🛡
14-Day Money-Back Guarantee. We built SilkCrawl because existing tools were either overpriced subscriptions or lacked the depth we needed for real audits. We're confident it delivers — but we also know that confidence means nothing until you've tested it on your own sites.

That's why every Pro license comes with a straightforward 14-day refund policy. Buy it, run it against your toughest crawl, dig into the reports. If SilkCrawl doesn't earn its place in your workflow, email [email protected] within 14 days and we'll refund you in full. No hoops, no forms, no "tell us why" questionnaire. One email, full refund, same payment method.

We'd rather have you try it risk-free than wonder "what if." Most people who test it, keep it.
