OvercastUI
An in-game web browser for Minecraft — browse the web, read a wiki, or watch video in picture-in-picture without alt-tabbing or pausing your game.
The web, right there on top of Minecraft. Steam-overlay style, and it never pauses your game.
OvercastUI is a 100% client-side Fabric mod that embeds a full Chromium web browser into Minecraft as a Steam-overlay-style overlay. Summon it with a hotkey (default Shift+Tab) and work with multiple draggable, resizable, tabbed windows on top of your game — read a wiki, look something up, or keep a video playing in Picture-in-Picture, all without alt-tabbing and without ever pausing gameplay.
Features
- Full web browser in-game — back/forward/reload, address bar, and find-in-page.
- Multiple draggable, resizable windows with tab support.
- Picture-in-Picture — keep a video playing in the corner while you play.
- Split-view — read two pages side by side.
- Customizable theme — adjust opacity and backdrop.
- Rebindable hotkey — default Shift+Tab.

- Never pauses your game.
Great for

- Quick lookups, guides, and reference — mid-game, no interruption

FAQ

- Does it pause my game when the browser is open?
- No. Unlike alt-tabbing, OvercastUI never pauses your game — your session keeps running underneath.

- How do I open the browser overlay?
- Press the hotkey, which defaults to Shift+Tab. It's rebindable in the controls settings.
- Is it client-side?

No more alt-tabbing
Every time you tab out to check a wiki or watch a guide, your game pauses or drops focus. OvercastUI keeps the web inside the game — draggable windows, tabs, Picture-in-Picture video, and split view — so you never break your session to look something up.
