Jami

Jami is a Peer to Peer messaging app backed by the Free Software Foundation, also known for other small projects like the GNU, GIMP, Emacs, GCC, etc. What this means is that the app does not need any kind of servers, be it centralized or decentralized ones in order to function.

Pros

Cons

Conclusion

I see a big potential in Jami. Every feature you can think of is present, and the experience is smooth for the most part. If something happens to the world wide web, Jami will still be able to message anyone whom it can reach through the network. This is an advantage that will most likely become very relevant in the near future.
