MolView
What it is
MolView is a web application for sketching and viewing small molecules, with API access and molecular modeling features. Its sketching canvas supports structural formulas, reaction arrows, electron-pushing arrows, configurable styles, and keyboard shortcuts. A 3D viewer synchronizes with the canvas as molecules change. Chemical searches accept common names, IUPAC names, SMILES, InChI, InChIKey, and molecular formulas. Depending on the plan, users can save and load sketcher or viewer content, create shareable links, and export structural data or SVG files. The embeddable sketcher web component works in vanilla JavaScript and React, with customizable toolbar and diagram styling. The free plan requires no sign-up for 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. MolView is operated by Bergwerf Labs in the Netherlands.
For and against
For
- 3D viewer follows sketching changes automatically
- Search supports multiple chemical identifiers
- Reaction and electron-pushing arrows supported
- Shareable links and export options available
- Embeddable JavaScript and React component
Against
- Free plan cannot save diagrams
- API sketcher access requires subscription or license
- New app omits protein and spectroscopy viewing
- Help center is under construction
The verdict
MolView combines small-molecule sketching, synchronized 3D viewing, chemical search, and export tools. Plan limits matter if you need saving, advanced exports, API access, or older protein-related views.
Who it suits
MolView suits students, teachers, authors, developers, and others working with small-molecule diagrams. Developers can embed its sketcher in JavaScript or React projects.
