About vanity hosting
You are running on a vanity hosting service, when your provider only supports one specific software.
Certain software can have certain requirements on hosting. For a CMS it might be beneficial to have integrated caching and image delivery, as well as automatic software updates. While there can standard solutions for this, with specialized hosting this is integrated.
Vanity hosting is not an official term. It's something we made up.
For WordPress there are of course plenty of vanity hosting services, since it has such a big market share and it's so easy to make WordPress slow. Flywheel and WP Engine come to mind. For Typo3 Jochen Weiland and Mittwald are to be mentioned.
Sometimes, vanity hosting is the business, while the free software is the inbound marketing channel. In other words, software creators are monetizing their user base. You can say that about Laravel Cloud, Craft Cloud, Symfony Cloud, Shopware Cloud and others.
