3D Viewer Online vs Nanome

3D Viewer Online is a browser service for sharing, inspecting and reviewing 3D models. Its 3D Player and APIs can embed models in websites, catalogues and other applications. The viewer provides rotation, panning, zooming, preset views and measurement tools for checking geometry and dimensions. Users can share browser links, while teams add comments, markups and attached datasheets or supporting documents. Access depends on each model’s sharing settings. Listed formats include STEP, IGES, GLTF, 3MF, STL, OBJ, DWG and DXF; DWG and DXF do not support 3D solids. Embedding is available through external links or iframes. The REST API accepts uploads and returns a viewer URL and model ID, with token access and rate limits discussed with the company. The WebGL viewer is described for recent browsers on PCs, tablets and smartphones. The free Regular plan allows ten models and 50 MB files. Premium is $10/month and Business $25/month, both billed monthly.

Nanome is a collaborative platform for visualizing molecular structures and supporting drug discovery work. People can review proteins and small molecules together in real time across web and XR workspaces. Its tools cover measurement, selection, molecule building, protein-ligand interaction analysis, docking pose review, molecular dynamics playback, and rendering. MARA, Nanome’s AI copilot, provides more than 300 scientific tools across 26 categories, including docking, structure prediction, cheminformatics, genomics, and materials science. The platform also offers a REST API for each MARA tool, Jupyter integration, and a Claude Code skill and MCP server. The free web tier accepts PDB, SDF, and CIF uploads; its Starter plan includes three workspaces, one project, 50 MARA credits, five recent files, and seven days of chat history. Paid plans start at $4.17/user/mo billed annually. Every new account gets a 14-day Full license trial without a credit card.
