Frequently Asked Questions (from users)
This is the simplified version! For technical answers, see the "expert mode" supplement.
General
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 or unofficial - see the expert FAQ for more details.
Are there any premade Fabric modpacks?
Published Fabric modpacks can be found on websites such as CurseForge, Modrinth, Technic, FTB and ATLauncher. A few modpacks are also distributed as exports in the CurseForge format, Modrinth format, MultiMC format, or another format.
How can I install a premade Fabric modpack?
You can use launchers to browse for or install modpacks. The CurseForge App, MultiMC, Prism Launcher, GDLauncher, ATLauncher, Technic Launcher, and FTP App will allow you to do so. Some modpacks also allow you to download a “server” pack and install it in Minecraft Launcher.
What launchers can I use to play with Fabric mods (on a custom/home-assembled modpack)?
As of November 2021, the following launchers are available for this:
- Official Launcher - an installer is available on Fabric's download page.
- CurseForge App - supports Fabric, just choose “Fabric” then select a version when creating a modpack.
- GDLauncher - supports Fabric, just choose “Fabric” then select a version when creating an instance.
- ATLauncher - supports Fabric download and installation.
- HMCL - supports Fabric download and installation, including sources from mirror websites.
Please keep in mind that Fabric API is a separate component and must be downloaded separately - you can find it here.
We recommend MultiMC due to its superior user experience for modded environments.
What launchers can I use to share a Fabric modpack?
As of 30th June 2019, the following launchers are available for this:
Interoperability
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?
No. Forge mods must run on Forge, and Fabric mods must run on Fabric. You cannot mix mods.
- 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 interoperability a high-priority goal, as our focus in our limited time dedicated to the project is on supporting the Fabric community and its developers and users.
Can Fabric run together with OptiFine?
Consider using an OptiFine alternative, as unofficial mods such as OptiFabric may not be compatible with your mods.
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. Sponge does not yet have a ready API or a working implementation for 1.14, the Minecraft version that Fabric runs on.
