Cheaters don't stand a chance.
Stop cheaters before they ruin your server. Nineteen live detection modules backed by a physics prediction engine, a chest GUI that works without any client mods, and a real-time web dashboard - all in one plugin.
Real catches, live server
Purple Anti-Cheat detecting and punishing cheaters in real time - no setup beyond dropping the jar in your plugins folder.
Moderate without leaving Minecraft
Type /purple gui and a full control panel opens in-game. Real items, real inventory slots - every admin can use it with a completely vanilla client.
Players
Paginated heads with live flag counts. Click any to warn, freeze, teleport, kick, temp-ban or permanently ban.
Warning log
Full record of every warning a player has received - the reason, who issued it, and exactly when.
Modules
All 19 detections on one page. Left-click to toggle, right-click to cycle sensitivity, shift-click to change the punishment.
Escalation
Click to tune flags-per-warning and how many warnings trigger a kick, temp-ban or permanent ban. No config file needed.
Ban list
Every banned player with their reason and expiry. Click any to unban instantly.
Active punishments
Temp-bans still running and frozen players. Lift any punishment with one click.
Vanish
Go invisible to all non-admin players to watch a suspect. Items, mobs and other admins can still see you.
Server stats
Total flags, flags by module, players tracked, warnings issued, and live server TPS at a glance.
Protection
Toggle setbacks, lag compensation thresholds, combat-log detection and the setback cooldown in-game.
Discord & API
Link a Discord webhook for live alerts and start the web API for the real-time moderation dashboard.
What it catches
Every module is independently toggleable and tunable. All movement checks pause automatically when the server lags or a player's ping spikes.
Multi-target, impossible angle, perfect-aim streak, snap rotations, autoswing intervals, hits through walls.
Ping-compensated distance to the nearest hitbox point. Laggy players get automatic slack.
Machine-smooth yaw tracking with zero pitch correction during combat. Also catches impossible pitch values.
CPS ceiling, duplicate-interval analysis (catches "randomised" macros), and inhuman click consistency.
Displacement-based anti-knockback. Combo hits discard the sample so victims are never falsely flagged.
Crystal place/break rate and impossibly fast place-then-break timing, checked across 14 samples.
Physics simulation engine - simulates vanilla movement every tick and flags sustained divergence. Lag averages to zero; cheats don't.
Hover detection, horizontal speed cap with potion/sprint scaling, knockback and teleport grace periods.
Dedicated speed check separate from fly, with ground vs air limits, ice exemption, and physics-based ceiling.
Landing from a fast fall with zero fall distance recorded - catches the most common no-fall implementations.
Full movement speed while blocking or sneaking - checks both per-tick speed and sustained patterns.
Walking on the surface of water or lava when no solid block is beneath. Triggers a setback.
More than 30 movement packets per second - vanilla sends 20. Hard to spoof without being obvious.
More than 12 blocks broken in a single second in survival mode.
Block placement rate and robotic jitter-free bridging, with context check for actual bridging posture.
Rising more than 0.6 blocks while on the ground without jumping - catches high-step mods.
Gliding faster than fireworks legitimately allow, sustained over four samples.
Totem re-equipped within 2-3 ticks of it popping - physically impossible for a human to do.
Valuable-ore hit rate combined with beeline tunnelling analysis. Weighted stricter below y=0.
Built for server admins who mean it
Chest GUI
Full in-game inventory menu. Works on every vanilla client - no mods needed.
Discord Alerts
Link your webhook in one command. Embeds fire the moment a player is flagged.
Live Dashboard
Your website shows real-time player flags straight from your server API.
Smart Punishments
Per-module thresholds: auto-warn, kick, temp-ban or ban when the count hits.
Sensitivity Control
Low / Medium / High / Custom per module. Tune for your community's ping.
Flag Decay
Running counts fade over time so old flags don't haunt players forever.
Whitelist
Exempt trusted players, staff, or streamers from all checks with one click.
Violation Logs
Export everything to a timestamped log file for evidence or appeals.
