Open Source Edition Downloads
Thank you for your interest in the Zimbra Collaboration Suite (ZCS) Open Source Edition!
ZCS Open Source Edition is available for you to test, evaluate, deploy, customize, and improve. In doing so we also hope you will participate in the Zimbra Community, so that we can work together to make ZCS a better product for everyone. It is free in perpetuity (providing you comply with the associated licensing terms). It does not, however, include Zimbra Support or software subscription.
The ZCS Open Source Edition software is provided in source code and binary formats:
- Use the ZCS software in source code format (under the terms of this Yahoo Public License (YPL) if you want to modify the software and create your own binaries (example: porting ZCS to a new platform)
- If you do not want to change the code or build your own binaries, use the ZCS Open Source Edition binary distributions instead (licensed under the terms of Zimbra Public End-user License Agreement (EULA); these are simpler to get up and running, and you are still free to redistribute unmodified copies
If you have questions about which ZCS product edition is best for you, or wish to purchase a subscription plus support to the ZCS Network Edition, please contact us.
More Tips:
- Can I revert the Network Edition Trial to the Open Source Edition? Absolutely, all your email data, etc. will be left intact if you choose not to purchase ZCS Network Edition
- ZCS is a server download are intended for administrators and developers. (Confused? Please see What Version of Zimbra is Right for Me?)
