Server

eZ software is built to rely on existing technologies and standards. The minimal setup is PHP, MySQL/MariaDB, and Apache/Nginx. Recommendation for production setups is to use Varnish, and Memcached, NFS and Solr in a clustered setup.

For supported versions of these technologies see Recommended and Supported setups below.

Recommended setups

These setups are tested by QA and are generally recommended setups. For security and performance we furthermore recommend use of the newer versions of components below.

Development & Experimental setups

eZ Platform, the foundation of all eZ software, can theoretically run and execute on many more setups than the ones listed as recommended and supported, including any operating system supported by PHP, on a PHP 5.5 version or higher that pass the Symfony requirements, using cache solutions technically supported by Stash, using databases supported by Doctrine DBAL, and using a binary file storage solution supported by FlySystem.

Examples of Development setups:

OS: Windows, Mac OS X
Filesystem: NTFS, HFS+

Examples of Experimental setups:

OS: Any system supported by PHP
Persistence Cache: Redis
Filesystem: BTRFS, AUFS, ...
Databases: Postgres, MSSQL, Oracle ^{(As in technically supported by Doctrine DBAL which we use, but none supported by our installer at them moment, and Oracle and MSSQL is not covered by automated testing)}

While all these options are not supported by eZ Systems, they are community supported, meaning contributions and efforts made to improve support for these technologies are welcome and can contribute to the technology being supported by the eZ Systems team in the future.

Client

eZ software is developed to work with any web browser that support modern standards, on any screen resolution suitable for web, running on any device. However for the Editorial and Administration User Interfaces you'll need; a minimum of 1024-by-768 screen resolution, a desktop or tablet device, and a recommended/supported browsers found below.

Recommended browsers

These setups have been undergone some additional manual testing and is known to work.

Mozilla® Firefox® most recent stable version ^(t^{ested on Firefox}⁴²⁾
Google Chrome™ most recent stable version ^(t^{ested on Chrome}⁴⁷⁾

Microsoft® Internet Explorer® 11, Edge® 12, or higher ^{(tested on IE 11)}

Supported browsers

Apple® Safari® most recent stable version , desktop and tablet^{(Safari 9 or higher)}
Opera® 32, or higher, desktop and mobile

Please note that the user interface might not look or behave exactly the same across all browsers as it will gracefully degrade if browser does not support certain features.
