Where is safer? Communication in jabber via web form or open source messenger?

Question

Anonymity

Good day.
Please tell me, in your opinion, in what way will communication through jabber be more secure and anonymous? Through a web platform, through a browser with https support, for example, https://jabber.com , or is it more reliable through an open source messenger? For example, the same Psi, Pidgin, Spark, etc. + configure more encryption keys.
Tell me please.
Thank you in advance.

Answer 1

More reliable - through your server, without using other people's services.
Encryption will not be superfluous if you connect to your server through public communication channels, such as the Internet.
It will be through the WEB, or through a native messenger, it doesn’t matter.
