CheckHacks vs FoxAddition Anti-Cheat

CheckHacks is a free, server-side Minecraft anticheat that detects client-side mods and hack clients using the Sign Translation Vulnerability. Players do not need to install a client mod: the plugin briefly places signs with special translation keys and checks the client’s response. Administrators can choose METEOR, TRANSLATE, or KEYBIND detection modes for each mod and add custom detections in checkhacks.yml. DoubleCheck repeats scans that return DETECTED or PROTECTED to help reduce false positives. CheckHacks can check players after Grim, Vulcan, Spartan, or Matrix flags them, and supports custom commands and detection alerts. A browser editor running on the game server lets administrators review scan history, look up players, and start checks. Access uses one-time tokens, while scan records are kept in a built-in SQLite database. Named server platforms include Bukkit, Folia, Paper, Purpur, and Spigot, with Minecraft versions 1.21 and later listed. The maker warns that client patches can temporarily block the detection method. The project is MIT-licensed, and donations are optional.

FoxAddition Anti-Cheat is a free, self-hosted Minecraft server plugin that adds checks alongside another anti-cheat. It supports Spigot, Paper, and Folia, with automatic detection for Folia and traditional Paper or Spigot servers. The Modrinth listing covers Java Edition versions from 1.7.x through 1.21.x and 26.1.x. Listed detections include irregular packets, break aura, bed aura, chest aura, nuker, and invalid movement. Administrators can edit configuration values and disable checks in selected worlds. Available responses include cancelling packets or actions, notifying, kicking, ejecting, and applying a setback or pullback. With GeyserMC it can detect Bedrock players, while Floodgate can control checks by edition. DiscordSRV can send configurable alerts to a chosen channel; optional logs record violations in dated text files. Installation requires placing FoxAddition.jar in the plugins folder and PacketEvents 2.11.0 or newer. The latest listed release is 1.2.3 Beta 2, under an ARR license.
