  • The Swiften XMPP Client Library is supported on Mac OSX as well as the Windows and Linux platforms listed above.

In all cases the operating system must be updated with all available updates and patches from the operating system supplier. This can be important for the security of your system. Isode reserves the right not to support a system which is not up to date.

Compatible Web Browsers

The following web browsers are supported for Harrier, Cobalt, M-Link Edge and Icon-5066:

  • Latest version of Chrome.
  • Latest version of Firefox.
  • Latest version of Microsoft Edge.

These browsers should be updated with all available updates and patches.

Note: Internet Explorer is not supported.


In addition to all the server platforms, the Isode GUIs are fully supported on Windows 10.

Support of Evaluations

Isode strongly recommends that production services operate only on supported platforms, and that evaluations of Isode products are only undertaken on supported platforms.

Use of the Isode servers on Windows 10 is appropriate for simple evaluations and demonstrations. However, Isode does not support running the servers on these operating systems in a production environment. If you have questions about specific platform support, then please contact us.
