mcmap vs Worldlens

mcmap creates isometric pixel-art maps from Minecraft save files. It reads saves from the standard folders on Linux, macOS and Windows, and produces a PNG image by default; an option divides maps into square image tiles. Rendering settings include circular or coordinate-bounded areas, dimension selection, shading, lighting, water and beacon toggles, and map direction. A JSON color file lets users customize block colors and rendering types. The renderer uses all computer threads and processes terrain in batches. Rendering a whole map at once may require 10+ GB of RAM, and a fragment-size option can manage batch size. Use is through a terminal or PowerShell, with an experimental GUI available for Windows. The v3.0.0 release specifies Minecraft 1.13+ support. The project is distributed under GPL-3.0, with precompiled binaries and source code available for free. Building it uses CMake and depends on zlib, PNG, fmt and spdlog. The project notes that merged batches can produce visible lines in oceans; changing fragment size or water rendering settings may help.

Worldlens is a TypeScript port of BlueMap for rendering Minecraft worlds into 3D maps and browsing them. The project describes a Windows desktop app, two container images, and a separate Wharf desktop app for deploying a container locally or over SSH. The desktop app can render local worlds offline using BlueMap’s Java renderer, which requires Java, or connect to remote BlueMap servers through a token-gated proxy. A standalone CLI renders and serves the map web app, with a watch mode for map updates. Rendering can also run on another machine over SSH, in Docker, or through GitHub Actions. Documented integrations include Docker, SSH, GitHub Actions, GitHub Pages, remote BlueMap servers, and Home Assistant boolean entities for scheduled settings. The stated target world versions range from Minecraft 1.12.2 through 26.x. The repository is MIT licensed. Its public 1.0 compatibility contract is Windows-only, and Windows releases are unsigned and may prompt a SmartScreen unknown-publisher warning. An add-on system, static export, and multi-server dashboard are listed as future work.
