Bulk HTTP Status Checker

Free, no signup. A site migration or audit turns up hundreds of URLs to check, one at a time is not an option. Paste up to 500 and get status codes, full redirect chains, and final destinations, with the SEO problems already flagged.

Built by Patrick Stox

Advanced: safe request headers

Up to 5 response-negotiation headers: Accept, Accept-Language, Cache-Control, and Pragma. Credentials, cookies, and X-* headers are refused. Headered checks are never cached or stored.

Request user-agent

A matching user-agent does not make this request originate from that crawler’s verified IP range.

Example data — replace with your own, then press Check status codes

Checks run from our server; we fetch the URL you enter and don't keep the results. Re-running the same list within about ten minutes reuses a short-lived cache. Checks with custom headers deliberately bypass that cache. Anonymous run-level outcome counters may be used for aggregate research; URLs, domains, IPs, and identifiers are never included, and no statistic is released below 100 runs.

Sample report Illustrative status inventory — not a company audit
 
Say you paste four URLs:
 
 
https://example.com/old-trail-shoe
https://example.com/products/trail-runner
https://example.com/products/retired-boot
https://example.com/dead-link
 
 
…and the checker returns:
  
     
  • Two pages return 200 — that confirms successful HTTP responses, not
            necessarily healthy or indexable content. Inspect titles and rendered copy before calling
            either URL clean.
    •  
  • One URL cleanly 301-redirects. https://example.com/old-trail-shoe lands on
https://example.com/products/trail-runner in a single hop (green→amber dots show it) — expand the row for
            the full chain detail.
    •  
  • One is a dead 404, flagged in red as a broken link — the row most worth fixing
            first, since every internal link pointing at it is wasted.
    •  
  • Sort by status or expand any amber/red row to triage a big list fast instead of
            reading every line — see HTTP status codes for what
            each class means for SEO.

Soft-404 trap: green status, missing product
 

Suppose /products/retired-boot returns 200, but its title is
          “Product unavailable” and its body is the same empty shell used by thousands of retired
          SKUs. This checker correctly reports the HTTP response as successful; it does not pretend
          that status alone proves useful content. Cluster repeated titles/body templates with a
          crawler, inspect representative rendered pages, and confirm Google's classification in
          Search Console. The `.example` URL and scenario are illustrative.

 
 
 
How to use it
 
     
  1. Paste your URLs into the box, one per line — up to 500. The scheme is optional; a bare
example.com/pricing is treated as https://. Duplicate lines are removed
            automatically.
    2.  
  2. Or press Import sitemap, paste a sitemap.xml URL, and the tool
            pulls every <loc> into the list for you (capped at 500).
    3.  
  3. Pick the user-agent — default, browser, Googlebot, Bingbot, or the listed AI
            crawlers — if you want to compare an anonymous crawler response with a browser response.
    4.  
  4. For an opt-in content-negotiation check, open Advanced: safe request headers.
            It accepts only Accept, Accept-Language, Cache-Control, and
Pragma; credentials, cookies, and X-* headers are intentionally blocked.
            Those checks bypass the short-lived cache.
    5.  
  5. Press Check status codes. Results stream in per batch. Filter with the status
            chips (2xx / 3xx / 4xx / 5xx / error), sort by status, latency, or chain length,
            and expand any redirecting row to see every hop.
    6.  
  6. Use Export CSV for the full list — input URL, final status, final URL, redirect
            count, chain, latency, flags, and errors. Export a snapshot to compare a later run;
            the comparison calls out status changes, new 4xx rows, and chains that grew.
    7.  
 
 
 
       
     
       

Checks run from datacenter IPs at the edge — some bot-protected sites (Cloudflare
        challenges, WAFs, CDN bot rules) answer these requests differently than they would
        answer a real browser.

  
 
What the results mean
 
Every row's status pill is colored by its status class:
 
     
  • 2xx Success (green) — the URL returned a
            live page (usually 200). Nothing to fix.
    •  
  • 3xx Redirect (amber) — the URL redirects;
            the Final URL column shows where it lands. Expand the row for every hop.
    •  
  • 4xx Client error (red) — broken or missing
            (404), forbidden (403), gone (410). These are dead links to fix or remove.
    •  
  • 5xx Server error (red) — the server failed
            (500) or is unavailable (503). Often transient, worth re-checking.
    •  
  • ERR Connection error (red) — the request
            timed out, the host didn't resolve, or the site refused it.
    •  
 
Amber flags on a row call out specific redirect problems the tool detects, including:
 
     
  • Redirect chain — reduce to one hop — more than one redirect before the final page.
    •  
  • 302 in chain — a temporary redirect where a permanent 301 belongs, so signals
            never consolidate.
    •  
  • http → https → www multi-hop — a common canonicalization chain that should be
            collapsed to a single redirect straight to the final host.
    •  
  • Meta refresh — a client-side refresh on the final page that header-only tools miss.
    •  
  • Redirect loop and more than 5 redirects — shown as red error flags.
    •  
 
How it works
 

The page splits your list into batches of 25 URLs and posts them to a server-side checker (URL
          fetching can't run in your browser). Up to four batches run in parallel, and each result streams
          back into the table as it lands — you don't wait for the whole list to finish. For each URL the
          checker requests it without auto-following redirects, records the status and
Location at every hop up to five, and reports the final status and destination. It also
          reads the final HTML for a meta refresh.

