ZAL fits every need

Everyone who wants to create a Zimbra extension can do so using our library.

  • Open ZAL is an Open Source library released under GNU GPLv2.
  • You can modify the ZAL according to your needs, as long as you respect the GNU GPLv2 license.
  • Documentation is available in the Wiki ZAL on GitHub or via Doxygen.

Are you a developer?

ZAL supports any Zimbra release equal to or higher than 6.0.7. If a new Zimbra version is released, download the latest version of ZAL so that your extension will be immediately compatible.

Your ZAL-based extensions are autonomous from the ZAL included in Zextras Suite and Zimbra Network Edition.

You can use more than one ZAL-based extension on your Zimbra server. Each extension uses a dedicated instance of the library.
