Live Web Maps

Web maps render your world into tiles or 3D models and serve them through a small web server. Players use them to find each other and to see builds, and server owners use them to show off a world to people who have not joined.

Dynmap is the long-standing option: a Google-Maps-style 2D view with optional surface, cave and flat renderings, and markers for homes and regions. It runs on several platforms and has its own integrated web server.

BlueMap renders a 3D model of the world that you can rotate and zoom in the browser. It is generated by the server and is known for its detailed look; its documentation covers deployment behind your own web server.

Both use CPU and disk to render and update maps, and a large world takes a long time on the first render. Plan for that, set a render area, and consider running the renderer outside peak hours.

Think about privacy before you publish. A live map can show where players are and where their bases are. Hide or delay player positions on a survival server where location matters, or restrict the map to your players.

Does a live map slow the server? Rendering uses CPU and disk, mostly when chunks change. Limit the area and schedule heavy renders for quiet hours.

Can I hide where players are? Both maps let you control whether and how player markers show. Check each one's configuration documentation.
