A documentation engine written in Python. Sphinx supports many features that are necessary for scientific and scholarly publishing. It is one of the core technologies that Jupyter Book uses.


A free, public service for running reproducible interactive computing environments. Binder is a 100% open source infrastructure that is run by members of the Jupyter community. The underlying technology behind the Binder project is BinderHub.


The underlying technology of mybinder.org, BinderHub is an open source tool that runs on Kubernetes and utilizes a JupyterHub in order to provide live, reproducible interactive computing environments that users host on GitHub.

Google Colab#

A Jupyter Notebook service from Google that provides access to free computing resources, including GPUs and TPUs.


A core open source tool from the Jupyter community, JupyterHub allows you to deploy an application that provides remote data science environments to multiple users. It can be deployed in the cloud, or on your own hardware.


An open source tool for executing and caching the outputs of Jupyter Notebook content. Outputs are cached in a hidden folder so that they do not need to be included directly with your source files.
