Privacy And Limitations

Redirect mappings are analyzed locally in your browser and are not uploaded.

This tool checks mapping syntax and logic only; it does not test live server responses.
Environment-specific rule syntax differs across Nginx, Apache, and edge platforms.
Redirect chains and loops should still be verified with crawl testing after deployment.

FAQ

What row format is supported?

Use source|destination pairs, one mapping per line.

Does this confirm server-level redirects?

No. It validates mappings, not runtime HTTP behavior.

Can it detect duplicate source URLs?

Yes. Duplicate sources are flagged because they create ambiguous rules.

Should I redirect to parameterized URLs?

Usually avoid that unless parameters are intentionally canonical and stable.

Can this replace a full migration QA crawl?

No. It is a fast pre-check before full staging and production validation.
