Xenu Link Sleuth is a free Windows desktop tool for manually checking broken links. StoreVitals is a modern, cloud-based ecommerce health monitoring platform that runs automatically on a schedule.
Xenu Link Sleuth was a great tool for its era — early 2000s desktop broken-link checking. For modern ecommerce stores that need automated, ongoing monitoring across SEO, security, and accessibility (not just broken links), StoreVitals is the better fit. If you occasionally need to crawl a very large site's links on a Windows PC and cost is the only concern, Xenu still works.
