Meshdiff – visually compare two STL versions in the browser, client-side
Meshdiff is a new web-based tool for comparing 3D model files. It supports STL, 3MF, and OBJ formats, allowing users to visually diff two versions of a model directly in the browser. The tool operates entirely client-side, meaning all processing happens locally on the user's machine; it requires JavaScript to run. This approach ensures that sensitive or proprietary 3D files never leave the user's computer, addressing privacy concerns for designers and engineers. The tool is presented as a simple, accessible solution for version control in 3D modeling workflows, enabling quick visual inspection of changes between iterations. No server-side processing or file uploads are involved, making it a lightweight and efficient option for comparing model revisions.
Meshdiff enables client-side 3D model comparison, offering developers a privacy-preserving way to visually diff STL, 3MF, and OBJ files.
