GuardianAC

What GuardianAC is

GuardianAC is a free, open-source anti-cheat plugin for self-hosted Minecraft servers running Paper. The maker describes it as a way to protect a server and says its detection covers all Minecraft cheats in config.yml; detection can also be disabled. The pinned version is 1.5.5, with Fast Place Detection listed as an addition. Its stated compatibility is Paper for Minecraft 1.18, so servers outside that combination are not identified as supported. The maker says it is working on bugs, disablers, and bypasses, and offers help with bugs through its Discord support server. Although described as open source, the listing does not specify a license. The maker identifies this as the official GuardianAC listing and warns that other Guardian Anti-Cheat listings are fake. The GuardianAC plan costs nothing and is listed for Paper · Minecraft 1.18.
