This is something I forgot to mention… thank you for the question.

Keet is amazing for that because, being 100% peer to peer, it does not need any servers to send information and so there is not any cap on the files size! You can send huge files to everyone directly from your computer to their computer, always E2EE! Logically it depends on your and their connection speed / reliability… and it is important that both are online so it works better. Moreover there is not any algorithmic compression so, for example, pictures are sent as they are, while on 99% of the communication apps they are compressed before sending with loss of quality.

On SimpleX, I do not remember if there is a size cap at the moment but they are working on a way to send big files easily without people been online simultaneously and without compromising too much on P2P.

Let’s say that Keet is 100% P2P without compromises and for this reason it can be a bit more clunky sometimes, while SimpleX is using some compromises on the P2P model.

I personally use both. SimpleX more for chatting especially with people I do not know and Keet more for calls, desktop sharing and file sending with people I know.
