Technology stack


This page summarizes the technologies we use. For more detailed information, see the System Requirements.

Magento’s highly modular structure includes the following open-source technologies.

Web servers


  • Composer (dependency management package for PHP)

Magento, with assistance from our community, is implementing PHP 7.2 compatibility for our upcoming 2.3.0 release. Any backward-incompatibility issues will be resolved in this release, and all 3rd party libraries now support PHP 7.2. Fully tested 7.2 support will be delivered in following patch releases.

If you are interested in participating in Magento Community projects we welcome your help! See our ZenHub board for a full list of outstanding issues.

  • MySQL Percona

Additional technologies

Magento 2.2+ does not support HipHop Virtual Machine (HHVM).

Automated testing

Magento also provides automated testing suites that include unit, integration, functional and performance test scripts, as well as JavaScript tests and tools for static code analysis. Components include PHPUnit for the unit test framework and Selenium for the functional test framework.

This framework is located in the dev/tests directory. The functional testing framework mtf can be found in a separate repository. For more information, see the Functional Testing Framework guide.
