Our notes on Cobblemon Official Modpack [Fabric]

What sets it apart

This is the pack published by the Cobblemon team itself. Its purpose is narrow: wrap the Cobblemon mod in performance, visual and convenience mods without changing the rest of Minecraft much.

The mod list on the project page reflects that. Performance comes from Sodium, Lithium, FerriteCore, Krypton and Entity Culling. Convenience comes from Xaero’s Minimap and World Map, plus JEI and EMI for recipes. The page lists no extra Pokemon datapacks, gyms or quest lines.

Because the same team maintains it, the pack tracks the mod closely. The changelog shows pack releases numbered after the Cobblemon version they ship, with 1.8.4 published in late October 2026.

Who it suits

It suits players who want Cobblemon as its developers present it, and anyone who wants a clean base before adding their own mods. Packs such as COBBLEVERSE build regions, gyms and extra mechanics on top of Cobblemon. This one does not.

Before you install

The pack lists Minecraft 1.20.1 and 1.21.1, but the recent releases in the changelog are all for 1.21.1.

The authors state a minimum of 2.5 GB of memory and recommend 3 GB or more.

A shader pack (Complementary Reimagined) and a leaves resource pack are bundled but switched off by default, according to the project page. Iris is included to run shaders.

A separate NeoForge edition exists for players who prefer that loader. Its page shows it needs extra compatibility layers for a few mods that the Fabric edition runs natively.

The project page also mentions a single-player tutorial world called Cobbled Farms.

Playing with friends

Cobblemon must be installed on both the client and the server. Both the mod and the pack are marked that way on Modrinth.

The project page says there is no official Cobblemon server. It points players to the public server list on the Cobblemon website and to paid hosting.

The page also says a client running this pack can join a server that has only Cobblemon and Fabric API installed. That means friends do not all need the full pack, as long as the Cobblemon versions match.

The page refers to a server package, but the recent Modrinth releases each contain a single pack file and no separate server download. How to obtain a server build is not documented on the page.
