AutoBuild vs SchemViewer

AutoBuild is a Minecraft building mod for browsing schematics, saving builds, and loading public designs in-game. Its community library is intended for builds shared by AutoBuild creators, although the library page currently shows no listing results. Users can upload.schem files with screenshots, a category, and visibility settings; staff may review submissions before they reach the public library. Public schematics can also appear in Discord updates. The mod supports.schem and.litematic files, offers a 3D preview, and uses an in-game placement workflow. To send a schematic to the mod, users install it and link their website account from the in-game Account tab. AutoBuild is available for desktop and listed platforms include Linux, macOS, web, and Windows. Its plan costs nothing and includes public library access, uploads, and in-game loading. AutoBuild+ costs nothing, but is available only through official giveaways; active access adds profile customization, premium schematics, premium tools, and future features. Downloads are linked through Modrinth and CurseForge. AutoBuild says it is not an official Minecraft product and is not approved by or associated with Mojang or Microsoft.

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.
