What is Osscar?
OSSCAR is an open-science online platform for education and research that hosts software, simulation, and data-analysis tools. It is designed as a collaborative environment that helps people build and use interactive computational tools for teaching and research. The platform emphasizes open science, computational thinking, and easy access to classroom-ready applications.
A core feature is that OSSCAR tools are delivered as web applications generated from Jupyter notebooks. That makes it possible to wrap interactive interfaces around existing open-source simulation codes and expose them through the browser. The site also highlights widgets and extensions that support building these applications, along with open-source code that users can explore and contribute to.
The website presents prebuilt course applications, including tools for quantum mechanics and computational materials science. It also provides guidance for developing new interactive web applications with OSSCAR technologies. This makes the platform useful both as a set of ready-made teaching tools and as a framework for creating new ones.
OSSCAR is aimed at instructors, researchers, and students who need lightweight, deployable computational tools for learning or research workflows. The project’s stated goal is to support a wide range of computational classes and research areas, while keeping deployment and interaction straightforward. The site also points users to project documentation, code, and citation information for those who reuse the notebooks or technology.

Frequently asked questions about Osscar
What is OSSCAR?
OSSCAR stands for Open Software Services for Classrooms and Research. It is an open-science online hub and collaborative platform for hosting software, simulation, and data-analysis tools aimed at education and research.
How are OSSCAR tools delivered?
The site says OSSCAR tools are provided as web applications generated from Jupyter notebooks. This lets the platform present interactive tools in the browser, often by wrapping existing open-source simulation codes in a user-friendly interface.
Who is OSSCAR for?
OSSCAR is intended for instructors, researchers, and students who need interactive computational tools for teaching, learning, and research workflows. The site frames it as support for computational classes and a broad range of research areas.
What kinds of content does OSSCAR provide?
The homepage highlights course applications, OSSCAR tools for building web apps with Jupyter notebooks, and OSSCAR code. It also points to original educational content and examples such as applications for quantum mechanics and computational materials science.
Can I build my own apps with OSSCAR?
Yes. The website describes OSSCAR as a technology stack for developing interactive web applications with Jupyter notebooks, along with widgets and extensions that support those applications. It is positioned as a framework for easy development and deployment.
Is OSSCAR open source?
Yes. The homepage explicitly refers to open-source code developed by OSSCAR and invites users to learn how to contribute to the project. The project description also emphasizes open science and collaborative development.
Does OSSCAR work only for one field?
No. The project page says OSSCAR aims to support a diverse range of computational classes and research areas. The current examples on the site include quantum mechanics and computational materials science, but the platform is meant to be broader than those examples.
Do I need to install software to use OSSCAR tools?
The website presents OSSCAR tools as web applications, which means users can access them through the browser. That design is meant to make the tools easier to use and deploy compared with standalone desktop software.
What does OSSCAR say about citations?
The site asks users to cite OSSCAR if they use its notebooks or technology. It provides citation guidance on the homepage for both the notebooks/project and the widgets/extensions.
When did OSSCAR start?
The project page says OSSCAR started in 2019. It also notes that it was funded by the EPFL Open Science Fund until 2022.
