can webflow be used as a front end?

It depends on what webflow let you export,if search Code export

On paid Workspace plans, you can export your site’s HTML, CSS, JavaScript, and assets from inside the Webflow Designer

So the design part should be ok,backend like database will not be exported .
So can add database later,eg i like Flask-SQLAlchemy.
I done many test with exiting templates sites and then plug in database to that code.
