NXAntiCheat review
A focused combat detector with configurable violations and escalating enforcement.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
NXAntiCheat is an open-source, server-side anti-cheat plugin for Minecraft servers running Paper 1.21 or newer. It is designed for small, mid-market, and enterprise server operators who want combat-focused behavioral analysis without installing a client-side component or inspecting binaries. The plugin examines server-received behavior, with checks for attack-interval patterns through click entropy and aim behavior through rotation quantization. Its scope suits operators prioritizing targeted combat monitoring over broad coverage across multiple cheat categories or server platforms.
Its strongest operational feature is the combination of detection, calibration, and enforcement controls. Administrators can configure violation thresholds and use alert-only calibration before applying penalties. Violation levels decay over time, while escalating kicks and temporary or permanent bans provide graduated responses. Per-player offense history is stored by UUID, and commands cover checks, player information, and offense-history resets. This gives server teams a structured way to review repeated behavior and adjust punishment thresholds around their moderation policy.
NXAntiCheat is a focused choice rather than a general-purpose anti-cheat suite. Its detection coverage centers on click entropy and rotation quantization, and its supported environment is limited to self-hosted Paper servers on Minecraft 1.21 or newer. Operators who need those combat checks, configurable escalation, and an open-source deployment model should find the scope aligned with their needs. Servers requiring wider detection coverage, different server platforms, or versions earlier than Paper 1.21 should choose a product built for those requirements instead.
