MeshDiff

Meshdiff Meshdiff is a browser-native “Figma for 3D diffs” — giving hardware engineers, makers, and 3D-printing teams a visual way to see exactly what changed between 3D model versions. - Visual 3D Diff Engine: Compare STL, 3MF, and OBJ files and instantly visualize geometry changes voxel-by-voxel. 🟢 Green shows added material; 🔴 red shows removed material. Adjustable tolerance and volume-delta metrics make revisions easy to understand. - Built for Makers & Communities: Inspect remixes, tweaks, and CAD revisions from platforms like Printables and Thingiverse before committing time, filament, or a print run. See what actually changed instead of comparing filenames and screenshots. - Printability Checks: Run real-time wall-thickness and overhang analysis to identify potential print failures before the model reaches the print bed. - Free Community Diff Tool: The free Meshdiff diff tool runs 100% locally in your browser using WebAssembly. Your files never leave your device, providing a private way to compare models without uploading proprietary designs. - Pro Cloud Workspaces: For teams that need persistent project history, Pro adds secure cloud workspaces, version tracking, 3D-pinned review comments, and team sign-off workflows — turning model comparison into a collaborative 3D review process. Meshdiff turns “What changed?” from a manual inspection task into a visual, measurable, and collaborative workflow.
