Easy Mod Sync
by frikinjay
Easy Mod Sync is a Fabric and Quilt management mod that makes a server push specified files and directories to connecting players before they enter the world.
What it does
When a player joins, the server sends the files registered for syncing, such as configs, mods, resource packs and other assets the server expects, so the client matches the server before play begins. Transfers can travel over the vanilla custom payload channel in pieces, or over an external method where each file payload is sealed with AES-GCM under a session ID that is used once per connection. The server allows only files explicitly added to the sync registry and blocks directory traversal.
The mod works on either side, and neither side needs it on its own. Files are published for Fabric and Quilt on 26.2 and 26.3, with 1.26.6.1 for 26.3 as the latest file on both loaders. Installation needs Cloth Config API on every loader, and Fabric API on Fabric and Quilt. Snapshot builds are published. The code is under All rights reserved and is not open source, though a public issue tracker exists.
Key features
Automatic file sync on join
Registered files and directories are checked and transferred to each player when they connect to the server.
Transfer methods
Files can move over the vanilla custom payload channel in chunks, or over an encrypted external transfer method.
Connection prompt
Connecting players see a prompt that describes the risks and lets them accept the transfer or disconnect.
Live transfer log
A scrollable event log and progress screen shows file transfers as they happen, and an Exit button lets a player abort safely.
Dynamic command completion
Command arguments tab-complete both local and server files, and folder contents update after typing a name and pressing space or backspace.
