ChemViz3D vs Labster

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.

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.
