MapViewer

MapViewer is a lightweight mod for Minecraft 1.20.1 based on Forge that allows you to open your server's Dynmap maps or any web maps directly inside the game using a built-in browser based on MCEF.

No more switching between windows — access the current world map with a simple hotkey press.

🚀 Key Features

• Launch Dynmap maps or custom web maps directly in the game (settings in the config/mapviewer-server.toml file)
• Works on the built-in Chromium browser (MCEF)
• Fully interactive interface — click, zoom, and navigate like in a regular browser
• Customizable hotkey (default: O)
• Lightweight and client-friendly

⚙️ Configuration

Edit the file:

/config/mapviewer-server.toml

And specify the address of your Dynmap or web map:

dynmapUrl = "http://yourserverip:8123"
