Signal - is a smartphone app created by the Signal Messenger LLC. Voice and video calls are included in the app, as well as instant messaging. E2EE is the default mode of communication unless you want to send an SMS instead. Centralized. When using a centralized messenger, everyone is on the same server or network of servers that is under the management of the same company.
Jami - Video chatting and encrypted instant messaging. Even when TURN servers are utilized, all communications are E2EE and secured with TLS 1.3. Data is only ever saved locally on the devices of the users. Without the use of third-party servers, peer-to-peer instant messengers connect directly to each other.
Element - the Matrix network's default client. The Matrix open standard is an open-source standard for safe, decentralized real-time communication. Federated. Federated messengers make use of numerous, separate servers that can communicate with each other (email is one example of a federated service). System administrators can run their own servers while still being a member of the broader communications network thanks to federation.
