Always Multiplayer
by PaulNZ
Always Multiplayer opens a singleplayer world to other players online as soon as it loads, so friends can join without anyone turning on the multiplayer setting first.
What it does
When a singleplayer world loads, the mod publishes it for online play on its own. Friends can then connect without the host having to open the world to LAN first, which is the usual manual step. The mod is built for Fabric and NeoForge, targets 26.2 and 26.3, and is published as snapshot builds as well as releases. It is client and server, so the host and every player who joins need the mod.
Access can be limited to friends only. A host can use the native server commands for whitelist and ban management, and set a default game mode that applies to other players who connect. Whitelist access restrictions are there to prevent unexpected connections. Fabric API is required on Fabric, and Mod Menu is an optional addition. The code is closed: the mod is released under All rights reserved and is not open source.

Use cases
Playing with friends after a world starts
A host who loads a world in singleplayer can let friends join right away, without changing settings during the session.
Keeping a world private
Restricting access to friends and enabling the whitelist keeps unexpected players out of an open singleplayer world.
Who it’s for: Players who want to host a singleplayer world for friends, and small groups who prefer to manage joiners with server-style whitelist and ban commands.
