Redirect Tab
We've added a Redirect Tab to lookups on BuiltWith - this works across the extension as well. It shows what other domains redirect to the domain, or if the domain redirects, where it redirects to.
The redirect functionality is a part of the Pro tools but we've put it in the indiviual lookups for everyone to use. Checkout one here - https://builtwith.com/redirects/boq.com.au
