To achieve this, we needed to make sure it is based on the latest technology available.
Here are the system requirements you will need in order to use Elementor.
(If you are not sure whether or not your server support this, contact your host).
PHP 7 or Greater
Note: If your site is hosted on a server with an older PHP, you may experience issues. We recommend you to contact your hosting provider to upgrade to the latest version of PHP.
Elementor also works with PHP 5.4+, but these older versions have reached official End Of Life and as such may expose your site to security vulnerabilities and bugs.
MySQL 5.6 or Greater
MySQL version 5.6 or greater OR MariaDB version 10.0 or greater
WP Memory Limit
WP Memory limit of 64 MB or greater (128 MB or higher is preferred)

Please note that you can use Elementor with Safari, Chrome and Firefox. You will not be able to edit with Microsoft Edge and Microsoft Internet Explorer.
In any case, pages built with Elementor will show up in all the browsers.
It is not possible to edit with mobile phones and tablets for the moment. It is possible to work only with desktop computers.
If your website is hosted by WP Engine, you might need to add an SSL to your website to avoid saving issues.
If you use SiteGround, make sure that they modify the SubstituteMaxLineLength of your server for you: https://docs.elementor.com/article/219-502-error-when-i-try-to-edit-with-elementor
