The anti-dupe that
actually learns.
Modern servers do not lose to lag. They lose to silent dupes and invisible exploits. DupeWatch ends that: forensic item tracking, smart economy analysis, and a detection brain that gets sharper every single day.
What happens the instant an item moves
Seven stages, zero main-thread cost. Scroll to step through the entire detection lifecycle.
The second it lands in any inventory, DupeWatch is watching it.

Beautiful in-game, brutal on dupers
Real screenshots from the plugin. Click through the tabs. Every screen is point-and-click, right inside Minecraft.
One command. Everything.
Type /dw and run the entire plugin from clean point-and-click menus. No command spam, no memorizing syntax.
Everything, live and in real time
Terminal feed, spread graphs, economy anomaly detection, Discord alerts, and performance at a glance.
Judged against your server averages, not fixed numbers. Shops, voting and honest paydays pass right through.
Rich embeds with case summaries and evidence links. Thresholds are configurable, so your staff channel only hears about what matters.
Six systems working as one
Machine learning, forensic IDs, economy analysis, false positive protection, spread graphs, and a GUI-first workflow.
Adaptive machine learning
Every staff verdict is a training example. Accuracy climbs and false alarms fall, tuned to your server.
Forensic item IDs
Salted, cryptographic serials. DupeWatch tells two identical diamonds apart.
Smart economy analysis
Knows a big honest payday from a balance that is flat-out impossible.
False positive protection
A flag fires only when several warning signs agree at once.
Visual spread graphs
Watch duped items and dirty cash move through your economy, player by player.
99% GUI workflow
Run almost everything from clean point-and-click menus, right inside Minecraft. No command spam, no memorizing syntax.
