Adding webflow to an external site-

Hello!
I am involved in a live online streaming project (fitness). Anyhow we have a custom-built react site that is taking care of 80% of business. But there are a number of pages that we need to have some kind of cms attached to, things like FAQ’s, contact us, etc, you get the idea.
I am a big fab of webflow but am unsure of how it would work (if it could work), building those pages in webflow and then connecting them to the main site.
Any advice would be well received.

To leverage the CMS features of Webflow, you would need CMS hosting. So unless you can implement your react code on Webflow, this won’t work. You could choose to have the content (webflow) on the www subdomain and move the react code to a new subdomain or vice-versa.
