How do I AFK in singleplayer?

MinecraftAFK is built for connecting bot accounts to Minecraft servers - its features (auto-reconnect, anti-AFK, chat, proxies) only apply once an account joins a server.

For singleplayer, you'd typically open your world to LAN and connect to it, but that still requires the host machine to stay running. There isn't a workflow inside MinecraftAFK that handles a true singleplayer save without that.

If you're trying to AFK on a multiplayer server, start with the Quickstart and Connect to a server guides instead.

Why servers, not singleplayer

Every MinecraftAFK feature - auto-reconnect, anti-AFK, chat and spam commands, join messages, proxies - exists to keep an account logged into a server. A singleplayer world has no login session for a bot to hold, no chat to route, and no connection to reconnect, so there's nothing for the client to manage.

The closest workaround

If you only need a world to keep ticking, open it to LAN from the host machine and connect a second account to that LAN address - but the host computer still has to stay on, which defeats the usual reason for going AFK. For genuine hands-off, computer-off uptime, run a small server (or a host like Realms) and connect to it with the web client.
