System Requirements

Before you dive into Sylius, your local environment must first meet some requirements to make it possible.

*nix-based Operating System (macOS, Linux, Windows [WSL only])
PHP 8.2or higher with the following extensions: gd exif fileinfo intl sodium
Composer
One of the supported database engines: MySQL 8.0 or higher MariaDB 10.4.10 or higher PostgreSQL 13.9 or higher
Node.js ^20 || ^22
Git

If you are planning to develop Sylius directly on your machine (without using e.g. containerization), it is recommended to install Symfony CLI and use Symfony Local Web Server.
