I’ve spent weeks diving into the leading technology detection platforms to figure out which ones actually help uncover what websites are built with — and which ones just look good on paper.
These tools reveal everything from hosting providers and analytics platforms to frameworks, CRMs, and payment systems.
They’re used by sales teams, market researchers, agencies, and anyone who wants to understand a company’s digital DNA.
I tested each tool based on accuracy, ease of use, pricing, and overall value.
Let’s get straight into it.

My Experience
IntelBee felt modern and purpose-built. The dashboard is simple enough for everyday use, yet powerful enough for team workflows.
