Jami is a decentralised communications application offering voice and video calls, instant messaging, group conversations and file sharing. Unlike conventional messaging services, it doesn’t require a central server to manage communication between users.
The application uses a distributed hash table (DHT) for peer discovery and establishes encrypted connections between participants. Users can create a Jami account without providing personal information, while linking multiple devices to the same identity. It can communicate over a local network even when an internet connection is unavailable.
Jami also functions as a conventional SIP client, allowing users to connect to compatible VoIP infrastructure. This provides an alternative to its native decentralised account system for people who need traditional internet telephony services.
The application is developed by Savoir-faire Linux. It supports Linux, Windows, macOS and mobile platforms.
This is free and open source software.
