Domain Details
The Privacy-First Domain Research Platform
Domain Details is a comprehensive domain information and research platform designed with privacy at its core. Unlike traditional WHOIS lookup tools that track your searches and monetize your data, Domain Details stores everything locally on your device by default—your research stays yours.
Core Philosophy
🔒 Privacy-First Architecture
Local-First Design — All searches stored on your device, never shared unless you choose to sync
Direct Registry Access — Data fetched straight from domain registries, no intermediaries logging your activity
RDAP Protocol — Modern, standardized protocol replacing legacy WHOIS with structured data and built-in privacy protection
No Tracking, No Ads — Privacy-respecting business model that doesn't monetize your searches
