Enter a Roblox ID or username to check for any duped items associated with that name.
These are our official inventory scanning bots. Only these accounts are authorized to scan inventories on our behalf.
Enter a Roblox ID or username in the search box above. The system will search through our collected data to identify any items associated with that user that appear to be duplicated based on our detection methods.
Items marked as duped are flagged because our system detects multiple active copies of the same item across different owners. Other sites rely on manual reports, while our list is generated automatically by our bots hopping servers and comparing inventories. This means we often identify more dupes than other sources. An item may appear clean at first if only one copy is visible. Later, when another copy surfaces in trading, our system updates and marks it as duped. That’s why some items can change status over time. If you believe your item has been falsely flagged as a dupe, please report it by opening a support ticket here
We've logged over 8 million items and counting! Our comprehensive database continues to grow daily as we scan inventories across the Jailbreak community, providing the most extensive dupe detection available.
Unlike the old dupe calculator, you can't manually report dupes with this new system, making it way more accurate. It's powered by the comprehensive data we have collected, including unknown dupes that don't show up on competitor websites.
The data should be highly accurate for the most part. While this is a beta feature, we're confident in the reliability of the information displayed.
Yes. While the detection is still fully automated based on our collected data, if you believe an item is incorrectly flagged you can report the false dupe by opening a support ticket in our Discord support channel.
Items are constantly being added each day to grow our database bigger. Our system only tracks items that have been scanned by our bots, so if a user hasn't been scanned recently, their items won't appear in results.
The old deprecated dupe calculator will be kept for reference but is no longer maintained. This new dupe finder provides more accurate and comprehensive results.
