Bulk URL Status Code Checker

Bulk URL Status Code Checker: Check Up to 500 URLs for Free

A single broken link is easy to spot. A hundred of them, scattered across an old sitemap, a migrated domain, or a client’s redirect map, are not. That’s the gap this tool is built to close: paste a list of URLs, and within seconds you get the HTTP status code, the full redirect path, response time, and any hidden issues for every single one — without opening a terminal, installing desktop software, or paying for a crawler subscription.

Why Checking URLs in Bulk Matters

Most site owners only discover a broken link when a visitor reports it, or worse, when it shows up as a crawl error in Search Console weeks later. By then, the damage — lost traffic, wasted crawl budget, a frustrated visitor bouncing off a 404 page — has already happened.

Bulk checking flips that around. Instead of reacting to individual errors, you audit your whole link list at once: internal navigation links, backlinks pointing at you, affiliate links, old blog post URLs, or a client’s entire domain after a migration. A five-minute check can surface problems that would otherwise take hours to find by clicking through pages one at a time.

What This Tool Actually Checks

Most free status checkers stop at a single HTTP status code. This one goes further:

• Initial and final status codes — see both what a URL returns on the first request and what it resolves to after every redirect.
• Full redirect chains — up to 5 hops, so you can see exactly how a URL gets from A to B, not just the end result. This matters because every extra hop in a chain adds latency and dilutes link equity for SEO.
• Soft 404 detection — a page can return a technically healthy 200 status while the content on the page actually says “not found.” Standard checkers miss this completely. This tool scans the response body for that language and flags it separately, so it doesn’t hide inside your “healthy” results.
• Response time — flag slow-loading pages before they affect user experience or Core Web Vitals.
• Key response headers — content-type, cache-control, server, ETag, last-modified, x-robots-tag, and HSTS, all pulled automatically for each URL.
• Built-in safety checks — requests to localhost and private network ranges (like 192.168.x.x or 10.x.x.x) are blocked automatically before they’re ever made, so a stray internal URL in your list can’t accidentally probe your own network.

How It Compares to Other Free Checkers

Free bulk URL checkers exist across the web, but most trade off one of two things: either they cap you at a small batch size, or they only report a bare status code and stop there. A quick look at what’s commonly offered:

• Many popular free tools cap out between 25 and 150 URLs per check before nudging you toward a paid plan or an account.
• Several report only the first status code returned, without confirming what the URL actually resolves to after redirects.
• Very few flag soft 404s, since it requires actually reading the page content rather than just the response header.

This tool checks up to 500 URLs per run, with no sign-up, and reports the redirect chain and soft-404 status alongside the basic status code — combining a generous free limit with diagnostics that are usually reserved for paid crawling tools.

Who This Tool Is For

SEOs and site auditors can use it to sweep a site’s internal links or a client’s backlink profile for broken URLs and redirect chains that need cleaning up.

Developers and webmasters can run it after a deploy or a domain migration to confirm that redirect rules are firing correctly and nothing is silently 404ing.

Content teams can check outbound links in old blog posts before a refresh, catching dead external references that hurt credibility and user experience.

Agencies can use it as a fast first pass before pulling out a full crawler like Screaming Frog — for a quick health check, this tool answers the “is anything broken right now” question in a couple of minutes.

How to Use It

1. Paste your URLs into the box, one per line — or upload a .txt or .csv file. Duplicates are removed automatically.
2. Click “Check URLs” and watch live progress as the tool works through your list in small batches.
3. Review the results table: status codes, redirect counts, final destinations, response times, and any flags.
4. Use the summary filters (Healthy, Broken, Redirects, 5xx, Connection errors, Non-2xx) or the search box to zero in on what needs attention.
5. Export the full report as a CSV, or copy the results straight to your clipboard to share with a team or client.

A Note on Privacy

URLs submitted to this tool are processed for that single check and are not stored or logged afterward. Once you close the tab, the results exist only if you’ve exported them — nothing is retained on our end.

Paste your first batch of URLs above and see the results in real time. No account, no watermark on your export, and no limit that forces you to split a reasonably sized list into multiple runs.

Mitigating SSRF Risks: Securing Private Cloud Infrastructure Against Rogue Link Testing A critical structural vulnerability present in unoptimized bulk link scanners is the lack of strict address filtration. Server-Side Request Forgery (SSRF) occurs when a web-based script accepts an arbitrary, unvalidated user input URL and forces the host server’s internal infrastructure to fetch it. If a bad actor pastes internal cloud endpoint paths (such as
http://169.254.169 or private subnets like 192.168.x.x), an unprotected checker will attempt to crawl them. This accidentally exposes internal network structures, AWS metadata tokens, or database ports. ToolsVale eliminates this vector completely by integrating a strict Client-Side SSRF Pre-Filter Validation Layer. Before our edge execution framework triggers an outbound connection attempt, the host string is verified against global private networking subnets. Any entry pointing toward localhost or localized network ranges is immediately intercepted and blocked with a blocked_host code directly inside your dashboard browser tab—ensuring web
infrastructure stays completely isolated from rogue network scanning loops.

The Silent Rank Drain: Identifying and Eliminating Soft-404 HeadersA standard Hard 404 occurs when a server cleanly tells a visiting spider that a document is gone by outputting a structural 404 Not Found response code. A Soft 404, however, is a deceptive layout state: the server sends an optimistic 200 OK network signal to the search bot, but the actual visual text painted on the layout reads “Error: Page Not Found” or “Product Out of Stock”. Because traditional programmatic crawlers only review raw HTTP header responses, they mark these lines as completely healthy. This leaves zombie index pages floating inside Google’s database, burning your site’s crawl budget and diluting search equity. The ToolsVale Bulk Status Checker circumvents this issue by running an integrated Text String Sniffer across the initial data packet. Our script reads the body text of the page payload, matching structural language arrays against common soft-404 error profiles. If an anomaly matches, the dashboard immediately flags the URL as a Possible Soft 404, allowing you to fix page templates before search engine bots suppress your index signals.
