Forge or Fabric: pick first

  • Forge — biggest mod catalog (Create, Twilight Forest, most CurseForge packs). Heavier, slower startups.
  • Fabric — lighter, faster ticks, better for performance mods (Lithium, Sodium). Smaller mod catalog but growing fast.

If you're running a known modpack, use whatever loader the pack ships with. Otherwise default to Fabric for performance, Forge for variety.

Step 1 — Provision a free modded server

On [FreeMCHost](https://new.freemchost.com), create a server and choose Forge or Fabric as the type. The loader is preinstalled — no manual installer to run.

Step 2 — Pick your RAM correctly

Modded Minecraft eats RAM. Rough minimums:

  • Light Fabric pack (10–20 mods) — 2 GB
  • Mid Forge pack (50 mods) — 4 GB
  • Heavy modpack (All The Mods, Create-based) — 6–8 GB

The free tier shares up to 24 GB across users, so a 4 GB modpack runs comfortably as long as it's not also peaking at 30 chunk view distance.

Step 3 — Upload mods

Two ways:

1. File manager — drag .jar files into mods/, restart. 2. CurseForge modpack — upload the server pack zip, extract into the server root, restart.

Make sure every player has the exact same mod list (same versions). Clients with missing or extra mods will be kicked.

Step 4 — Tune for modded performance

In server.properties:

  • view-distance=6 (modded chunks are expensive)
  • simulation-distance=4
  • max-tick-time=-1 — stops the server from shutting itself down during a heavy chunk gen tick

For Forge, add to forge-server.toml (or config/forge-server.toml):

  • removeErroringBlockEntities = true
  • fullBoundingBoxLadders = false

Troubleshooting

  • "Mod rejections" on join — version mismatch between client and server. Share a download link to your exact mods folder.
  • Server crashes at startup — check the console for the missing dependency line. Most crashes are a missing API mod (Fabric API, Architectury).
  • Insanely long world load — first start of a big pack can take 5+ minutes. Don't restart during it.

Want a no-mod alternative?

If your group just wants more performance + plugins without the mod hassle, go [Paper](/paper-minecraft-server). Plugins like ViaVersion, EssentialsX, and CoreProtect cover 90% of common modded features.
