CoyIM
What is CoyIM?
CoyIM is a standalone chat client that focuses on safety and security. It is a self-contained program that runs on Windows, Linux and macOS. CoyIM only supports one chat protocol - XMPP (sometimes known as Jabber). CoyIM has carefully picked and chosen the features that are necessary to create a good chat experience, while keeping the attack surface of the system to a minimum.
It also has built-in support for Tor, OTR and TLS. The Tor support allows users to become anonymous while chatting, OTR makes end-to-end encryption of communication possible, and TLS adds another layer of encryption for the communication with chat servers. These features are not plugins or extras in any way.
CoyIM is implemented in Go. Many other implementation languages open up the door for a large number of attacks; we try to minimize those risks by using Go.
