MongooseIM is a scalable and efficient instant messaging server. It implements the open, proven, extensible and constantly evolving XMPP protocol, which is an excellent choice when it comes to instant messaging. To communicate with other XMPP entities, the server uses three main types of interfaces, listed in the table below. XMPP Interface Purpose Connection type Reworked in version C2S (client-to-server) Accept connections from XMPP clients inbound 6.1.0 – 6.4.0 S2S (server-to-server) Federate with other XMPP servers inbound/outbound 6.4.0 Component Accept connections from external components inbound 6.4.0 The C2S interface was reworked and improved already in version 6.1.0 (see the blog post), making it more modern, organised and extensible. In the most recent version 6.4.0, this trend is continued by reworking the S2S and component interfaces while unifying the whole connection handling logic.  [Read More]

It has been a little over a year since Meta announced their proposal for third-parties to achieve messaging interoperability with WhatsApp, with Facebook Messenger following half a year later. Not for everyone, and only because these services were designated as Gate Keepers under the recent Digital Markets Act (DMA) in the EU. So only in the EU, and then with many strings attached. In that time, a lot has been written. Element/Matrix have put in efforts to work with Meta to get some interoperability going.
