Hi Simonster, Thats a great question & a valid concern considering the acquisitions of tools like Mendeley [1]. We are equally focused on tools for collaboration & reproducibility, but our efforts the past few months have been focused on building an MVP.

With Banyan, your data will always be open & you're free to take it with you anywhere. If you want to move your repos to github/bitbucket/another service, you're easily able to do so
