Chunkmap vs squaremap

Chunkmap generates top-down 2D maps of Minecraft worlds from region (.mca) files. Its web viewer lets users upload their own region files, and it covers the Overworld, Nether, and End. The Windows CLI can render individual region files or combine rendered images into a single map. Its rendering modes include textures, heightmap, biomes, temperature, downfall, and inhabited views. The CLI is open source under the MIT license on GitHub, and the product is free. Chunkmap supports offline viewing and links to a Discord community. The project is labeled beta and under development, so it may not work as expected. The beta has only been tested with Minecraft 1.21.x worlds; modded worlds and chunks generated before 1.18 are unsupported. The project README also notes that Nether generation is slower than generation for the Overworld and End. The web version is for uploading and viewing region files, while the CLI provides rendering and map-merging options.

squaremap is a free Minecraft server plugin or mod that generates a live world map viewable in a web browser. Its vanilla-like, top-down 2D presentation is designed for navigation and supports live updates, dimension maps, and markers or waypoints. Player markers can show yaw rotation, health, and armor. The project lists Paper, Fabric, NeoForge, and Sponge support; Fabric additionally requires Fabric API. An internal web server is enabled by default and uses port 8080 by default, although a host may restrict available ports. For advanced arrangements such as SSL certificates, the documentation recommends an external web server. Integrations include ChunkyBorder, Heatmap, PlotSquared, Residence, and Towny, plus add-ons for banners, claims, death spots, mobs, signs, skins, vanish, and WorldGuard. Developers can use the API to draw markers, shapes, and icons on rendered maps. Downloads are directed through Modrinth, with development builds on Jenkins. squaremap uses the MIT License, while its Leaflet frontend uses the 2-clause BSD License.
