Minecraft Schematic Viewer vs SchemViewer

Minecraft Schematic Viewer has no write-up on Specifiction yet; its figures are above.

SchemViewer is a free browser-based 3D viewer for Minecraft .litematic schematic files. It uses the Deepslate WebGL engine for interactive viewing, with controls to rotate, zoom and pan. A Y-axis slicer changes the visible height to inspect schematic layers, while region controls show or hide individual subregions and their bounding boxes. The searchable materials checklist supports filtering and checking off blocks. Technical mode switches between default Minecraft textures and customized technical textures. Users can export block lists and metadata as CSV or JSON; the placement workflow is export-only. The maker says files are processed offline in the browser and are not uploaded to a server. A Canvas 2D renderer provides a fallback to the WebGL viewer. The listed format is .litematic, and listed platforms include web, Linux, macOS and Windows. The project is licensed under MIT. For local use, the README describes cloning the repository and opening index.html in a web browser.
