Chunkmap vs mcview

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.

mcview is a top-down 2D map viewer for Minecraft Java and Bedrock. It is listed for iOS, macOS, and Windows, with Windows releases and links to the Microsoft Store, plus Mac releases and an Apple App Store link. Release notes state support for Minecraft 1.21.10 and mention a renewed world list along the left side of the window. The project is GPLv3 licensed and described as free; the plan is free. Its README acknowledges JUCE, Google Material Design Icons, colormap-shaders, je2be-core, libminecraft-file, and Android SDK sources, but does not describe third-party service integrations. Release tags are marked as signed with the committer’s verified signature. The project pages reviewed do not state a support policy or contact.
