Jami: Instant messaging and video calling
Official website jami.net
Our take
Fully peer-to-peer with no central server is an unusually pure privacy design, and that is the real draw. It also explains the friction: without relays, reliable delivery depends on both peers being reachable, so calls and messages can be finicky in practice. Worth it for people who want genuine decentralization and will tolerate the connectivity tradeoff; frustrating if you expect always-on delivery.
