You can host HTML sites at Kinsta. With Managed WordPress Hosting, if the default WordPress index.php isn’t found in the /public directory, the server will automatically load index.html. If a different page is used for the website’s homepage, you’ll need to open a new chat with our Support team, and they can add a special rule on the server for this to work properly. Note: we don’t provide any additional support for non-WordPress sites for Managed WordPress Hosting.
You can also host practically any application or site with Application Hosting, including HTML sites and static generated sites.
