What is BuiltWith?
BuiltWith is a web analytics platform that provides detailed insights into website traffic, market share, and audience demographics. It offers a range of tools and data to help businesses understand their online presence and competitors.
Data sources
Our approach to sourcing tech usage data sets us apart from BuiltWith in a few key ways. First, we offer a broader technology catalog that includes not only web technologies but also CRMs, ERPs, databases, and various internal tools. BuiltWith focuses solely on web technologies.
Additionally, instead of tracking websites, we gather data from job postings. Each month, we collect job listings from millions of companies by monitoring company websites, job boards, and other hiring platforms. When a job listing mentions a specific technology in the title or description, it indicates that the company likely uses that technology. We then assign a Confidence Score (low, medium, high) based on the frequency and context of these mentions to estimate how likely the company is to use that technology.
Pricing
Our pricing model is also unique. While BuiltWith charges based on technology reports, we base our pricing on the number of companies returned in your search.
