Meshdiff: Browser-Based 3D Model Diff Tool
Original: Meshdiff – visually compare two STL versions in the browser, client-side
Why This Matters
Client-side 3D diff tooling addresses a gap in version control workflows for hardware and product design teams.
Meshdiff is a free, client-side web tool that lets users visually compare two versions of 3D model files—including STL, 3MF, and OBJ formats—directly in the browser without uploading data to a server.
Meshdiff is a browser-based 3D model comparison tool available at meshdiff.com. It allows users to load two versions of a 3D file—supporting STL, 3MF, and OBJ formats—and view the differences visually side by side or overlaid. All processing is performed client-side using JavaScript, meaning no model data is transmitted to external servers, which preserves privacy for sensitive or proprietary designs. The tool requires JavaScript to run and is accessible directly via a web browser with no installation needed. It is positioned as a diff tool for 3D models, analogous to code diff tools used in software development, enabling designers and engineers to track changes between iterations of a model.
