Schemalook vs SchemViewer

Schemalook is a free web-based Minecraft schematic viewer and toolkit. Its viewer opens.litematic,.schem,.schematic, and.nbt files in 3D, with orbiting, zooming, shadow and day/night controls, and layer-by-layer inspection. It counts required blocks and links each block to a wiki page containing recipes and stats. Files remain on the device unless saved to a Schemalook library. Saved builds can be private, shared by link, or limited to specific people, with download controls. The pixel-art tool converts PNG, JPG, and WebP images into block schematics, accepting files up to 10 MB and 4096 pixels per side. A map-art tool supports layouts up to 4×4 maps. Palette generation suggests block combinations by texture colour and permits palettes of three to eight blocks. The converter exports litematic, schem, nbt, and Bedrock mcstructure formats and warns about replacements for older game versions. The free viewer upload limit is 7 MB, and the workflow is export-only.

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.
