CheckMOD review
A focused, open-source plugin for screening client brands, loaders, mods, and channels.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CheckMOD is an open-source, self-hosted Minecraft server plugin for administrators who want to screen client-side signals at player join. It targets Bukkit and Paper servers in the 1.20.x and 1.21.x ranges, with coverage for client brands, Forge classic handshakes, FML3 blacklisted mods, Fabric loaders, and network channels. Its fit is strongest for small and mid-market server teams that want configurable client-mod and loader checks rather than a broad behavioral anti-cheat system.
The plugin’s main strength is focused detection depth. Administrators can define client brand, mod-ID, and network-channel allowlists or blacklists, enable vanilla-only access, and track client channels. Detection runs as a join-time single pass, with warn and kick actions available for enforcement. Commands cover configuration reloads, player mod and channel inspection, detected-player listings, and statistics, giving operators several ways to review the signals CheckMOD collects. PacketEvents is required, so deployment includes that dependency alongside the plugin.
CheckMOD is a practical choice when the policy is specifically about identifying client brands, mod loaders, Forge/FML3 handshakes, or suspicious channels. It is less suitable for teams looking for a wider anti-cheat suite centered on behavioral analysis or broader gameplay monitoring. The product also has a narrow language footprint, with Simplified Chinese currently supported. Choose CheckMOD for targeted, configurable join screening on self-hosted servers; choose an alternative when behavioral detection, wider ecosystem coverage, or broader operational scope matters more.
