After trolling through quite a number of Node.js CMS hopefuls, it seems that Calipso is the most active / well developed CMS so far. Am I missing other options or projects that are more robust and mature at this point in time?
We use Calipso for some of the projects here in my company and it works out fine. If you have love for node you should be fine :) We constantly review other node based cmses, and so far Calipso is most active and favorite.
I highly recommend KeystoneJS, it's still relatively new but i'm already using it in several commercial projects, give it a go! (I also contribute to the project).
