Scan any website's tech stack and export B2B leads to a CRM-ready CSV. Stop manually inspecting page source to find B2B leads. StackSniper is a tech stack scanner and lead-generation tool for SDRs, web design agencies, and marketing founders. Click the icon on any site to see what it's built on: e-commerce platform, CMS, JavaScript framework, payment processor, email tool, ad pixel, and 50+ other technologies. Then export your findings to a CRM-ready CSV. CORE FEATURES Instant Detection: See the platforms and tools running on any site you visit, in one click. The Lead Queue: Add sites to a queue as you browse, then export the whole list at once instead of one at a time. CRM-Ready Exports: CSVs come pre-formatted with standard CRM import column headers, so there's no cleanup before you upload your list. Runs Locally: All scanning happens in your browser. Nothing is sent to an external server, and your lead data isn't tracked. HOW IT WORKS Click the StackSniper icon on any website to scan it. Click "Add to Queue" to save the lead. Keep browsing and queuing leads. Click "Export All" to download one CSV. A faster, cheaper alternative to bloated enterprise scanners, built for people who source leads by hand.
