Intave is a high performance anticheat plugin for Minecraft (Paper, Spigot, Purpur & Bukkit), developed since 2016 and battle tested on some the worlds largest Minecraft servers. After nearly a decade in producton and shutting down in mid 2025, we made Intave source available so any server can use it for free.
Features
- Movement simulation: Unlike traditional module based anticheats, Intave accurately simulates player movement plus client side entity and block data to detect even the smallest manipulations
- Combat & interaction checks: Prevent attack reach beyond 3.0 blocks and other combat heuristics
- Heuristic detection: Counters killaura, auto clicker, placement cheats like scaffold, fast break, backtrack, tickbase, timer and much more
- Performance: We build Intave with performance in mind and run simulations in parallel on async threads to impact server TPS as little as possible
How Intave works
Instead of checking individual actions in isolation like module-based anticheats, Intave simulates what a legitimate Minecraft client would do. Intave simulates movement, entities and block interactions and flags anything that deviates from vanilla Minecraft behaivor. Heuristic checks layer on top to catch killaura, auto clickers and other cheats that don't break simulation logic at all.
