Byulnuri is a Minecraft multiplayer platform made by Byulgurm, designed to help friends connect and play together with less setup. It currently supports Minecraft Bedrock Edition, including mobile, console, and Windows Bedrock. Hosts install Byulnuri, start a LAN world in Minecraft, and create a room that the service connects automatically. They can then share a single link through messaging apps or other channels. Friends do not need the Byulnuri app: tapping an invitation link launches Minecraft and connects them to the game. Players can also browse live rooms on the web and join available cloud servers or friends’ rooms.

For hosts, Byulnuri provides a floating in-game dashboard for managing servers in real time, including kicking or banning players, broadcasting messages, and monitoring activity. The platform also offers chat channels that remain accessible outside the game and preserve messages. Byulnuri describes its connection technology as using custom relay and compression to support low-latency play on mobile. The basic multiplayer connection and host controls are free.
