Proxy browser versus normal browser
A proxy browser route can fetch a public page through another server, while a normal browser connects directly and runs the site's scripts. Unblock Web focuses on safer previews instead of full interactive browsing.
Proxy browser versus VPN
A VPN routes device traffic through another network. A web gateway only handles specific web requests entered into the form and applies content safety rules.
What works best
Public articles, documentation, references, and simple pages usually work better than interactive applications.
