Ultimate Browser

A fully functional Chromium web browser inside Minecraft, with multiple tabs, Picture-in-Picture mode, fullscreen browsing, a chat link interceptor, and admin commands.

Features

Real Chromium browsing — powered by MCEF, so actual websites (Google, YouTube, GitHub, etc.) render and work inside the game, not a fake in-game "web page."
Multiple tabs — open, switch, and close tabs from a tab strip at the top of the browser screen, just like a normal desktop browser.
Fullscreen browser mode — a full in-game screen with an address bar, back/forward/reload buttons, and a "+" button for new tabs.
Picture-in-Picture (PiP) mode — keep a page playing/visible in the corner of your screen while you keep playing Minecraft.
- Draggable and resizable: move the PiP window anywhere on screen and resize it to whatever size fits your setup.
- Fully interactive: click, scroll, and type directly into the page without leaving the game.
- Automatically clamps to your window size, so it never covers more of the screen than it should.
Chat link interceptor — links posted in chat can be clicked to open directly in the browser instead of copy-pasting URLs.
Admin commands — server operators can open a browser or navigate a specific player to a URL remotely.
Persistent state — open tabs and PiP position/size are saved and restored between sessions.
Localized — available in English and Spanish (Spain, Mexico, Argentina).

Keybinds

Notes

Ultimate Browser renders a real, interactive Chromium instance inside the game — treat it like any other web browser: be mindful of what you load and who has access to the admin commands on your server.
