Frequently asked

Does DupeUtility work on Minecraft 1.21.11?

Yes. 1.21.11 is the newest Minecraft version DupeUtility declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does DupeUtility support?

Everything the author has declared, from 1.21 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install DupeUtility on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

Which platform or loader does DupeUtility support?

Paper. A build for one platform or loader will not necessarily load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for DupeUtility?

Among the supported Minecraft releases above, the highest recorded requirement is Java 21 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What licence is DupeUtility under?

BSD-3, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install DupeUtility?

Choose the release variant for your server platform. Paper, Spigot, Purpur and Bukkit files go in the server's plugins folder; Fabric, Forge, NeoForge and Quilt files go in the mods folder. Restart after installing and check that the Minecraft version matches your server.

Where do I download DupeUtility safely?

MCReference has no release file or checksum recorded for DupeUtility. Check the publisher's Hangar listing for current downloads and verify the publisher before installing.
