BrowsMainer Online
BrowsMainer Online lets players open online browser pages as displays inside a Minecraft world, so a group can watch websites together.
What it does
On Fabric, the browser displays in singleplayer. Display surfaces placed in the world show web pages, with a browser bar that includes a URL field, a ping readout and a buffer status line. Browser data stays on the player's own computer in this local mode.
On a server, the shared displays run through a Paper plugin that the server owner installs. Every viewer sees the same browser content and hears the same audio, and server admins can block websites through a file. For security reasons, some features are disabled on shared server browsers.
The mod targets Minecraft 1.21.11 and is published for Fabric only, with a single file, 0.6.0-alpha for 1.21.11, dated 2026-07-31 on the alpha channel. Chrome, Node and FFmpeg must be installed manually, while the other required runtimes are set up and checked automatically on first start. Paper is the server platform for shared displays, and the project is still alpha software, so some websites and systems work better than others.
