Overview #
HeroSync is a client-side latency-compensation framework. It does not reduce your ping — it reduces what your ping feels like.
Network latency makes otherwise-fine gameplay feel heavy. HeroSync removes that feeling client-side: your actions register instantly, then reconcile with the authoritative server — rolling back cleanly when the server disagrees.
Quick start #
- Download the HeroSync JAR for your Minecraft version.
- Place it in your Fabric mods folder (Fabric API recommended).
- Join any server; actions now feel responsive immediately.
- Configure or disable features from the in-game settings if provided.
Frequently asked questions #
Does this work on servers without the mod?
Yes. HeroSync is client-side and requires nothing on the server.
Will it get me banned?
It compensates for latency like predictive clients do. Always check server rules.
