Tap a link and go straight to the destination. Unredirect is a Safari extension for iPhone, iPad, and Mac that skips redirect middlemen before they waste your time. It rewrites common "leaving site", link filter, jump, and redirect URLs into the real destination URL on-device. Why use it: - Skip "leaving this site" interstitials - Open supported redirect links directly - Use built-in rules for common redirect wrappers - Add your own rules for sites with a predictable redirect format - Keep everything local: no analytics, no servers, no browsing data upload Unredirect is built for people who notice the tiny delays and noisy handoff pages between a tap and the page they actually wanted. Enable the Safari extension once, then browse normally.
