The Explorer's Friend renders a live topographic map of a Minecraft world and serves it from an embedded web server. It runs on a server using Fabric, Quilt, NeoForge, Spigot or Paper, with different builds depending on the platform and Minecraft version. Explored chunks appear as players move through the world; full renders read region files on worker threads without loading chunks. Players can open the map in a browser using vanilla Minecraft clients, without installing a client mod. Separate layers show claims, player positions, markers and Waystones. Claim data can connect to several protection systems or be imported from JSON. Server administrators can disable or round player positions; invisible players and spectators are hidden by default. The server binds to 127.0.0.1 by default and has no built-in account system, so the project recommends a reverse proxy for public maps. Its optional outbound connection downloads the official vanilla client JAR once and verifies it by SHA-1. The MIT-licensed project is free, with live updates, dimension maps and read-only HTTP endpoints.
