Bulk Website Checker

Drop in a list of websites or specific URLs. We hit each one, report status, follow redirects, and export the results, fast enough for thousands of sites in one run.

Missing https:// is fine, we add it. Up to 200 URLs from this form.

Sign up on the next screen, your URLs come with you.

What we check: per site

For each website URL you submit, we report: HTTP status code, final URL after redirects (with hop count), response time, and any anti-bot block detection (403, 429).

You can submit homepage URLs (https://example.com) or deep-page URLs (https://example.com/specific/path). We handle both.

Common bulk-website use cases

Backlink validation, when Ahrefs reports 5,000 backlinks pointing at your site, paste the source URLs to verify they're all still live.

Competitor research, submit a list of competitor sites, find which are down or having issues during your research window.

Acquisition due diligence, verify the asset list of a domain portfolio before purchase.

Outbound directory cleanup, paste every URL your blog links to externally, find which third-party sites have died.

How fast and how many?

Up to 75,000 URLs per job. Most jobs of 1,000-10,000 URLs complete in under 5 minutes. We auto-throttle by domain so a list dominated by one host doesn't hammer it.

Frequently asked questions

Will you crawl pages on each site?
No, we check exactly the URLs you give us. If you want to check multiple pages on a site, include each URL in your list.
How do you handle sites that block bots?
We rotate residential proxies and respect robots.txt. Sites that hard-block return 403 or 429, which we report explicitly so you know it's a block, not a real broken site.
What's the largest list I can submit?
75,000 URLs in a single job. Beyond that, split into multiple jobs (each up to 75,000) or contact us for higher limits.
