Our verdict on GuardAC
GuardAC is a server-side Minecraft anti-cheat plugin for small and mid-market server operators who want combat-focused monitoring. It connects to a cloud API to analyze combat crosshair movement for KillAura, aim-assist behavior, abnormal combat movement, and sharp changes in player movement style. Support covers Paper, Spigot, Purpur, and Folia servers running Minecraft 1.16 or newer. The plugin is open-source and can run in cloud or self-hosted deployments, with an API platform option also available.
Its strongest feature set is the combination of detection review and staff workflow. Alert-only mode lets moderators review suspected violations before enforcement, while live monitoring, combat feeds, statistics, suspect views, violation tracking, player profiles, and replay analysis add context around incidents. Configurable punishment ladders can trigger alerts, logs, kicks, bans, broadcasts, console commands, and optional combat suppression. Integrations with PlaceholderAPI, WorldGuard, Geyser, LiteBans, AdvancedBan, and the Vanilla ban list help it fit into established moderation setups.
GuardAC is available on a free plan for personal, non-commercial use, with evaluation within the request limit. That makes it a practical starting point for private or community servers seeking AI-assisted combat review without an upfront plan commitment. Its focus is narrower than a general-purpose anti-cheat: the published coverage centers on combat behavior and movement fingerprints rather than a broad set of unrelated cheat categories. Choose GuardAC if aim analysis, staff visibility, player history, and cross-server reputation matter most. Consider an alternative if your priority is offline-only operation or wider detection coverage beyond combat-focused behavior.
