Swift

The client provides a graphical interface for XMPP messaging on macOS, Windows, and Linux, allowing users to set presence status, apply security labels, highlight keywords or phrases, and request message acknowledgments. Its design focuses on straightforward execution of common tasks while exposing advanced XMPP functionality through a clean layout.

It is built on the Swiften C++ SDK and the Stroke Java SDK, both of which are standards‑compliant, cross‑platform libraries for developing XMPP applications. These libraries serve as the backend for the client and are available under the GNU General Public License, with optional commercial support offered by the developer.

The software targets individuals and organizations that need a stable, secure, and adaptable XMPP solution, ranging from single‑user deployments to larger, security‑conscious environments. It is released as free software and is maintained in a stable maturity state.
