Gajim

Gajim is a free and open-source instant messaging client for the XMPP (Jabber) network. It is cross-platform, available for Linux, Windows, and macOS, and is designed to provide a native-feeling desktop experience with a focus on simplicity and reliability. The project is written primarily in Python and uses the GTK toolkit for its user interface, with a modular architecture that supports multiple XMPP accounts and user profiles.

Key features include support for multiple accounts, presence information, contact rosters, and file transfers. Gajim provides access to standard XMPP features such as multi-user chats (group chats), message history, avatars, and message formatting. The client emphasizes ease of use, with straightforward conversation management and configurable notifications. Its plugin system allows optional enhancements and integrations, including end-to-end encryption through available plugins.

Security and privacy: Gajim supports end-to-end encryption via plugins that implement XMPP-based encryption schemes, enabling users to use encryption for private conversations if desired. The project focuses on adherence to XMPP standards and interoperability with other XMPP services and clients.

Licensing and development: Gajim is released under the GNU General Public License and is maintained by a community of volunteers. Development follows open-source practices, with releases and updates coordinated through the project’s website and distribution channels.
