Wappalyzer and BuiltWith alternative
The tech stack, and who to talk to about it.
Wappalyzer and BuiltWith tell you what a site is built with. Data Scout detects the stack too — and puts it next to the company overview, the people and contacts the company publishes, and a scored site audit, so a technology lead becomes a conversation.
Or add the free Chrome extension — no account needed.

More than a list of technologies
Company overview
Name, industry, size, location and a business summary for any domain.
Contacts and people
Business emails, phone numbers and social profiles the company publishes, plus the names and roles on its team pages — each with its source.
Technology detection
The stack behind the site — CMS, frameworks, analytics, payments, infrastructure — with a confidence score per match.
Site audit
One 0–100 score across SEO, performance, accessibility, security and broken links, with the evidence behind every point.
AI insights
A summary, an opportunity score and a first line for your message, grounded in what the audit found.
When the other tool fits better. BuiltWith and Wappalyzer are the better fit for market-wide technology lists — every site on the web running a given product, with history. Data Scout is built for the next step: one company at a time, from its stack to the person to contact.
