Labster vs MolView

Labster provides interactive virtual lab assignments for teaching science concepts and practicing laboratory techniques. Its catalog includes more than 300 simulations across STEM subjects. Learners follow guided scenarios, repeat work at their own pace, and receive immediate feedback. Instructors can use automatic grading, customizable quizzes, and a modular assignment builder. A course mapping tool helps match simulations to a syllabus, and listed LMS integrations include Canvas, Google Classroom, Blackboard, Moodle, Schoology, and D2L Brightspace.

Simulations run in supported browsers on Windows and Mac computers. Some are available on iPads and Chromebooks through the Labster app; smartphones, including iPhones and Android phones, are not supported for playing them. Purchases are available to instructors, faculty, and administrators at educational institutions. A free trial is offered, but there is no free plan. Pricing is on request; institutional or department engagements typically begin at $5,000 a year, billed annually, with final pricing dependent on the solution and implementation requirements.

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.
