About Domain & Stack Inspector

Domain & Stack Inspector is a lightweight side-panel tool for anyone who checks websites for a living — developers, SEO/marketing consultants, agencies, or the curious. Open the side panel on any site to instantly see: Domain Details: Expiry date (colour-coded by urgency), registrar, domain age, and nameservers via public RDAP lookup. Hosting & Location: Provider (ISP/ASN) and server location via public geo-IP lookup. Tech Stack Detection: 46+ signatures covering popular frontend frameworks, major CMS/e-commerce platforms, payment gateways, chat widgets, marketing tools, analytics, and CSS frameworks. Server & Infra Signals: HTTP response headers (Server, X-Powered-By, CDN) to identify web servers, backend runtimes, and hosting CDNs. All DOM-based technology detection runs locally in your browser. The header module performs a single local fetch of the active page's URL to read response headers without requiring additional permissions. The only external calls are to rdap.org and ipwho.is.
