We have updated the page to recommend Gajim instead. It is a better choice indeed.
Also Conversations doesnt allow for customer server IP address so it's unusable for me. Yaxim does which is why I will have to stay with it. Custom IP server addresses are important if you have DNS/NAT complications within your internal network compared to outside.
Can you use SRV records for this? Or is that unsupported too?
Also, I don't believe that Monal is open source. You might also want to add https://chatsecure.org/.
