In my attempt to run a completely degoogled phone (GrapheneOS without Play Services) I have noticed that a couple of proprietary messengers have working notifications, for example Whatsapp, Facebook Lite, and Kakaotalk.
I wonder if there is any list of messengers (and related stuff like email clients) showing whether they work on a degoogled phone or rely on Play Services for their notifications?
I am aware of this website for banking app compatibility reports with GrapheneOS, and of Plexus which is a general compatibility database but appears to be abandoned with no updates since 2021.
I’d consider starting such a project on my own but of course this may exist somewhere already?
