Better MC [FABRIC] BMC3 Server Hosting

The short way: start a FadeHost trial and pick Better MC [FABRIC] BMC3; the server pack, the Fabric loader and the right Java install themselves and the server is online in a few minutes. The manual way: download the official server files, install Java 21, run the Fabric installer, accept the EULA, set the memory and open port 25565. Both are described on this page.

Host a server for it: everyone installs Better MC [FABRIC] BMC3 in their launcher and joins one address, and the world keeps running while any of you is on. On FadeHost the pack installs itself when you create the server, the 7-day trial gives 8 GB with no card, and a sleeping server wakes when a friend joins. The manual way is the server files below on a machine that stays on with port 25565 open; LAN and direct connect only work while the host's PC is on and everyone is on the same network.

6 GB for a group of 2 to 4 friends and 8 GB for 5 to 10 players, estimated from the size of the official server pack (572 MB).

From the pack's CurseForge page: every release has a separate "server pack" file with the mod jars and configs (newest: BMC3 [FABRIC] 1.21.1 v45). The client zip is only a manifest. On FadeHost the server pack is fetched and installed for you.

Not on the free tier: it gives 2 GB and Better MC [FABRIC] BMC3 needs 6 GB ($7.50 a month here). The 7-day trial gives 8 GB with no card, enough to run the pack properly.

Minecraft 1.21 runs on Java 21. On FadeHost the right Java is picked automatically; on your own machine install it before running the Fabric installer.

Yes. Everyone joining needs the same Better MC [FABRIC] BMC3 version in their launcher (CurseForge, Modrinth or Prism). The server side is handled by the host; a client on a newer pack version than the server is refused or misses content.

Yes. Upload the world folder through the file manager or SFTP, or use the importer to pull the whole server from another host. Keep the pack version the world was played on until it is safely backed up.

No. Better MC [FABRIC] BMC3 is a Java Edition modpack and Bedrock clients cannot load mods. Geyser lets Bedrock players join vanilla-compatible Java servers, not modded ones.

The usual causes are a client-only mod in the mods folder (shaders, HUD or texture mods), a loader build that does not match the pack version, the wrong Java, or too little memory. On FadeHost the installer removes the known client-only mods, the loader and Java are matched to the pack, and the crash doctor reads the log and names the mod when something else breaks.
