ViaSlidy adds a version-selection slider to the Fabric client, letting a player switch Minecraft protocol versions in game.

FabricClient-side onlyGNU General Public License v3.0 onlyOpen source1.21.4

What it does

The slider sits in the top-right corner and replaces the default ViaFabricPlus interface with a simpler selector. Only the client needs it, so players join multiplayer servers without installing anything. Builds target 1.21.4 only, with 1.0-beta as the latest Fabric file, released 2026-07-09 on the beta channel. The mod is open source under the GNU General Public License v3.0 only.

Key features

  1. Simplified interface

    The slider replaces the default ViaFabricPlus screen with a cleaner version selection control in the top-right corner.

  2. Version change on release

    The version only changes when the mouse button is released, so dragging the slider does not cause stutter.

  3. Multiplayer screen access

    The slider is available on the multiplayer screen, where a player can pick a version before joining a server.
