All plans include the core redirect inspection engine. No account needed for Free.
Every hop is displayed with its status code, Location header, query string, and any changes from the previous hop.
See which parameters survive each hop and which get dropped or rewritten — the most common silent breakage in campaign links.
Any hop served over HTTP is flagged in red. A chain that ends on HTTPS but passed through plaintext is still a credential leak.
Chains are capped at 10 hops. If a URL repeats, Hopcheck stops and reports a redirect loop. The page clearly distinguishes a completed chain from a truncated one.
