I've actually been able to reliably remove webflow and replace it
- with both bootstrap and Material-UI.
It's is serious PIA... and I wouldn't recommend it to those who fear blood.
I was mainly interested in the basic structure of the site...
- and not so much - the interactions (the fluff).
(in short: I wanted to use the Visual Design WYSIWYG advantages of Webflow...
then export the site - and add the fluff later)
Considering the structure... it is possible.
And long as you have a good string replacement process.
on a side note:
If you are interested... this thread may be worth following.
These 2 posts - in a way - are related.
In the above mentioned post... I was trying to have the Webflow library work with Material-UI
while dynamically add pre/externally defined interactions from a database using PHP/AJAX.
