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.
