ReducedX-Anti Cheat review
Free, open-source protection for Paper and Spigot servers running Minecraft 1.21.x.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ReducedX-Anti Cheat is a free, open-source Minecraft Java Edition server plugin from ReducedG. It is designed for self-hosted Paper and Spigot servers running Minecraft 1.21.x, with a focus on combat, movement, world, and packet-related cheat detection. Small and mid-market server operators can use it to monitor KillAura, reach, autoclicking, anti-knockback, hitbox exploits, speed, flight, NoFall, Jesus, Step, Scaffold, X-Ray, FastPlace, PacketFlood, JoinFlood, and ReconnectSpam activity.
Its strongest area is the breadth of detection and enforcement available within a server plugin. ReducedX-Anti Cheat combines staff alerts with low, medium, and high alert levels, violation decay, combination detection, player spectating, and flag-history commands. Replay analysis adds a way to review suspicious activity. The punishment GUI supports warn, kick, mute, temporary mute, temporary ban, permanent ban, and IP-ban actions. Administrators can also configure messages, thresholds, per-world checks, bypass permissions, and staff controls, allowing the plugin’s behavior to be adjusted to different server rules.
Platform fit is the main decision point. The published category specifications identify Paper and Spigot as supported server platforms, while verified Minecraft support is limited to 1.21.x. Deployment is self-hosted, so the product suits operators who want an open-source plugin rather than a hosted anti-cheat service. It is listed as MIT-licensed and downloadable from Modrinth. Choose ReducedX-Anti Cheat for a free Paper or Spigot 1.21.x server needing broad detection and built-in punishment controls. Choose another option if you need support beyond 1.21.x, a hosted deployment model, or AI-based features.
