SiteIntelica vs TechStackIntel

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.

TechStackIntel is a technographics API for curated company technology-stack snapshots and taxonomy-backed lookups. Its launch catalog contains 200 curated company domains. GET /v1/lookup handles one domain, while POST /v1/batch/lookup accepts multiple domains through the same lookup pipeline. Responses include company data, cache status, schema version, evidence, and possibly product data. Anonymous access allows 60 requests per hour per IP. Free API keys allow 120 requests per hour, with grace up to 160 before the cap returns. Signup begins with an email magic link; keys can be sent using X-Api-Key or Authorization: Bearer, and GET /v1/usage reports usage. Canonical taxonomy slugs cover company.stack, with schema version 1.1.0 and confidence from 0 to 1. Research submissions accept taxonomy slugs, evidence, and optional products. Coverage is not guaranteed for every domain; missing snapshots return not-found. Curl commands, a thin CLI wrapper, JSON previews, and batch lookup are provided.
