Staging sites are advertised on the pricing page and by staging you mean we could publish a site to the custom url and then be making changes and not publishing or publishing to the .webflow.io address…correct?
Yes that is exactly right. If you are hosting using a custom domain, when you publish you have the option to publish to the custom domain, subdomain or both. Publishing to the subdomain is the webflow.io address which allows you to test the site before it goes live on the main URL.
