Yeah, sorry, I got confused. Beeper mini does need servers to keep the notification service alive. And thus not crazy to ask for 2$ a month. Beeper cloud could indeed do without servers I guess, but I don’t know anything about that. I was just keeping up with the development of pypush (the python poc) and reverse engineering progress.

I don’t understand your point of “you have to log in with a google account”. I understood that was a requirement to check subscription status (and as such limit fraudulent apk’s).

But that seems to be a different story than “opensourcing this would mean a competitor could do it for free”.

You can already do this for free with pypush. And if you want to use something else then python you could build something based on it with any language as pypush is completely open source.
