ChemViz3D vs MolView

ChemViz3D is a free browser-based 3D molecular animation tool for chemistry teaching. Students can rotate, pause, and zoom around atoms and bonds in real-time scenes, while a keyframe editor creates custom reaction animations. Animations can be shared by link and viewed without installing software. ChemViz3D converts.chemx or.json animation files into Blender-ready Python scripts. Its molecule toolkit, built with RDKit.js, supports structure analysis, visualization, and SVG or MOL downloads. An image-to-SMILES workflow accepts uploads, pasted screenshots, and image URLs, with.smi and.mol export. The product describes using PubChem PUG-REST and NCI/CADD services for molecular data and structure resolution. It is used in UTS chemistry courses. Individual students, learners, and educators receive the free plan at free with no sign-up required. The full interactive player requires WebGL and a modern desktop browser is recommended.

MolView is a web application for sketching and viewing small molecules, with API access and molecular modeling support. Its canvas handles structural formulas, reaction arrows, electron-pushing arrows, configurable styles, and keyboard shortcuts. A 3D viewer updates automatically as you edit a molecule. Chemical searches accept common names, IUPAC names, SMILES, InChI, InChIKey, and molecular formulas. Depending on the plan, you can save and load sketcher or viewer content, create shareable links, export structural data or SVG files, use transparent backgrounds, and set image resolution. Developers can embed the sketcher web component in vanilla JavaScript or React and customize its toolbar and diagram style. The free plan needs no sign-up and supports searching, sketching, and viewing, but cannot save diagrams. Paid plans include Student at $9.00 per year, Publisher at $250.00 per year, Academic at $4919.00 per year, and Standard at $9919.00 per year.
