MainWP runs on standard WordPress hosting. If your host supports WordPress and meets the [system requirements](/advanced/miscellaneous/mainwp-system-requirements), MainWP will work. Performance scales with your server resources, so Dashboard sites managing many Child Sites benefit from adequate memory, CPU, and PHP execution time. ## What You'll Learn * Recommended hosting providers for MainWP * Hosts that require additional configuration * How to address shared hosting limitations *** ## Recommended Hosts These hosts offer WordPress-optimized environments that work well with MainWP: [Pressable hosting logo](https://pressable.com/) **Pressable** - Managed WordPress hosting with MainWP-friendly configurations and strong performance for Dashboard sites. [GridPane hosting logo](https://gridpane.com/?via=mainwp) **GridPane** - Server management panel for WordPress, giving you full control over PHP settings and server configuration. [Cloudways hosting logo](https://www.cloudways.com/en/wordpress-hosting.php?id=125194\&a_bid=4869f424) **Cloudways** - Managed cloud hosting with easy access to PHP configuration, useful for enabling required functions. *** ## General Compatibility MainWP has no inherent size or speed limits. Performance depends on your server's configuration and resources. A slow or underpowered server affects plugin performance just as it affects WordPress overall. Before choosing a host: 1. Review the [MainWP System Requirements](/advanced/miscellaneous/mainwp-system-requirements) 2. Confirm the host meets [WordPress hosting requirements](https://wordpress.org/hosting/) 3. Check if the host allows required PHP functions (see [Required PHP Functions](/advanced/miscellaneous/required-php-functions-for-mainwp)) *** ## Hosts Requiring Additional Configuration Some hosting providers have security policies that require specific setup for MainWP to function properly: | Host | Configuration Needed | Documentation | | --------- | ------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------- | | WP Engine | Whitelist MainWP user agent for API access | [Deleting plugins on WP Engine](/troubleshooting/deleting-plugins-and-themes-not-working-on-the-wp-engine-hosted-child-sites-wp-engine-hosting) | | Cloudways | Enable tmpfile() PHP function | [Enable tmpfile on Cloudways](/advanced/miscellaneous/enable-tmpfile-php-function-on-cloudways) | | 20i | Whitelist MainWP Dashboard IP address | [Resolving 20i connection issues](/troubleshooting/how-to-resolve-issue-with-connecting-a-child-site-hosted-on-20i) | *** ## Shared Hosting Considerations Shared hosting environments sometimes limit PHP functions or maximum run time. If you experience issues: * Check if your host disables functions like `tmpfile()`, cURL functions, or `set_time_limit()` * Request function access from hosting support (see [Required PHP Functions](/advanced/miscellaneous/required-php-functions-for-mainwp)) * Consider enabling [optimized data loading](/dashboard/overview/how-to-optimize-your-mainwp-dashboard-for-shared-hosting) for Dashboards managing 30+ sites *** ## Firewall and Security Plugins Some hosts use web application firewalls (WAFs) that may block MainWP communication. If you have connection issues: 1. Check the [connection troubleshooting guide](/troubleshooting/potential-issues) 2. Review the [ports and user agent](/troubleshooting/what-port-and-user-agent-does-mainwp-use) that MainWP uses 3. Whitelist the MainWP user agent in your security rules *** ## Self-Check Checklist * [ ] Host meets MainWP system requirements * [ ] Required PHP functions enabled * [ ] No WAF blocking MainWP communication * [ ] Adequate server resources for number of child sites *** ## Related Resources * [System Requirements](/advanced/miscellaneous/mainwp-system-requirements) - Minimum requirements * [Required PHP Functions](/advanced/miscellaneous/required-php-functions-for-mainwp) - Function reference * [Optimize for Shared Hosting](/dashboard/overview/how-to-optimize-your-mainwp-dashboard-for-shared-hosting) - Performance tuning
