CoCalc is web-based software that enables collaboration in research, teaching, and scientific publishing. It includes Jupyter Notebooks, Sage Worksheets, a LaTeX Editor and a Linux Terminal to help people work together in real time from different locations. It also has a Computational Whiteboard for expressing and sharing ideas and running code. It is available for free and can be upgraded for internet access, better hosting quality, and other features. It can also be used for teaching courses with flexible course license options. It is also possible to run CoCalc on your own infrastructure.
CoCalc supports sophisticated calculations that arise in teaching, research, and authoring documents. This includes working with the full data science and scientific Python stack, SageMath, Julia, R Statistics, Octave, and much more. It also offers capabilities to author documents in LaTeX, R/knitr and Markdown, storing and organizing files, a web-based Linux Terminal, an X11 graphical desktop, and communication tools like a chatrooms, course management and more. It is the best choice for teaching remote scientific courses.

You can obtain a packaged version of CoCalc for your own on-premises infrastructure: CoCalc Cloud. It runs on Kubernetes and inherits the security and scalability of the SaaS platform.
CoCalc was formerly called SageMathCloud. It started to offer way more than just SageMath and hence outgrew itself. The name was coined in fall 2016 and changed around spring 2017.
