Moonrise Compats
by Sixik
Moonrise Compats adds targeted fixes so mods that conflict with Moonrise can run alongside it, with patches for each supported pairing.
What it does
Moonrise Compats applies small integration patches where a mod changes Moonrise's internals through mixins or overwrites. Each patch targets one specific pairing, fixing the conflict or adding a bridge where another mod expects vanilla behavior, so both mods can coexist more reliably. Patches exist only for mods that need them, and each one depends on the supported mod it targets.
The mod follows Moonrise's base version with an added patch suffix, so a build such as 0.1.0-beta.15+2eae1b1.1 is the first compatibility patch for Moonrise build +2eae1b1, and .2 is the second. A patch revision therefore matches one exact Moonrise build. Moonrise must be installed properly for the layer to work. The mod is published for Fabric and NeoForge, for 1.21.1 only, under the GNU General Public License v3.0 only, and its source code and issue tracker are public.
The server needs Moonrise Compats, while clients may leave it out. Anyone who reports a breakage should include the Moonrise build and the Compats build in the report.
Key features
Targeted conflict fixes
Patches correct incompatibilities caused by mixins and overwrites that changed Moonrise's internal code.
Vanilla bridge integrations
Small bridges let mods that expect vanilla behavior work when Moonrise has altered it.
Per-build patch revisions
Each patch carries a suffix on the Moonrise build it fixes, so revisions can be matched to an exact Moonrise version.
Dependency-based patching
A patch applies only when its supported mod is present, so unrelated setups are not modified.

Latest build for each game version and loader.

How it compares
Chlorophyll is a server-side only Fabric mod for 1.21.4 – 1.21.7 under a custom license and is not open source, so it targets a different version range and loader. Create Repair is open source under the MIT License and runs on client and server for Fabric, Forge and NeoForge, but only for 1.20.1. Moonrise Compats is open source under the GNU General Public License v3.0 only, with the server required and the client optional, and is limited to 1.21.1.

What the author says
Moonrise Compats is a compatibility layer for Moonrise that provides targeted fixes/patches for mods that don’t work properly when Moonrise is installed. Moonrise can replace/rewire large parts of vanilla internals for performance. While that’s great for optimization, it can break assumptions made by other mods …
