Find redirect chains, loops and duplicate sources
Redirect Map Checker analyzes a pasted redirect map for duplicate source URLs, self-redirects, multi-step chains, and loops without crawling the web. Review migration plans locally before implementation, keep sensitive staging URLs private, and catch costly mapping mistakes early. It is free and requires no account.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
