About the CrossSync | Cross-Server Data Syncing

Running a multi-server network requires seamless player data handoffs. CrossSync synchronizes inventories, ender chests, potion effects, experience levels, and hunger across servers in milliseconds.

Uses a dual-layer Redis cache with MySQL persistence to ensure that players switching servers never experience inventory desyncs or rollbacks.

Features a strict server-switch lock that makes inventory duplication during network transfers completely impossible.

Key features

Transfers player inventories and ender chests in under 50ms during server switches.

Anti-Dupe Switch Lock

Freezes player interactions during server handoff until data confirmation is verified.

Full Player State Sync

Syncs health, hunger, potion buffs, active fire ticks, and flight toggles seamlessly.
