It would really help if the author had a list of "features" on the github project. It is a bit difficult to figure out what exact functionality the project supports.
Pyrite inherits most of Galene's features, which are listed at https://galene.org. (Galene's server has some extra features that are not used by Galene's native client yet, but were designed for third-party frontends, but I don't think Pyrite is using any of those yet.)
