil Bedrock Addon for ViaFabricPlus

Connect to Bedrock Edition servers from a Minecraft Java Edition client with Fabric. This experimental StackAnvil build extends ViaFabricPlus Bedrock with patches that are under upstream review. It is not an official ViaVersion release.

Visit the StackAnvil website for the project overview, build guides, and release information.

Install

1. Use Minecraft Java Edition 26.3 with Fabric Loader.
2. Install ViaFabricPlus and this add-on in the same client. For the tested pairing, get the pinned upstream ViaFabricPlus JAR from the matching StackAnvil release.
3. Keep only one ViaFabricPlus JAR in your mods folder. If your launcher installed another copy, remove the duplicate.

The add-on includes the patched ViaBedrock and CubeConverter libraries. Do not install those library JARs as separate Fabric mods. For a ready-to-import client, use the PrismLauncher bundle from the StackAnvil releases.

Bedrock features

• Connect to Bedrock servers. Sign in with your Microsoft account for online mode servers.
• Open Bedrock Friends and Realms from the ViaFabricPlus screen. View friends, requests, joinable worlds, parties, and Realms.
• Render Bedrock custom entities and player skins.
• Use the classic Dressing Room to select Steve or Alex, or import a skin and cape.

Some Bedrock behavior remains experimental. Test this build before you rely on it for a long session.
