Light Anti-Cheat+

Light Anti-Cheat+ is an ArkFlame-maintained fork of LightAntiCheat, a lightweight Minecraft anti-cheat designed to detect common and harmful cheats without adding unnecessary server overhead.

This fork is based on the original open-source project and continues the same core goal: accurate, practical detection for real Minecraft servers, with compatibility across legacy and modern versions.

Project Scope

Light Anti-Cheat+ is not intended to be a heavy, all-in-one anti-cheat suite. It focuses on lightweight detection for the most common and damaging cheats seen on survival, SMP, PvP, and general-purpose Minecraft servers.

Server owners should test and tune the configuration for their player base, server version, combat mechanics, latency profile, and plugin stack.
