What it does

MossyLib is a library mod from LopyMine that provides basic utilities for other projects from the same author. Its code is written once for several loaders, so the same source supports Fabric, Forge and NeoForge. Fabric API is required, and Mod Menu and YetAnotherConfigLib (YACL) are optional.

The mod is client-side only, so servers do not need it and players are the only ones who install it. Files are published for game versions 1.20.1 – 26.3 across 15 release versions, with Fabric, Forge and NeoForge builds. The latest files are 1.6.0+26.3+fabric for 26.3 and 1.6.0+1.20.1+forge for 1.20.1, both dated 2026-09-21. Thirteen other mods require it, among them Inventory Particles, Collision Fix, Inventory Interactions, Bathymetry and Emotecraft: Borrow Their Emote (EBTE). The mod is released under the Creative Commons Attribution No Derivatives 4.0 license and is not open source, though its source code, issue tracker and wiki are public.

Key features

  1. Shared utilities

    A set of helper code that other projects by the same author draw on instead of carrying their own copies.

  2. YACL theme

    A configuration screen theme built on YetAnotherConfigLib that gives related mods a common look.

  3. Snapshot builds

    Builds are published for snapshot versions such as 26.1, 26.2 and 26.3, alongside the release line.

Players of dependent mods

Who it’s for: Players who run a dependent mod that lists this library as a requirement, and developers who want the shared utilities and YACL theme in their own projects.

How it compares

Full comparison

CRM is a Fabric-only mod that is client-side only and open source under the GNU General Public License v3.0 only, for 1.20.1 – 26.1.2. Pufferfish API covers Fabric, Forge and NeoForge with a client and server environment and an MIT License for 1.20.6 – 26.3, so it reaches more loaders but also needs installing on the server. MossyLib differs by being client-side only and not open source, with a license that bars derivatives.

Questions

Does MossyLib need Fabric API?

Yes. Fabric API is a required dependency, so it must be installed next to MossyLib on Fabric.

Does a server need MossyLib?

No. The mod is client-side only, so a server runs without it, but a player who joins with a dependent mod needs it on the client.

Is the YACL theme required?

No. YetAnotherConfigLib (YACL) is an optional dependency. The theme applies to its configuration screens when that mod is also installed.
