Amrita Virtual Lab vs PraxiLabs

Amrita Virtual Lab provides browser-based laboratories and learning materials for distance education and experimentation. Learners can use simulations, interactive animations, and remotely triggered experiments, alongside web resources, video lectures, and animated demonstrations. The project says it has built 1,500 experiments, with procedures, lab manuals, quizzes, and other supporting resources; the platform also offers on-the-spot assessment. Subject areas range across computer science, engineering, biotechnology and biomedical engineering, and physical and chemical sciences. Examples include neurophysiology simulations, physics tools such as a DC circuit simulator and virtual optics, and a wireless sensor network lab. Teachers can monitor student progress and adjust instructional material, and the platform includes experiment authoring and LMS integration. Labs are hosted for open access through the project websites. The team offers free online and offline classes for students and faculty at nodal centres. The Free access plan is listed at free under the Nodal Centre Program, with no registration fee for that program. Participating institutions must choose at least three experiments and have at least 300 students using the labs.

PraxiLabs provides virtual science labs and educational content for learners and education providers. Its simulations cover biology, chemistry, and physics, with more than 220 available in the Semester and Annual plans. Learners interact with experiments in 3D, can repeat them, track progress, and receive immediate feedback. Oxi, described as a virtual science lab partner, provides personalized guidance during simulations. The platform also includes multiple-choice quizzes and assessments, reports, and analytics. Individual subscriptions are limited to one user: the Free Plan gives one month of access to three simulations, while the Monthly Plan provides any 10 simulations. Semester and Annual plans include access to all 220-plus simulations. The School plan lists Moodle, Blackboard, and other LMS integrations, plus a built-in mini-LMS; Teacher and University plans are also offered by quote. PraxiLabs runs online in a modern browser on a computer or laptop, with no installation required. The Free Plan costs nothing, the Monthly Plan $6.99 a month, the Semester Plan $29.99 a month, and the Annual Plan $44.99 a year.
