To run WordPress we recommend your host supports:
PHP version 7.4 or greater.
MySQL version 5.7 or greater OR MariaDB version 10.4 or greater.
That’s really it. We recommend Apache or Nginx as the most robust and featureful server for running WordPress, but any server that supports PHP and MySQL will do. That said, we can’t test every possible environment and each of the hosts on our hosting page supports the above and more with no problems.
For detailed PHP extension recommendations, see the Hosting Handbook.
Note: If you are in a legacy environment where you only have older PHP or MySQL versions, WordPress also works with PHP 5.6.20+ and MySQL 5.0+, but these versions have reached official End Of Life and as such may expose your site to security vulnerabilities.
