Redirect Sniffer

Redirect Sniffer is a web-based URL redirect checker, link unshortener, and monitoring service. Paste a raw or shortened URL to reveal its complete redirect path, HTTP status codes, response times, and final destination without executing page scripts. The free checker requires no account and supports more than 100 common shorteners. Pro adds bulk audits for up to 200 URLs, 25 hourly, daily, or weekly monitors, email and in-app change alerts, one year of searchable history, crawler profiles, CSV exports, 10,000 API checks per month, and secret-value redaction.

It helps marketers, developers, affiliates, agencies, and QA teams find broken redirects, loops, slow hops, and unexpected destination changes.
