Craftmatic review
A free, open-source browser toolkit for creating and exporting Minecraft schematics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Craftmatic is a browser-based Minecraft schematic toolkit from tribixbite for builders who need to generate structures, inspect builds in 3D, render views, and export files for further use. It is free and open source, with a web application that supports structure generation, drag-and-drop schematic uploads, gallery browsing, interactive viewing, and exports. The project also includes a JavaScript library and command-line interface for parsing, writing, generating, rendering, and converting schematic data.
Its strongest area is the breadth of its creation and presentation workflow. Users can generate structures using multiple structure types and style presets, then examine them through an interactive Three.js viewer. Craftmatic can render 2D floor plans, cutaway isometrics, and exterior views, while scene conversion supports movement between Three.js scenes and .schem files. Standalone HTML viewer exports are useful when a build needs to be shared as a self-contained visual presentation rather than only as a schematic file.
Format support extends beyond the core Sponge Schematic v2 (.schem) workflow, with exports and category-listed support covering .litematic, .glb, .mcaddon, .mcpack, .stl, .obj, glTF, Three.js JSON, and HTML. That makes Craftmatic a practical choice for users moving schematic data into different viewing, modeling, or content workflows. It is less suitable for anyone who needs to import complete Minecraft worlds or place builds directly in an existing world, because its placement workflow is export-only. Choose Craftmatic for open-source browser-based creation, visualization, and conversion; choose another tool when world import or in-world placement is central.
