What it is

SchemViewer opens Minecraft .litematic files in a browser and renders them as interactive 3D schematics. You can rotate, zoom, pan, slice by Y level, hide regions, check materials, switch texture modes, and export block lists or metadata. Files are processed offline in the browser, with a Canvas fallback and a local clone-and-open option.

Who it suits

Minecraft builders checking .litematic layers and materials Groups that need schematic data in CSV or JSON Users wanting browser-side file processing

Choose SchemViewer when your group needs to inspect a Minecraft .litematic file without paying for a viewer. It gives you an interactive 3D preview, layer slicing, region visibility controls, material checklists, technical textures, and CSV or JSON exports. Browser-side processing keeps the listed workflow offline, and the project can be opened locally from a cloned repository. For those limits, it works best as a focused inspection step before building.
