Mine View Tool vs Tectonicus

Mine View Tool is a free web viewer for navigating Minecraft worlds in 2D and 3D. Users can upload a .mcworld file, a .zip Java world, or files from a Bedrock world’s db folder, then inspect the surface, caves, or underwater landscape. Resource selection can highlight locations such as Diamond Ore or Ancient Debris. Navigation supports rotation, panning, zooming, arrow-key movement, and clicking the map to jump to a location. If the uploaded files contain them, the viewer can display the Nether and the End. Uploads are limited to 200 MB. The home page says uploaded files are stored for no more than 24 hours; the privacy policy describes storage on a server reached through a unique random ID, periodic deletion, and no transfer to third parties. The provider says it uses commercially acceptable protection measures but cannot guarantee absolute security. Google Analytics data, including IP addresses, is transmitted to Google in the United States. Mine View Tool is based in Bucharest, Romania. Terms prohibit automated-script use and state that users must be over 18.

Tectonicus generates a detailed, zoomable map from a Minecraft Java world by building a 3D model and rendering map images. Its stated aim is to make maps resemble what players see in Minecraft. It runs on Linux, macOS, and Windows; maps can be viewed offline or served from a web server. Setup involves downloading a release, preparing an XML configuration file, and running the program from the command line with Java. Later runs using the same options are quicker after the initial render because only changed tiles are rendered. Players can filter which signs appear, and signs marked with #view can create first-person views with configurable height, angle, field of view, and nighttime rendering. Release 2.31 supports Minecraft 1.21 through 1.21.11, but not Minecraft 26.1. It also adds rectangular world subsets and arm64 LWJGL libraries for M-series Macs and possibly other ARM systems. Generated images can consume gigabytes of disk space depending on world size; WebP or JPG output and closestZoomSize can reduce storage use. Copper golem statues do not work, and shelves render only partially.
