Frequently asked

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

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

What licence is WorldOptimiser under?

LicenseRef-All-Rights-Reserved, 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 WorldOptimiser?

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 WorldOptimiser 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. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.

Which Minecraft versions does WorldOptimiser work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old mod with no declared version as untested on modern Minecraft.

Details from Modrinth, where the author last updated it on 17 Sept 2025. We do not host files and we do not republish descriptions; every download link points at the author’s own release.

Not indexed yet. Score 43 against a threshold of 55. The page still exists and is still linked; it simply carries noindex until we hold more.
