PackWiz-ard
Server owners who run a PackWiz modpack can keep it current with PackWiz-ard, a server-side Library mod that updates the pack from its source.
What it does
PackWiz-ard reads a PackWiz or Packweave modpack source and runs an update command that brings the listed mods up to their latest versions. Its automatic updates can run on a configurable interval in minutes. Dependencies declared by the pack are fetched and loaded as well, so required mods arrive together.
The mod runs on Fabric and NeoForge for 1.21.1 and supports both loaders for modpacks. It is server-side only, so players join without installing it. Its update process can use two updater backends, and a sync command sets the selected one. The mod requires Fabric API on Fabric, Forge Config API Port on NeoForge, and Matthiesen Core on both loaders. Released under the MIT License, it is open source, and its source code, issue tracker and wiki are public.
Key features

An update command pulls the pack's mods to their latest versions, and an interval setting repeats the check automatically.

Mods declared as dependencies by the pack are fetched and loaded so that required libraries are present.
Two updater backends
The mod supports the default PackWiz ecosystem and the Packweave alternative backend, and a sync command selects which one applies.
Client update screen
A button on the title screen opens a dedicated screen that shows the pack link, its validation result and whether a client update is available.
Manual or automatic refresh
The screen refreshes lightly on open, and it can be switched to a manual-only refresh mode.
