Web hosting refers to storing all of your website files for your website, and delivering them to people who visit your website.
When someone visits your website at, e.g. YOURWEBSITE.COM, there needs to be a server listening for those requests, and then deliver the requested pages and artwork.
A simple analogy would be a mobile phone v. the phone company's mobile service. You need both the phone and the monthly service, in order to make calls.
Sygnal designs & builds websites primarily on Webflow, and uses Webflow's hosting service to deliver your website to the world.
Most websites make use of Webflow's CMS database, and without that, your website would not function.
Even if your website is completely a "static" website with no database, you'd lose the editor support, and would need a way to rebuild form submissions to allow clients to contact you by web form.
At best, your website would be quite handicapped, at worst, it wouldn't work at all. We don't recommend it.