 

Everything after the fetch — the status-class chips, sorting, filtering, and CSV export — runs
          entirely in your browser. No URLs are stored, and re-running the same list within about ten minutes
          reuses a short-lived edge cache.

Limitations
 

Checks run from datacenter IPs at the edge, so bot-protected sites (Cloudflare challenges, WAFs, CDN
          bot rules) may answer differently than they would a real browser — and choosing the Googlebot
          user-agent doesn't make the request pass reverse-DNS verification. It follows the HTTP
chain plus one layer of meta refresh, not JavaScript redirects (window.location,
          framework routers won't appear). Each chain stops at five hops. It only reaches pages a public crawler
          could reach — login-gated, IP-restricted, or private addresses are refused. And the 500-URL cap plus a
          courtesy limit of 10 URLs per host per batch mean very large single-site lists are spread across
          multiple batches.

 
Frequently asked questions
 
How many URLs can I check at once?
Up to 500 URLs per run. Paste them one per line, or import them straight from a sitemap URL. The tool splits the list into batches of 25 and deliberately paces requests to avoid overwhelming one host or the checking service, so a full single-site run can take a couple of minutes. Duplicate lines are removed before checking.
What is the difference between the status code and the final URL?
The status code shown is the final status — the code of the page the URL actually lands on after following any redirects. The Final URL column shows where a redirecting URL ended up. If a URL redirects, the tool follows the whole chain (up to five hops) and reports the destination, not the first hop. Expand any row to see every hop and its individual code.
Why is my status code colored red or orange?
Rows are colored by status class. Green is 2xx (success), amber is 3xx (redirect), and red is 4xx (client errors like 404), 5xx (server errors like 503), or a connection error. The color lets you scan a large list and spot the broken and redirecting URLs without reading every code.
Does it check the status code a crawler sees?
It can send the browser, Googlebot, Bingbot, GPTBot, ClaudeBot, or PerplexityBot user-agent string, which can surface crawler-specific rules. The request still comes from a datacenter IP, not that crawler's verified network, so IP-verifying sites may treat it as an unverified bot.
Are the URLs I paste stored anywhere?
No. URLs are sent to the checking endpoint only to fetch their status and are never saved. Filtering, sorting, and CSV export all run in your browser. Re-running the same list within about ten minutes reuses a short-lived cache so repeat checks are faster, but nothing is persisted to an account or database.

Araç hakkında
En fazla 500 URL için HTTP durum kodlarını, tam yönlendirme zincirlerini, son hedefleri, atlama gecikmelerini, yanıt başlıklarını ve canonical ipuçlarını inceleyin. Sonuçları filtreleyin, iki anlık görüntüyü karşılaştırın ve CSV dışa aktarın; kayıt gerekmez ve veri saklanmaz.
Özellikler
  • Her URL için durum kodu, toplam ve atlama başına gecikme ile son hedef görünümü.
  • 301/302 zincirlerinde her hop, konum başlığı ve nihai 2xx sonucunu açarak inceleme.
  • Canonical, robots ve yanıt başlığı kanıtlarıyla yönlendirme sistemindeki ipuçlarını filtreleme.
  • Site haritasından URL alma, anlık görüntü karşılaştırması ve kopyalanabilir CSV raporu.
Nasıl çalışır
URL listesini yapıştırın veya site haritasından alın. Her durumu, yönlendirme hoplarını, son hedefi ve gecikmeyi açın; canonical ile yanıt başlığı bulgularını kaydedin. Düzeltmeden sonra aynı listeyi yeniden çalıştırın, anlık görüntüleri karşılaştırın ve CSV raporunu ekibinizle paylaşın.
Sınırlamalar
  • İstekler herkese açık alma hizmetinden gelir; tarayıcı, Googlebot veya oturum açmış kullanıcıyla aynı sonucu garanti etmez. Özel kimlik doğrulama, cookie, X-* ve toplu tarama davranışı bilerek sınırlıdır.
  • Bir 2xx yanıtı sayfanın dizine girdiğini, içeriğin doğru olduğunu veya Google canonical seçimini kanıtlamaz. URL Inspection ve kendi sunucu kayıtlarınızla ayrıca doğrulayın.
Sık sorulan sorular
Araç kaç URL kontrol eder?
Bir çalıştırmada en fazla 500 herkese açık URL kontrol edebilirsiniz. Site haritası içe aktarma da bu sınır içindeki URL listesini oluşturur.
301 yönlendirme zinciri ne zaman temizdir?
Her beklenen hop açıkça izleniyor, son hedef doğrudan 2xx yanıtı veriyor ve gereksiz döngü veya ara zincir yoksa zincir temiz kabul edilir.
Sonuçlar Googlebot durumunu gösterir mi?
Hayır. Bu araç herkese açık bir alma hizmetinin gözlemlenen durumunu gösterir; Googlebot, tarama ve dizin kararları için doğrulanmış Search Console kanıtı gerekir.
Cookie veya kimlik doğrulamalı URL test edebilir miyim?
Hayır. Güvenlik ve gizlilik nedeniyle kimlik bilgileri, cookie ve X-* başlıkları gönderilmez; yalnızca herkese açık yanıt kanıtı incelenir.
CSV raporunu nasıl kullanırım?
Filtrelediğiniz görünümü CSV olarak dışa aktarın, hatalı durumları ekip kaydına ekleyin ve düzeltmeden sonra yeni bir anlık görüntüyle satırları karşılaştırın.
