What "mass" actually means

When backlink lists hit 50,000 entries and migration sitemaps cross 25,000 URLs, you need a tool that doesn't flinch. We process up to 75,000 URLs per single job, scaling out across worker nodes, your laptop is uninvolved.

Mass-validation use cases

Backlink profile audits, validate every backlink Ahrefs or SEMrush reports for your domain.

Site migration QA, verify the entire pre-migration sitemap returns the right redirects on the new structure.

Domain portfolio monitoring, check the homepage and key landing pages of every domain in a portfolio.

Content audit, feed in every article URL plus every link they reference, find what's broken.

Performance at scale

A 50,000-URL job typically completes in 10-15 minutes. Domain-aware throttling prevents hammering any single host. Soft 404 detection runs at scale without slowing the job.

Frequently asked questions

Beyond 75,000, what then?
Split into multiple jobs (each up to 75,000) or contact us at the higher limits if you have a recurring need beyond that.
Will my list be private?
Yes. Submitted URLs are processed and stored only for your account. We don't share, sell, or repurpose them.
Can I share results with my team?
Public report URLs (shareable read-only links) are shipping soon. For now, export the CSV and share that.
