What TechnologyChecker is

TechnologyChecker is a technology intelligence platform for B2B sales, go-to-market, and market analysis teams. It detects 40,000+ technologies across 29.9 million live business domains, using signals that include HTTP headers, JavaScript fingerprinting, HTML parsing, and DNS lookups. Its detection covers backend infrastructure and standalone tools such as n8n, Zapier, Make, Airtable, Notion, and Coda. Historical timelines reach back roughly 20 years, combining recent crawls with analysis of public web archives. Real-time signals cover technology adoption, churn, and replacement changes.

The service also offers verified decision-maker contacts matched to technology signals, plus audience exports for LinkedIn, Facebook, and Google Ads. Its technographic API describes 29 REST endpoints for detection, company data, category share, and adoption, churn, and switch signals. Access is available through web, API, and a Chrome extension. The Free plan costs nothing and includes 100 lookups per month, six months of historical data, single-result CSV export, and basic company enrichment. Pro costs $89 a month, billed $890 a year; Scale costs $249 a month, billed $2,490 a year. Lookups pause when a plan's monthly limit is reached until the next billing cycle or an upgrade.
