Lead developer of Gren here. It's great to see people being interested in the project, thanks for the mention!

Just wanted to add that both websockets and indexed-db is being worked on by members of the community. I'm hopeful we'll have them ready for the 0.2.0 release in December, alongside preliminary nodejs support.

Since the 0.1.0 release, we've added support for local- and session-storage, which was another often-requested feature for Elm.
