Monal IM

Free Jabber/XMPP client for iOS and macOS

Monal is a open source XMPP instant messaging client for MacOS and iOS which strives to be the go-to client for these platforms just like the app Conversations is for Android. XMPP in general is an open and standardized protocol for real time communication. Anyone can host their own server and communicate freely with each other, just like with email and just like email the used addresses are of the form "user@domain.tld". In this project, Monal will among others add end-to-end encryption to its chat interface, in this case the OMEMO XEP which uses a so call double ratchet mechanism to provide strong protection of the confidentiality of messages.Within the project, the team will also implement various other XEPs such as audio and Video (A/V calls), adding modern functionality and improving interoperability with other clients.
