What is it?
Domain Digger is a web-based toolkit for inspecting a domain's infrastructure. Enter a domain and it gathers DNS records, IP details with geolocation, and WHOIS registration data in a single view.
Beyond basic lookups, it can query DNS through several global servers and multiple resolvers to compare answers, and it visualizes DNS data on a map. It also offers a full and a quick WHOIS mode, and tracks SSL/TLS certificate history over time.
The app is built with React, Next.js and shadcn/ui, and is hosted on Vercel. It includes a bookmarklet for quick access and supports light and dark themes.
