The Binder Project is a software project to package and share interactive, reproducible environments. A Binder or "Binder-ready repository" is a code repository that contains both code and content to run, and configuration files for the environment needed to run it.[1]
Since 2017, when the Binder Project was merged into the JupyterHub project,[2] the development communities share many people in common. A common use of Binder is for sharing a Jupyter notebook in a way that the recipient can immediately execute in a browser.[3]
The Binder project maintains core libraries and documentation for running Binder services, which make those projects available, as well as BinderHub, a tool for deploying such services via common cloud computing environments. A public BinderHub portal is hosted by the community at .[4]
A BinderHub lets you launch a publicly executable version of a Binder repository. Given a URL to a repository, it generates a new URL that anyone can visit in a browser to interact with a running version of the code in that repository.
The public BinderHub, mybinder.org, load-balances Binder instances across a federation of contributing institutions, each of which is running its own BinderHub instance.[5]
