LibreCrawl Blog

Technical SEO guides, tool comparisons, and crawling tutorials

Welcome to the LibreCrawl blog, where we explore the technical side of SEO through the lens of open-source crawling. Whether you're deciding which crawler fits your workflow, learning to audit JavaScript-heavy sites, or scaling crawls to millions of URLs, you'll find practical guides written by people who actually use these tools daily.

We compare LibreCrawl against paid alternatives not to convince you we're superior, but to help you make informed decisions about which tool solves your specific problems. Sometimes that's LibreCrawl. Sometimes it's Screaming Frog, Sitebulb, or another crawler that better matches your needs. The goal is transparency, not marketing.

Every guide here comes from real-world experience crawling everything from small business sites to enterprise platforms with millions of pages. We write about the challenges we've faced, the solutions we've discovered, and the technical SEO principles that remain constant regardless of which crawler you choose.
