Free plan available — no credit card required

3D review workflows are stuck in the past. Teams share screenshots of 3D models or rely on screen-sharing calls. Synks is a 3D model review tool that lets you upload GLB/GLTF files and review them interactively in the browser. Rotate the model, zoom in on details, bookmark specific viewpoints, pin comments to exact surface positions, and track approvals — all without installing desktop software.

Why Synks is the best 3D model review tool

Most 3D review requires everyone to install specialized software. Synks renders 3D models directly in the browser using WebGL, so anyone with a link can rotate, zoom, and annotate. Product designers, VFX artists, architects, and stakeholders all review from any device.

Pin comments stick to the model surface as you rotate, so feedback always stays in context. Bookmark specific viewpoints to ensure everyone sees the same angle. Compare model versions with side-by-side views and automatic change detection.

Whether you're a product design team reviewing CAD exports, a VFX studio iterating on digital assets, or an architectural firm checking building models — Synks is the 3D model review tool that fits your workflow.
