OneUseMod

Players who host or join a Blue Goblin Egg hunt use OneUseMod to coordinate in a party. A host opens the settings once and picks Host or Guest, then a single click invites players. Boopers are invited automatically up to 20 and can still warp. Party members request coordinates with the bleggcoords command, the blegg command, the bc command and about 40 other aliases, and the party leader is the only one who answers. Extra slots such as bc2 can be added, and an empty slot sends nothing.

Warp analytics track where a player has been. The mod warns when a non-ironman player lands in the lobby after a warp that was likely brought about by them, checks the Crystal Hollows lobby, and reports which players from the mod visited a given lobby within the last 6 hours. It also tells the player when a server has already been visited. Alerts appear on screen and in chat, and a player can be pinged when another player finds a blegg to share their own finds.

The mod is client-side only, so only the player's own client needs it and servers run without it. It requires Fabric and is published under the Apache License 2.0 for 1.21.5 – 26.2 across 11 release versions, with 1.1.4+26.2 for 26.2 as the latest file. The code is not open source.
