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.
