If you've ever tried to Google "bulk url redirect checker" and immediately found seven tools that all claim to be the best one, welcome. This happens with basically every SEO tool category, and redirect checking is no exception. Most of these tools are actually decent. The differences that matter are narrower and more practical than the marketing copy suggests: how many URLs can you check at once, can you export the results, does it follow full chains, and can you schedule it to run again later without you remembering to do it manually.
This post walks through the tools worth knowing about, what each one is actually good at, and where each one falls short — so you can pick based on your situation instead of whichever tool has the flashiest homepage.
I've used most of these tools myself across different migrations and audits, and the honest truth is that no single one wins at everything. The right pick depends on how many URLs you're dealing with, whether you need this once or on an ongoing basis, and whether you already pay for a broader SEO platform that happens to include redirect checking as one feature among many.
What to evaluate a bulk redirect checker on
Before getting into specific tools, here's what actually differentiates them in practice.
URL limits. Free tiers almost always cap how many URLs you can check in one batch or one month. If you're auditing a two-thousand-URL migration, a tool with a 500-URL free cap either needs multiple runs or a paid upgrade.
Export formats. You need the results in a spreadsheet you can filter, sort, and share with your team — not just a webpage you have to scroll through. CSV export is the baseline; anything less makes a large audit painful.
Chain detection. Some tools show you only the first hop and the final destination. Others show every single hop in between, including the status code at each step. For catching redirect chains, you need the full picture, not just the endpoints.
Scheduling. A one-time migration audit doesn't need scheduling. Ongoing monitoring does. Tools that can automatically re-check your important URLs on a recurring basis save you from having to remember to run a manual check every month.
With those four criteria in mind, here's how the main options stack up.
Screaming Frog SEO Spider
Screaming Frog is the closest thing to an industry standard for bulk redirect auditing, and it's the tool most technical SEOs reach for first. It's a desktop application (Windows, Mac, Linux) that can either crawl your entire site following links the way a search engine would, or accept a pasted or uploaded list of URLs in "list mode" for a more targeted check.
Once a crawl finishes, you get full status codes for every URL, complete redirect chain mapping through its dedicated Redirect Chains report, and loop detection built in. Everything exports cleanly to CSV or Excel for further analysis.
The free version crawls up to 500 URLs, which covers small sites and small-scale spot checks but won't get you through a proper migration audit on anything beyond a modest site. The paid license runs about $259 per year and removes the URL cap, adds scheduling, and unlocks additional configuration options like custom extraction and JavaScript rendering.
Where it falls short: it's a desktop tool, so it needs local installation and uses your own machine's resources for large crawls, which can be slow on bigger sites. It also doesn't have built-in alerting if a redirect breaks later — you have to manually re-run the crawl to catch new issues.
Best for: large migration audits and technical SEOs who already use it for broader site crawls.
Ahrefs Site Audit
Ahrefs' Site Audit tool crawls your site and reports on redirects as part of a much broader technical SEO audit that also covers broken links, duplicate content, and dozens of other checks. Its Internal Pages and External Pages reports let you filter by HTTP status code, including the 3xx redirect range, and it flags redirect chains and loops within that same crawl data.
The advantage here is context: because Ahrefs also tracks your backlinks, you can cross-reference which broken or chained redirects are sitting on pages that actually have external link value, which helps you prioritize fixes by real-world impact rather than guessing.
The downside is cost and scope. Ahrefs isn't a standalone redirect checker — it's a full SEO platform, with plans starting around $99 per month for the Lite tier. If redirect checking is genuinely all you need, this is a lot of tool (and cost) for one job. It makes more sense if you're already using Ahrefs for keyword research, backlink tracking, or competitor analysis and want redirect auditing bundled into that existing workflow.
Best for: teams already paying for Ahrefs who want redirect data cross-referenced with backlink and traffic value.
Semrush Site Audit
Semrush's Site Audit works similarly to Ahrefs' version — a full site crawl that reports redirect issues alongside a wide range of other technical SEO checks. It flags redirect chains, loops, and redirects pointing to 404s, and gives you a prioritized issues list that ranks problems by estimated impact, which is a nice touch if you're not sure where to start on a large list of findings.
Like Ahrefs, this comes bundled inside a broader SEO platform rather than as a dedicated redirect tool, with pricing starting in a similar range to Ahrefs' entry tier. The audit crawl can also be scheduled to run automatically on a recurring basis, which is genuinely useful for ongoing monitoring rather than one-off migration checks.
Best for: teams already using Semrush who want scheduled, recurring redirect monitoring without a separate tool.
httpstatus.io
httpstatus.io is a purpose-built web app for exactly this job, with none of the extra scope of a full SEO platform. You paste in a list of URLs, and it returns the status code, full redirect chain, and response headers for each one, right in your browser, no installation needed.
