    Signal is so privacy friendly that requires your phone number to register. A phone number which in many countries has to be registered with providing your ID. Private messenger my arse!

    Wire is free, open source and easy to use and, most importantly, PRIVATE. It transmits data only in an encrypted way that even the creators of Wire cannot see, so you can be sure your content is YOURS, and not something the likes of Microsoft (who own Skype) can read, analyze, hand on to authorities or lose to hackers.

    no server's involved to store our data and no id needed to chat, a complete alternative to something like whatsapp

    only problem is the push notification makes the app non functional, so local DHT is the only option

    This is an excellent Skype replacement. It's free, open source, encrypted and you don't need to install anything. You simply go to the website, choose a link and email it to the person you want to speak with. Everything happens in your browser. You can password protect your session, have group conversations, share screen, chat and collaborate on text documents. Easier even than Skype and much more private.
