Bulk URL Checker Software

Check status codes, redirect chains, and response times across thousands of URLs at once. Cloud-based, browser-only, no installs or server setup.

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

Why pick software over a desktop crawler

Desktop URL checkers like Screaming Frog tie up your local machine, fail under enterprise firewalls, and have hard limits on how many URLs they can process before slowing to a crawl. A cloud-native bulk URL checker delegates that work to dedicated workers.

You upload a CSV or paste a list, hit run, close your laptop, and pick up the results when they're ready. Jobs of 50,000+ URLs complete in minutes, not hours.

What the software actually checks

Every URL gets a full HTTP status check — 200/301/302/404/410/500, redirect chains followed end-to-end, response times measured, soft 404s detected by content heuristics.

  • HTTP status codes (2xx/3xx/4xx/5xx)
  • Final URL after redirect chain (with hop count)
  • Response time per URL
  • Soft 404 detection (200 with not-found content)
  • CSV export with every column you'd want
  • Filter results by status code, domain, or pattern

Built for ad-hoc audits AND recurring monitoring

For one-off audits — site migrations, backlink validation, content cleanups — pay-as-you-go credit packs from $9.99. No subscription required, credits never expire.

For ongoing monitoring of high-stakes URLs (your blog, docs, product pages), scheduled checks send a diff alert only when something has actually changed since last run. Coming soon — join the waitlist on the schedule page.

Frequently asked questions

Is this software or a web app?
It's a cloud-based web app — nothing to install. Open the site, paste or upload URLs, get results. No server, no desktop client, no enterprise IT approval.
How large can a single job be?
Up to 75,000 URLs in one job. Larger needs are handled by splitting across jobs or contacting us for higher limits.
How fast does it run?
Most jobs of 1,000-10,000 URLs complete in under 5 minutes. Larger jobs scale linearly with the worker pool.
Can I integrate it with my own scripts?
Yes — there's a public REST API and an MCP server for AI agents (Claude, ChatGPT) to drive the checker programmatically.
