Users should be able to import and export code to a variety of repository services, such as GitLab or Bitbucket in addition to the current GitHub integration.
Implementing this should be a tiered process, with support for importing from other services coming first, commits/pull requests second, and alternative OAuth login/account linking last.

Could possibly use Isomorphic Git to clone repositories:
isomorphic-git · A pure JavaScript implementation of git for node and browsers!
