Build a seed here, or upload a .archipelago you generated
elsewhere.
Players connect via a bare ws://host:PORT — not a URL path.

The player bundle (apworld + client DLL + docs) and the bare apworld for hosts, plus the GitHub and Nexus pages. Take both halves from the same release.
Host a New Room
How room hosting works:
The web page at
Each room owns its port for as long as the room exists, so an address you have already handed out keeps working across restarts — and can never end up pointing at somebody else's seed. It only answers while the room is running.
/room/<id> shows status and logs.
The game connection is a separate bare WebSocket port —
ws://host:PORT — which your AP client connects to directly.
These are different addresses and must not be confused.
Each room owns its port for as long as the room exists, so an address you have already handed out keeps working across restarts — and can never end up pointing at somebody else's seed. It only answers while the room is running.
ws://, not wss://: room ports are published straight through and do not
speak TLS. Browser-based clients, which require wss://, cannot connect to them.
