ChemTube3D vs MolView

ChemTube3D is a free chemistry learning resource with interactive three-dimensional structures, animations, and supporting information. It covers organic mechanisms, organic structure and bonding, inorganic chemistry, polymers, and A-level chemistry for students, lecturers, and practising chemists. In a web browser, the JSmol viewer lets users manipulate animated structures. Organic reaction schemes show bond breaking and forming, charges, and lone pairs. Learning designs guide activities built around these visual models. Pages can be embedded in a learning management system or virtual learning environment through LTI; the site reports testing with Canvas and Blackboard, with the LTI tool supplied through OpenOChem. Free iOS and Android apps are available, with the iOS app offering selected Organic Chemistry and Structure and Bonding material. Selected transition-state models can be downloaded in STL and X3D formats for 3D printing. ChemTube3D also provides virtual labs, molecular modeling, and reaction simulation.

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.
