Frequently asked

Does CurveBuilding work on Minecraft 1.21?

Yes. 1.21 is the newest Minecraft version CurveBuilding 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 CurveBuilding support?

Everything the author has declared, from 1.14 up to 1.21. The full list is in the table above, with the Java runtime each version needs next to it.

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

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

Which platform or loader does CurveBuilding support?

Spigot. 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 CurveBuilding?

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.

How do I install CurveBuilding?

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 CurveBuilding safely?

Start with the author's page on SpigotMC, which is where the data here is synced from. MCReference does not host or repackage files. When available, recorded download links go to the source for that release; verify the publisher, filename and any available checksum before running it.

Works on the same versions

Ordered by how much of the recent Minecraft version coverage overlaps, not by popularity.

Details from SpigotMC, where the author last updated it on 20 Aug 2025. We do not host files or republish descriptions. Available download links point to the author’s own release.
