Frequently Asked Questions (from users)

This is the simplified version! For technical answers, see the expert FAQ.

Interoperability

What Minecraft versions does Fabric support?

For most cases, the answer is “snapshot 18w43b and above, releases 1.14 and above”.

There exist ways to run Fabric with older versions - modded or vanilla, but they're currently non-trivial - see the expert FAQ for more details.

Can Fabric run together with Bukkit/Spigot/Paper?

Not at the moment. This may change by the end of the year, but is unlikely to be officially supported.

Can Fabric run together with Forge?

  • Fabric does not currently work on top of Forge on modern Minecraft versions.
  • It is theoretically possible to create a way to do so - that is to say, there are no known major technical obstacles in accomplishing such.
  • There were some experiments and discussions done in this regard (as of 30th June), but nothing usable by end users or mod developers.

The development team does not consider Forge interop a high-priority goal, as our focus is on supporting the Fabric community and its developers and users.

Can Fabric run together with OptiFine?

Not officially. However, unofficial mods exist to faciliate the launching of OptiFine for 1.14+ on Fabric. Your mileage may vary, however.

Oh no! I've tried enabling shaders on OptiFine and my world looks all weird!

Fabric's rendering patches, while as minimally invasive as possible, make some assumptions about the data format used internally by the vanilla rendering system. Shaders break this assumption, so things go awry. Workarounds do exist and are implemented by the most recent versions of said unofficial mods.

DO NOT downgrade Fabric API as a workaround for this. It's a bad idea.

Can Fabric run together with Sponge?

Not at the moment.
