What is ModWatch?

ModWatch is a synchronization system designed to give server owners full visibility into the client-side environment of their players. By pairing a Bukkit/Spigot/Paper plugin with a lightweight Fabric client mod, you can ensure that your server remains a fair playground for everyone.

[!NOTE]

For Players: You only need to install the Client Mod.

For Server Owners: You need to install the Server Plugin on your server.

Why choose ModWatch?

Instant Insight: Admins can see a full list of a player’s mods and active resource packs with a single command.
Automated Blacklist: Instantly punish players using forbidden IDs like xray, wurst, or freecam.
Periodic Challenges: Our unique security layer sends hidden verification “challenges” every 30 seconds to ensure players can’t bypass the check after joining.
Global Search: Want to know who’s using a specific mod? Use /modwatch find <name> to scan everyone online.
Anti-Outdated: Enforce a minimum version of the mod to keep your security standards high.

Advanced Security

ModWatch doesn’t just check once on join. It uses a Challenge-Response protocol:

Join Handshake: 2 seconds after joining, the server requests data.
Periodic Pings: Every 30 seconds, a new random challenge is generated.
Verification: If a client fails to reply or sends an invalid response, they are immediately kicked.
Resilience: Optimized networking handles connection spikes and cross-platform communication seamlessly.
