WebDNA
Map a website's infrastructure, stack, brand system, and security posture in one report.
WebDNA is an open-source website intelligence scanner that turns a domain into a dense technical profile: DNS, SSL, IP ownership, hosting location, headers, CSP, detected technologies, social links, and visual identity.
The scanner starts network probes in parallel with HTML fetching, parses pages with Cheerio, falls back to a crawler proxy for blocked targets, and extracts practical brand tokens like colors, fonts, favicons, logos, and Open Graph assets.
It also includes WHOIS/RDAP and DNS propagation tooling, plus history and favorites, so repeated domain research feels closer to an investigation workspace than a one-off lookup.
