Dependencies

What Polymerdeclares it needs, from the author’s own release metadata. A required one has to be installed alongside it or it will not load.

Frequently asked

Does Polymer work on Minecraft 26.3?

Yes. 26.3 is the newest Minecraft version Polymer 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 Polymer support?

Everything the author has declared, from 1.18 up to 26.3. The full list is in the table above, with the Java runtime each version needs next to it.

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

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

Which platform or loader does Polymer support?

Quilt, Fabric. 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 Polymer?

Among the supported Minecraft releases above, the highest recorded requirement is Java 25 or newer. Use the requirement for the exact Minecraft version you run; previews and snapshots may differ.

What does Polymer need to run?

It declares Fabric API as required, so that has to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

What licence is Polymer under?

LGPL-3.0-only, 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 Polymer?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download Polymer safely?

Start with the author's page on Modrinth, 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.
