Wappalyzer
Wappalyzer is a utility that uncovers the technologies used on websites, including content management systems, e-commerce platforms, web servers, JavaScript frameworks, analytics tools, and more.
The go-to tool for tech-stack prospecting, but meaningful volume requires committing to a $250/mo+ plan.

Wappalyzer — website technology profiler and B2B lead intelligence platform.
Wappalyzer is far more than a browser extension — it's a full technology-intelligence and lead-generation platform used by sales and marketing teams to identify companies by the tech stack they run. The DB lists it as 'Free' with no paid tiers, which is inaccurate: paid plans start at $250/mo (Pro) and reach $850+/mo (Enterprise), with only a thin free tier offering 50 lookups/month. It belongs in Sales Intelligence and Market Research as much as Browser Tools.
Wappalyzer has the broadest tech-detection coverage in its class and pairs it with built-in email verification and lead exports — avoiding the need to stitch multiple tools together for a basic tech-stack prospecting workflow.
The free tier's 50-lookup cap is exhausted almost instantly in any real prospecting workflow, and the jump to $250/mo is steep. API credits also expire after 60 days, punishing irregular usage.
