InGameWeb

An in-game Chromium web browser overlay for Minecraft 1.21.11 (Fabric).

Open a full browser inside Minecraft with Shift + Tab — browse documentation, wikis, YouTube, and any normal website without leaving the game. Supports multiple tabs, persistent sessions, and download confirmation.

Known Limitations

• MCEF downloads Chromium binaries (~200 MB) on first launch. This is handled by MCEF, not InGameWeb.
• Audio and video support depends on MCEF's included Chromium build and your OS. YouTube generally works on supported platforms.
• Background media can continue after closing the overlay, but performance depends on the website, video resolution, and system hardware.
• Browser initialization may fail if required system libraries are missing (see MCEF's documentation for platform requirements).
• If MCEF is not installed, InGameWeb will refuse to load (dependency check at startup).
