1) There's Binder, which is the infrastructure for building computational environments around repos, and BinderHub, which hosts the executable code online. Binder's model, as I understand it, is to develop the infrastructure and then have universities/institutions/whatever host BinderHub: https://binderhub.readthedocs.io/en/latest/ 2) One of my favorite contributions from the team is repo2docker, which turns requirements.txt or equivalent into Dockerfiles: https://repo2docker.readthedocs.io/en/latest/, integration into binder described here https://blog.jupyter.org/binder-2-0-a-tech-guide-2017-fd4051... 3) Not just Jupyter notebooks, also R/Rstudio/Rshiny: https://github.com/binder-examples/r

Some demos and examples: https://jupyter.org/try all the repos linked from there are backed by mybinder.org (The interpreted C++ one blows my mind) Some examples if you want to know how to configure things: * Install Python dependencies via requirements.txt https://github.com/binder-examples/requirements * Jupyter with R and RStudio: https://github.com/binder-examples/r * Julia support: https://github.com/binder-examples/demo-julia * Installing additional APT packages: https://github.com/binder-examples/apt_install (I work on Binder)
