How to set up your OptiFine for Fabric server
- Create your account, top up your balance and create a Medium server.
- Create the world with Fabric as the loader and Minecraft 26.3 as the version.
- In "Mods", add OptiFine for Fabric's mods from the Modrinth catalog (the list is in the dependencies tab of its Modrinth page). The catalog only shows what works with your world, and the panel installs the right version of each mod along with its libraries.
- Start the server. The first boot takes a bit longer because it downloads and installs the mods.
- Your friends download the
.mrpackmodpack from the panel in one click and import it in the Modrinth App or Prism Launcher. - Share the server address and you're in: they join through Multiplayer.

Frequently asked questions
Which Minecraft version does OptiFine for Fabric need?
OptiFine for Fabric has versions for Fabric: 1.16.5 to 26.3 (32 versions). The newest is "OptiFine for Fabric 4.1-alpha.1" (September 18, 2026). Create your world with Fabric and Minecraft 26.3: that's the combo its latest release is built for.
Can I change the server's Minecraft version later?
Yes, upward: when OptiFine for Fabric ships a newer version, you update and the panel backs up your world first. Going back down isn't possible, because Minecraft can't open worlds saved on a newer version; to play an older one, create another world.
How much RAM does a OptiFine for Fabric server need?
We recommend a Medium server with 8 GB. Its latest version ships at least 71 mods from Modrinth. If lots of people play at once or you explore a ton, size up from the panel without losing your world.
Do my friends have to install OptiFine for Fabric to join?
Yes: every player needs OptiFine for Fabric in their Minecraft, on the same versions as the server. The easiest way is to import the modpack in the Modrinth App or Prism Launcher. If you build the server from the panel's catalog, the .mrpack they download has exactly the same mods.
How much does a OptiFine for Fabric server cost?
With a Medium server and 10 hours of play a week, about $195.33 MXN a month, storage included. With 5 hours, about $122.53 MXN. You only pay while the server is on; if nobody's playing, it shuts itself off.
Can I play OptiFine for Fabric on an offline-mode (non-premium) server?
Yes. Offline mode is a server setting, not a modpack one: you turn it on in the panel's "Access" tab. Use it with the whitelist on and no operators, because in that mode the server doesn't verify who each player is.