The free tier handles smaller batches and shows full chain detail, which is more transparency than most free tools offer. Bulk checking at higher volumes requires a paid plan, starting around $9 per month, which raises the URL limits and unlocks export options.
It's a lean, focused tool — which is exactly the point. If you don't need broader SEO audit features and just want a fast, no-nonsense way to check a batch of URLs and see their full redirect path, this is one of the more straightforward options available.
Best for: quick, focused bulk checks without needing a full SEO platform subscription.
Redirect Path (Chrome extension)
Redirect Path is a free browser extension that shows you the full redirect chain for whatever page you're currently viewing, directly in your browser toolbar. It's fast, it's free, and it requires zero setup beyond installing it.
The catch is right there in how it works: it checks one URL at a time, the one you're actively browsing. There's no bulk mode, no CSV upload, and no export function. This makes it a genuinely useful tool for quick manual spot-checks — confirming a single redirect fired correctly after you just set it up, for instance — but it's the wrong tool entirely for auditing hundreds of URLs.
Best for: quick one-off checks while you're already browsing, not bulk audits.
WhereGoes
WhereGoes is a web-based redirect tracer that shows a clear, hop-by-hop breakdown of a URL's redirect path, including status codes at each step. It's built for clarity — the visual chain display makes it easy to spot exactly where a redirect goes wrong, which is genuinely helpful when you're debugging a specific problematic URL rather than scanning a whole list.
It offers a free tier for individual checks, with a paid tier (roughly $12 per month and up) for higher volume use. Bulk support is more limited compared to dedicated bulk tools like httpstatus.io or Screaming Frog — it's built primarily around single-URL clarity rather than batch processing at scale.
Best for: debugging a specific problematic redirect chain in detail, less suited to large batch audits.
cURL (command line)
cURL is a free, pre-installed command-line tool on most Mac and Linux systems (and available for Windows) that can check redirects with zero third-party software. With a short script, you can loop through a text file of URLs, request each one, and log the status codes and redirect locations to an output file.
The appeal is total control and no cost: no account, no rate limits beyond what the target server itself imposes, and complete flexibility over exactly what data you capture and how you format it. For teams comfortable with basic scripting, this scales to any number of URLs without hitting an artificial cap from a vendor.
The tradeoff is setup effort. There's no visual interface, no automatic chain visualization, and no built-in export formatting — you're building the reporting layer yourself. This is the right tool if you have technical comfort with the command line and want a free, fully custom solution. It's the wrong tool if you want something usable in the next five minutes without writing a script first.
Best for: technical teams who want full control and zero cost, and don't mind scripting the reporting themselves.
Redirect-Checker.org and similar lightweight web checkers
Beyond the tools above, there's a category of simple, no-frills web checkers — Redirect-Checker.org is a good representative example — that exist purely to answer one question fast: where does this URL end up, and what status codes did it pass through on the way there?
These tools are lightweight by design. You paste in a URL (or sometimes a short list), hit check, and get a readable trace of the redirect path back instantly, with no account required and no software to install. Some support checking a handful of URLs at once, though rarely at the scale of a proper migration audit.
The appeal is speed and zero friction. If you're troubleshooting a single confusing redirect and just want a fast second opinion outside your primary tool, these lightweight checkers are a fine gut-check. They're not built to replace a proper bulk audit tool for anything beyond a small number of URLs, and most don't offer meaningful export or scheduling features.
Best for: quick sanity checks and troubleshooting individual URLs alongside your primary bulk tool.
How a bulk check actually plays out day to day
It helps to see how these tools fit into an actual workflow rather than just comparing feature lists in the abstract.
Say you're three weeks past a migration and want to confirm everything's holding up. You'd export your list of old URLs — pulled from your old sitemap and analytics data before the migration — and load it into whichever bulk tool you've chosen. If you went with Screaming Frog, that means switching to list mode and pasting or uploading the file. If you went with httpstatus.io, it's a paste-and-check in the browser.
Once the check finishes, you're looking at a spreadsheet or on-screen table with a status code, chain length, and final destination for every URL. The URLs that return anything other than a clean single-hop 301 to the correct new page are your action items. You'd then work through them by priority, using whichever secondary tool — WhereGoes, Redirect Path, or a quick cURL check — gives you the clearest hop-by-hop view for actually debugging why a specific one is broken.
This is also where scheduling earns its keep. If you set up an Ahrefs or Semrush crawl to run monthly, you get this same spreadsheet delivered automatically without having to remember to run anything. For a one-off migration, that's overkill. For an active site where URLs change regularly, it's the difference between catching a broken redirect within a month versus finding out six months later when someone finally complains.
