The main point is:
You should use Pinegrow Web Editor with WordPress theme builder if you do most of HTML and CSS editing mainly with Pinegrow, possibly in combination with code editor like Atom or VS Code.
But if you want to (mainly) use other website builders - especially those that export the HTML code like Webflow does - then Pinegrow Theme Converter can be the perfect solution for you.
The difference between these two apps is that Theme Converter stores WP actions outside of HTML source, thus making it possible to easily re-export HTML code from a different website builder app.
