Concord Consortium Lab vs Labster

Concord Consortium Lab is an open-source HTML5 framework for scientific models, visualizations, graphing, and probeware. Authors define Lab Interactives in JSON, combining models with inquiry controls such as buttons, checkboxes, sliders, and graphs. Interactives can be created, shared, and embedded. Listed model types include Next Generation Molecular Workbench, Energy2D, and Probeware, with bar and line graphs available for activities. Lab combines simulations from multiple modeling engines with data collection from sensors and probes; one demonstrated model explores charged and neutral atoms through two-dimensional molecular dynamics. The framework runs on Android, iOS, and the web, requires SVG support, and lists iOS Safari and Chrome for Android among supported browsers. Concord says current desktop browsers provide the best performance, while simpler models may run on tablets and phones. The project uses Simplified BSD, MIT, or Apache 2.0 licensing. Download archives are available, and local content must be served through a web server. Concord says student and teacher data is confidential and not used for targeted advertising.

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.
