In their own words
MolView
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.
