Analyze pasted HTTP evidence
Choose the text you have: a redirect chain, redirect-rule example, response headers or sitemap URLs.
Analysis mode
Each mode runs locally in this browser tab.
Browser-only privacy note
This tool runs in your browser. Pasted text is processed locally. No live website request is made.
Do not paste secrets, private URLs, signed URLs, tokens, passwords or sensitive headers. NoNoiseTools does not need to store the pasted content.
Redirect chain analyzer
Paste curl -IL output, httpstatus.io-style text or simple URL/status lines. The parser reads the text only.
No live URL is fetched. Include status codes and Location headers where possible.
Used to flag final www, pages.dev or unexpected hosts.
Expected canonical scheme
Most public canonical URLs should end on HTTPS.
Redirect result
Plain-English notes from the pasted chain.
Waiting for pasted text
Paste redirect output above to analyze the final status, final URL, hops, hosts, path and query preservation.
- Final status
- Unknown
- Redirects
- 0
- Hops found
- 0
- Final URL
- Unknown
Paste a chain with status codes, URLs or Location headers to see the hop table.
What this tool checks
Use it for pasted redirect chains, redirect-rule examples, response headers and sitemap URL lists. It looks for final status, redirect count, Location targets, final host, HTTP vs HTTPS, www and pages.dev endings, dropped paths, dropped query strings, repeated URLs, common header notes and sitemap host consistency.
What this tool does not check
It does not fetch live URLs, follow redirects itself, read response bodies, crawl a website, scan multiple URLs, bypass CORS, check malware, validate every security header or replace a terminal, browser devtools, CDN logs or a production monitoring system.
Why this is browser-only
Browser JavaScript cannot reliably inspect arbitrary cross-origin status codes, redirect chains, Location headers or response headers because of CORS and opaque redirect behaviour. Instead of pretending otherwise, this tool analyzes evidence you paste from a trusted source.
How to get redirect data with curl
In a terminal, run:
curl -IL https://example.com/Copy the status lines and Location headers into the redirect chain tab. Keep private URLs, signed URLs and sensitive headers out of browser tools unless you trust the device and page context.
How to use httpstatus.io output
Copy the visible chain text from httpstatus.io or a similar checker, then paste it into the redirect chain tab. The analyzer looks for URLs, status codes and Location-like targets in the pasted text. It does not contact httpstatus.io or any other external API.
Privacy notes
This tool runs in your browser. Pasted text is processed locally, and no live website request is made from the analyzer. NoNoiseTools does not need to store pasted redirect chains, headers or sitemap content.
Do not paste secrets, private URLs, signed URLs, tokens, passwords or sensitive headers.
Key terms and assumptionsShort notes about browser-only analysis, pasted evidence, canonical defaults, header scope and privacy boundaries.
- Browser-only analysis
- The tool analyzes pasted text locally. It does not make live HTTP requests to arbitrary user-entered URLs.
- Text evidence required
- Redirect results depend on the pasted curl output, httpstatus.io-style chain, header text, sitemap XML or URL list.
- Canonical defaults
- The default expected host is nonoisetools.com and the default canonical scheme is HTTPS.
- Header scope
- Header notes are cautious checks for common redirect, cache, crawler and security-adjacent headers, not a full security audit.
- No secret handling
- Do not paste secrets, signed URLs, private URLs, tokens, passwords or sensitive headers into browser tools.
- No crawler
- The tool does not crawl sites, scan ports, fetch sitemaps, check bulk URLs or verify live server behaviour.

FAQs
Can this tool check a live URL?
No. It analyzes pasted redirect chains, headers, rule examples and sitemap URLs. It does not fetch arbitrary URLs or act as a live HTTP status checker.
Why not fetch the URL directly in the browser?
Browser JavaScript cannot reliably inspect arbitrary cross-origin status codes, redirect chains, Location headers or response headers because of CORS and opaque redirect behaviour.
What is a 301 redirect?
A 301 is a permanent redirect status. Browsers and search engines generally treat it as a long-term move to the Location target.
What is a 308 redirect?
A 308 is also a permanent redirect. Unlike older redirect codes, it is designed to preserve the original request method.
What is a two-hop redirect chain?
A two-hop chain means the URL redirects twice before the final page. It can work, but one clean redirect is usually easier to reason about.
Should www redirect to non-www?
Choose one canonical host and redirect the other version to it. For NoNoiseTools, the expected host is the non-www apex domain.
Should HTTP redirect to HTTPS?
For public websites, HTTP should normally redirect to the HTTPS canonical URL while preserving the path and query string.
What does it mean if query strings are dropped?
It means text after the question mark, such as tracking or filter parameters, did not survive the redirect. That may break shared links or campaign URLs.
