Igilq

I tried it and works good

I do not recommend using FluffyChat on mobile. It is laggy and takes lots of time to load compared to element

Would it need internet access then?

Yes, it wouldn’t get posted here if it wasn’t able to be selfhosted, it is also listed on website that it can be selfhosted using docker

Looks interesting, would it be possible to selfhost it so it could work on client and server at the same time? Even when offline?

It could be because they don’t have any contract signed for delivering in other eu countries
