Schematicraft vs SchemViewer

Schematicraft is a schematic library and converter for sharing Minecraft builds across formats, with support for Hytale Prefab files as well. Its browser converter handles Litematica, WorldEdit/Sponge, legacy MCEdit, Structure Block/Create, Building Gadgets, Bedrock Structure, and Hytale Prefab, and lists 42 conversions. Before downloading, users can see which data will carry over or be dropped; formats that record a Minecraft version allow a version choice. Cross-edition and cross-game conversions translate block names, and some other data may not transfer. The public library has searchable builds, filters, and curated collections. Schematic pages show block counts, unique block types, dimensions, and material lists. Without an account, the converter accepts files up to 8 MB. Schematicraft says it does not keep uploaded files but records encountered formats, blocks, and versions to improve conversions. An official alpha mod adds in-game library access and integration with Create and Building Gadgets 2. Developers can use an API for search, library access, uploads, downloads, and conversion; API endpoints are rate limited.

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.
