CompetitorFunnelSpyDigest
Enter a competitor's landing page, and optionally your own for a side-by-side. We pull the H1 and H2 positioning, every primary and secondary call to action and where it leads, lead-capture forms, social proof, and the ad and analytics pixels the page loads (Meta, LinkedIn, Google Ads, TikTok, X, Reddit, Microsoft). A monitor plan re-reads the page weekly and emails what changed.

AgencyProspectTearDown
For agencies and freelancers. Enter a prospect's URL: one read-only pass checks speed, mobile, schema, accessibility flags, social cards, SPF/DMARC, llms.txt, security headers and lead capture. The pack is a scored tear-down brief, 3 cold-email drafts and a 60-second video script that cite the real findings.

VendorStackWatch
Enter an account's domain for a free tech-stack snapshot from public DNS, SPF and page scripts. On a monitor plan, your named accounts (up to 100 or 500) are re-checked daily, and you see when a tool is added or removed: the switching window your competitors miss.

JobPostIntentRadar
