There's an app called Wappler that was developed by the same folks from DMXzone, which was quite well-known for its Dreamweaver add-ons at the time. It's the closer you will find of a direct successor.
Webflow ? Squarespace ? I assumed that segment had been occupied by CMS and SaaS companies.
Absolutely Squarespace (and WordPress). Non-technical website maintainers don’t want an HTML editor; they want their website to have an edit button.
I tried out Webflow this past week was a pretty enjoyable experience took me back to Dreamweaver days a bit.
I doubt it's worth it since you can get the same results in a few hours with Tailwind.
