Different Detection Methods, Different Data
Wappalyzer works by scanning the visible source code and HTTP headers of websites. This means it can detect frontend frameworks (React, Vue), CMS platforms (WordPress, Webflow), and analytics tools (Google Analytics, Segment) — but only what's exposed on the public-facing website.
TechStackMap collects data through verified sources: infrastructure platform customer lists, job postings mentioning specific tools, public dependency files, and curated research. This reveals the full internal technology stack — cloud providers, databases, AI models, observability tools, and more — that website scanning cannot detect.
If you're selling a database product and want to know which AI companies use MongoDB vs PostgreSQL, Wappalyzer can't help — databases aren't visible from scanning a website. TechStackMap provides this data directly.
Pricing: One-Time vs Monthly Subscription
Wappalyzer charges $250 per month ($3,000 per year). TechStackMap charges $49 as a one-time payment for lifetime access. For the annual cost of Wappalyzer, you could buy TechStackMap 61 times over.
When to Use Each Tool
Use Wappalyzer when you need to detect frontend technologies across a broad set of websites — for competitive analysis, website audits, or marketing technology research. Use TechStackMap when you need verified internal tech stack data on AI companies for sales prospecting, business development, or investment research.
Many teams use both: Wappalyzer for general website technology audits, and TechStackMap specifically for AI company prospecting. At $49 one-time, adding TechStackMap to your stack is a negligible cost compared to any monthly tool.
