WordPress MVC vs HTML to Wordpress: What are the differences?
Developers describe WordPress MVC as "WordPress framework for custom Themes and Plugins development". It is a framework for developing custom themes and plugins. It is free, Open Source, and will help you develop and deploy awesome themes and plugins faster and easier. On the other hand, HTML to Wordpress is detailed as "Cloud-based tool that converts your current HTML based website into a Wordpress theme". Htmltowordpress.io is a cloud-based tool that converts your current HTML based website into a Wordpress theme in seconds. Same site, same content, just as an editable Wordpress theme. If you have at least one html file you are ready to start the conversion process.
WordPress MVC and HTML to Wordpress belong to "CMS Tools" category of the tech stack.
