HeroSync
Latency compensation that makes high-ping gameplay feel local.
Why it exists
Purpose
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.
Who it's for
Players on high-ping servers, everyone who wants a smoother-feeling game, and anyone who wants less perceived lag without server mods.
Key capabilities
Instant action registration
Player actions are registered locally at zero latency, so the game responds immediately.
Smart reconciliation
Outbound and inbound packets are observed and reconciled against server truth.
Clean rollback
A dedicated rollback engine reverses only what needs reversing when server state differs.
Broad version support
Shipped for every version from 1.21 to 1.21.11, plus experimental 26.x builds.
