Collaborative Calculation and Data Science

CoCalc is a virtual online workspace for calculations, research, collaboration and authoring documents. This includes working with the full scientific Python stack, SageMath, Julia, R Statistics, Octave, and many more. It also offers capabilities to author documents in LaTeX, R/knitr or Markdown, storing and organizing files, a web-based Linux Terminal, communication tools like a chatrooms, course management and more. It is the best choice for teaching remote scientific courses.


Install CoCalc on your server or computer

You can easily use CoCalc on your own computer for free by running a Docker image.


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.
