What is OptiFabric?

OptiFabric is a Fabric modpack for Minecraft 26.3, published by Creanter on Modrinth since 2024.

With 1.8M downloads it ranks #14 of the 518 most-downloaded Modrinth modpacks we track, and its authors tag it as lightweight and optimization.

Our notes on OptiFabric

What sets it apart

Despite the name, the listed contents do not include OptiFine. This is a Fabric modpack that aims to cover what OptiFine does using separate mods.

The performance core is Sodium, Lithium, FerriteCore, ImmediatelyFast, Entity Culling, More Culling and C2ME. Shaders come through Iris.

The larger share of the list is about OptiFine feature parity for resource packs: Continuity for connected textures, Entity Model Features and Entity Texture Features, OptiGUI for custom interfaces, Animatica for animated textures, Skyboxify for custom skies, LambDynamicLights, Zoomify and a capes mod.

That is the main difference from a leaner pack such as Remarkably Optimized, whose latest mod list leaves out entity model, GUI, animation and dynamic light replacements.

Who it suits

Players moving from OptiFine who use resource packs that depend on OptiFine-format features, and who want those to keep working on Fabric. Players who only want higher frame rates can get by with a smaller pack.

Before you install

Fabric only. The version list runs from 1.16.5 to 26.3, with a current build for each Minecraft version. Most builds from 1.16.5 through 26.2 were re-published between September 1 and 6, 2026.

The changelog shows that ports to a new Minecraft version start out incomplete. During the 26.3 betas, a long list of mods was removed temporarily and brought back as each one updated. The 9.0.0 notes list Polytone as removed until it updates, and it is absent from the latest dependency list. The newest version may have fewer features than older ones for now.

Version 9.0.1 swapped the Configured Defaults mod for the author’s own default-settings system.

A few bundled files are not Modrinth-hosted projects, including Skyboxify and the default configuration mod.

The project page promises higher frame rates and lower memory use but publishes no benchmark figures to back that up.

Playing with friends

Modrinth marks the pack as client-only with no server component. The mods change rendering and resource pack handling, so a matching server is not needed, and no server pack is provided.

The pack also includes a mod aimed at faster server list pinging, according to the project page.

Server-side behavior for specific networks, such as anti-cheat compatibility, is not documented.
