Best Fabric Mods for a Free Minecraft Server

Fabric has a smaller but more curated mod ecosystem than Forge. Here are the standout mods to install on your free FreeMCServers.org Fabric server.

Performance (server-side)

These are the highest-impact server-side mods. Install all of them on your Fabric server for free TPS gains:

Lithium — General game logic optimizations. Massive TPS improvement under load.
Starlight — Rewrites the lighting engine. Faster chunk loads, fewer hitches.
FerriteCore — Reduces RAM usage. Useful on memory-constrained servers.
C2ME (Concurrent Chunk Management Engine) — Parallelizes chunk loading. Huge improvement on multi-core servers.
ServerCore — Bundles many small server-side optimizations.

These are for your players' clients, not the server, but they make the experience much smoother:

Sodium — The most impactful FPS mod ever made. 2–4× framerate boost.
Iris — Shader support for Sodium users.
Indium — Adds rendering API support to Sodium for compatibility with other mods.

Create (Fabric port) — Mechanical contraptions, gears, and automation. Wildly popular.
