Gajim is a free, open-source, and fully featured chat application designed for the XMPP protocol,. It is developed by volunteers using Python and GTK, making it compatible across Windows, MacOS, and Linux.

Here is a summary of its principal functionalities:

Core Communication and Privacy

• Encrypted Conversations: Gajim provides state-of-the-art end-to-end encryption for messages, pictures, and files to ensure they remain private between the users.

• Cross-Device Synchronization: Users can choose their preferred provider and synchronize their chats across all their devices.

• Interoperability: The app is designed to be interoperable with many other chat applications, allowing for a flexible communication experience.

Expressive and Social Features

• Rich Messaging: Beyond standard text, users can record voice messages, use reactions, send replies, and share status updates.

• Media Support: Recent updates have introduced previews for GIFs and similar animation formats, as well as improved file transfer capabilities.

• Group and Community Management: The tool supports group chats for organizing events or staying in touch with friends, as well as the ability to build communities around shared interests. It also features read markers within group chats to track conversation progress.

Technical and Community Aspects

• Open Source Development: The software is built and maintained by a community of volunteers and is available for translation and code contributions.

• Free and Accessible: Gajim is free software supported by user donations.

• Integrated Support: Users can join a dedicated XMPP chat to ask questions, share ideas, or report issues directly to the developers.

Gajim acts like a secure, community-built post office for the digital age: you are free to choose which branch (provider) you use, but regardless of your choice, your letters are locked in a high-security vault (encryption) that only the recipient can open, even if you are accessing your mailbox from different cities (devices).
