Built for prospecting and competitive research
1,000+ technologies
Detect analytics, advertising, CMS, CDN, frameworks, and more using pattern matching across scripts, meta tags, cookies, and DOM elements.
AI-enhanced detection
Optionally use your Claude API key to identify technologies that pattern matching alone cannot catch, like tracking pixels and obfuscated scripts.
Custom fit profiles
Define matching criteria like "Uses HubSpot" or "Runs Ads" and instantly see which profiles match any site you visit.
Instant results
One click to scan. Technologies are grouped by category with version detection and confidence scores.
Privacy-first
No data collected by default. AI features only activate when you provide your own API key. All results stay local.
Chrome Extension (MV3)
Lightweight Manifest V3 extension. No background processes running when you're not using it.
Qualify prospects without leaving the page
