Maroon vs PraxiLabs

Maroon is a free, open-source immersive physics laboratory for interactive learning, simulations, and experiments. In its virtual environment, users approach a station and teleport to a room containing the related lesson or activity. Simulations emphasize active learning by involving students in the process. Listed physics activities include Coulomb’s Law, Falling Coil, Faraday’s Law, Huygens’ Principle, Point Wave, Pendulum, Van de Graaff, and Optics. The lab also includes titration and sorting experiments, and supports experiment authoring. In the optics activity, users adjust parameters and receive real-time visual feedback while exploring reflection, refraction, lenses, and fiber optics. Maroon runs in a browser and has downloadable Windows PC and virtual-reality versions. Developed with Unity at Graz University of Technology, the project is hosted on GitHub and welcomes contributions, issue reports, and pull requests. Students can contribute functionality, VR experiences, learning experiences, and physics experiments.

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.
