Run a Terralith server
Nearly 100 new biomes with vanilla blocks — the biggest worldgen upgrade that breaks nothing.
Installs automatically · Live in under 30 seconds · No port forwarding
Terralith rewrites terrain generation with only vanilla blocks — skylands, deep canyons, proper mountain ranges — which means one killer property for servers: players can join with a completely unmodded client. It's the biggest visual upgrade you can give a survival server at zero friction.
Because it works server-side, Terralith is the classic 'vanilla-plus SMP' foundation: your friends click your address in the normal launcher and spawn somewhere that looks like a wallpaper.
From zero to playing in three steps
Create the server
One click pins Fabric with Terralith staged. The world generates with Terralith terrain on first boot.
Pre-generate (optional)
Add Chunky from the Mods tab and pre-generate a few thousand blocks around spawn — new-chunk generation is the only heavy part of Terralith.
Invite anyone
Players join with a plain vanilla client. No mod installs, no launcher setup — just your address.

Read ›Questions, answered.
Do players need Terralith installed to join?+
No — that's the point. Terralith uses only vanilla blocks and runs on the server, so a stock Minecraft client joins normally and sees all the new terrain.
How much RAM does a Terralith server need?+
4 GB, with the caveat that generating new chunks is CPU-hungry. Pre-generate your world with Chunky and it plays as light as vanilla afterwards.
Does Terralith work on an existing world?+
It only affects newly generated chunks, so an existing world gets visible seams at old chunk borders. Start a fresh world for clean terrain — on Campfire you can keep the old world as a second world and switch between them.
