Pack Gate
by RZ
Pack Gate checks a modpack's update source and blocks game access when a newer remote version is listed than the one installed.
What it does
On startup the mod reads a remote version file that the modpack author hosts at a direct URL. If that remote version is higher than the version provided in the config, Pack Gate blocks access and presents a screen to the player instead of loading the game. The check is simple and covers a single task.
The mod suits modpacks that must be updated before play, since the update prompt cannot be skipped by continuing into the world. Because the file must be reachable by direct URL, file sharing platforms such as MediaFire and MEGA do not work as hosts. Google Drive and Dropbox links can work if the URL is modified to point to the raw file, and sites like PasteBin or GitHub can serve the version file as raw text or JSON.
Pack Gate is a Forge mod for 1.20.1 only, released under the MIT License. It is open source and runs on the client alone, so servers do not need it. Its first and latest file is 1.0.0, published on 2025-08-25.
Key features
Remote version check
The mod compares the version in a hosted file with the version set in its config and reacts when the remote one is higher.
Access block with screen
When an update is required, the game is stopped and a screen tells the player that the modpack must be updated.
Direct URL requirement
The remote file must be reachable through a direct URL that ends with the file extension, such as a raw text or JSON file.

Use cases
Modpack update gating
A modpack author hosts a version file and sets the local version in the config, so players on an outdated pack cannot load the world.
Who it’s for: Modpack authors who want players to install a new release before they can play, and players who need to see why their modpack will not start.

What the author says
A simple mod that just does one thing: Checks for modpack updates. This is NOT a server mod, it is client-sided only! It WILL crash servers.
