Why should you use ModSync?
ModSync is a client-server setup that adds transparency to the client's Mods and Texture packs.
Here are more ways ModSync might turn out helpful:
-
Anti-Cheat: Instead of the server running continuous checks for cheats, ModSync presents a 1 time check solution. ModSync doesn't just check your mod directory; It checks all the threads running inside Minecraft.
-
Auto-Authorisation: No need for fancy auth plugins, ModSync generates a unique authorisation key for every device. This will link with the player's username once he joins the server. If someone with a different key tries to log in with the user's account, ModSync will kick them for a mismatched auth key.
-
Modlist & Packlist: All the Mods and Texture packs installed on the client will be listed in the username's log file.
-
Screenshot Player's Gamescreen: Admins can use a command to take a screenshot of screenshots of players gamescreen to ensure texture pack legitimacy. (mainly used to detect Xray packs)
🛡️ Core Security
ModSync doesn't just "ask" the client for a list; it uses a secure challenge-response handshake:
Dynamic Hashing: Every handshake is secured with SHA-512 using a server-side pepper and a unique challenge UUID to prevent packet spoofing.
Privacy-First: Players are prompted to agree to data reporting on their first join, ensuring compliance with privacy standards.
⚙️ Technical Features
Categorized Resource Reporting: Unlike basic list-reporters, ModSync distinguishes between Active (enabled), Inactive (in folder), and Deleted resource packs.
Intelligent Mod Consolidation: Automatically collapses library dependencies (like fabric-api sub-modules) into single entries to keep admin modlists readable.
Historical Audit Logs: Every player gets a dedicated .yml log tracking their mod/pack history across sessions—including timestamps of when a mod was removed.
Remote Diagnostics: Admins can request remote screenshots or even "dump" specific mod/pack files directly from a client to verify suspicious files.
Bedrock Support: Native compatibility with Geyser/Floodgate to skip verification for Bedrock players while maintaining strict security for Java players.
