I tried it, and still have it running on a little toy service I built. It's cool, but IMO, it doesn't really seem production-ready for a large-scale service. Last time I updated it, I had to spend a full day sorting out the changes they made to how the server config and user authentication works. Last I checked, they don't even have a suggested script to run it as a service. Going by the contributor graph, it's still essentially a 1-person project.
