In their own words
SiteIntelica
SiteIntelica is a web and API service for finding websites by their technology stacks and examining individual sites. Its X-Ray uses Wappalyzer Core to identify frameworks, content-management systems, CDNs, analytics tools, and advertising networks. Searches can find sites that use, or do not use, selected technologies, helping create prospect lists. Paid plans export matching results as CSV and can draft cold emails and sales briefs from scan data. Site monitoring covers technology changes, security regressions, and downtime, with email or webhook alerts. Site analysis includes security grades, CVE cross-referencing, Core Web Vitals, and on-page SEO audits. The REST API supports scans, contact extraction, lead searches, monitoring, and AI features, with limits set by plan. Documentation describes an MCP server for Claude or Cursor. The free plan provides five scans daily and previews five lead matches. Pro costs €19.00 per month; Business costs €49.00 per month.