Free vs paid — what's actually usable at scale
Here's the honest summary: free tiers across almost every tool in this list top out somewhere between a few hundred URLs and low thousands per check, or restrict how detailed the chain data is. For a small site redesign or a spot-check, free tiers are genuinely enough.
For a real migration — the kind involving a full site's worth of URLs, potentially in the thousands — you're looking at either a paid tool subscription, a scripted cURL approach, or running a free tool in multiple batches (which works, but eats more of your time than a single paid run would). There's no way around this tradeoff: bulk-checking a large site properly costs either money or your own time spent scripting around free limits.
Which tool for one-off migration vs ongoing monitoring
For a one-off migration audit, Screaming Frog is the strongest default choice if you're comfortable with a desktop tool, since its list mode, chain reporting, and export options are purpose-built for exactly this job. If you'd rather avoid installing software, httpstatus.io covers similar ground for smaller batches directly in the browser.
For ongoing monitoring — catching redirect issues that crop up between migrations, as part of regular site maintenance — a scheduled crawl through Ahrefs or Semrush makes sense if you're already paying for one of those platforms for other reasons. If you're specifically running a WordPress site and want redirect health checked automatically as part of broader technical SEO monitoring, rather than running a separate manual audit tool every quarter, a tool like RankHive folds that ongoing check into the rest of your site's automated SEO maintenance instead of treating it as a standalone task you have to remember to do.
FAQ
What's the single best free option for a small migration?
Screaming Frog's free tier, capped at 500 URLs, covers most small business site migrations outright. If your site is bigger than that, httpstatus.io's free tier is a reasonable secondary option for smaller batches, or you can run Screaming Frog's free crawl in stages.
Do I need a paid tool if I only have fifty redirects to check?
No. Fifty URLs fits comfortably inside almost every free tier on this list. Save the paid tools for when you're dealing with hundreds or thousands of URLs at once.
Can I combine multiple tools instead of relying on just one?
Yes, and it's often the smarter approach. A common pattern is using Screaming Frog or a scripted cURL check for the bulk crawl, then spot-checking a handful of specific problem URLs with something like WhereGoes or Redirect Path to see the exact hop-by-hop detail when debugging.
Does a bulk redirect checker also catch broken internal links?
Full-site crawlers like Screaming Frog, Ahrefs Site Audit, and Semrush Site Audit check far more than just redirects in the same crawl — broken links, duplicate titles, and other technical issues all show up in the same report. Narrower tools like httpstatus.io, WhereGoes, and cURL are built specifically for redirect and status code checking and won't give you that broader picture.
How do I check bulk redirects without installing any software?
Web-based tools like httpstatus.io and WhereGoes require no installation, just a browser. For real scale without installation, some SEO platforms also offer cloud-based crawls, though those come bundled with a broader (and pricier) subscription.
Is it worth paying for a tool if I only migrate a site once every few years?
Probably not as an ongoing subscription. Many of these tools offer month-to-month billing or short-term access specifically for this kind of infrequent, high-volume need — pay for one month around your migration, run your audits, then cancel. Free tiers combined with a bit of patience (running checks in batches) can also get most small migrations through without paying anything at all.
What export format should I look for?
CSV is the safe default, since it opens in any spreadsheet tool and is easy to filter, sort, and share with a team. Some tools also offer Excel or JSON export, which is useful if you're feeding the results into a script or a dashboard rather than reviewing them manually. Avoid tools that only let you view results on-screen with no export option at all — fine for a quick single check, unworkable for anything you need to act on systematically.
Do any of these tools check redirects on mobile versus desktop separately?
Most don't distinguish by default, since redirect rules at the server level typically apply the same way regardless of device. The exception is if your site uses device-based redirect logic (redirecting mobile visitors to a separate mobile-specific URL, for example), in which case you'd need to run your check with a mobile user agent specifically to catch device-specific redirect behavior. Screaming Frog and a few other crawler tools let you set a custom user agent for exactly this situation; simpler web-based checkers usually don't.
How do these tools handle HTTPS versus HTTP redirects?
Checking whether your HTTP URLs properly redirect to HTTPS is one of the most common use cases for these tools, and all of the ones covered here handle it the same way as any other redirect — reporting the status code and destination just as they would for any other hop. If you're auditing a domain that recently moved to HTTPS, make sure your URL list includes the HTTP versions of your URLs specifically, since that's exactly the transition you're trying to verify.
Can these tools check redirects on a site that's not live yet, like a staging environment?
Most can, as long as the staging environment is reachable from wherever the tool runs. Desktop tools like Screaming Frog can check a staging site sitting behind basic authentication, since you can enter credentials directly in the crawler. Cloud-based web tools often can't reach a password-protected or IP-restricted staging environment at all, since the request comes from their servers rather than your own browser. If you want to verify redirects before a migration goes fully live, a desktop tool is usually the more reliable choice for staging checks.
