Dependencies
What OtterLibdeclares 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 OtterLib work on Minecraft 26.3?
Yes. 26.3 is the newest Minecraft version OtterLib 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 OtterLib support?
Everything the author has declared, from 1.20 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 OtterLib on the client or the server?
Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.
Which platform or loader does OtterLib support?
Fabric, Quilt, Purpur, Spigot, Paper, Folia. 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 OtterLib?
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 OtterLib 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 OtterLib under?
MIT, 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 OtterLib?
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 OtterLib 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.
