With Managed WordPress Hosting, you can also set up a simple non-WordPress PHP script alongside your WordPress site, but we do not provide support for non-WordPress scripts and applications in Managed WordPress Hosting.
With Application Hosting, you can host pretty much any application (not just PHP) with us. We do not provide development support for applications, but we can assist with troubleshooting platform issues, default deployment features, adding domain names, and connections between Kinsta-hosted applications and databases.
