OneCraft is a simple survival SMP that feels like vanilla but with some cool extra stuff. It runs a few server side mods and datapacks that make the world bigger and more interesting but it still plays like normal Minecraft.
The server has extra biomes new structures and dungeons and things like Distant Horizons and Geophilic so exploring actually feels fun. There are structure and dungeon mods plus Mine Treasure so you can go hunting for loot and adventure instead of just walking through empty terrain.
There is Simple Voice Chat so people can talk in game if they want and the server also connects with Discord chat. Bedrock players can join too so your friends on different platforms can all play together.
It is a small vanilla plus survival world where you can explore build and run dungeons without a bunch of crazy plugins or pay to win stuff. It just feels like a chill place to start a long term survival base and go find treasure with other players.
