Domain Checker Pro

Version 1.2.0 | Stable Production

A professional-grade, multi-provider bulk domain availability aggregator. Built as a Chrome Extension (Manifest V3), it combines high-speed API checks with "battle-proof" DOM scraping to ensure 100% accurate results.

🚀 Key Features

• Persistent Session Memory: Never lose a scan again. Scans are automatically saved to your local browser storage. You can safely close the extension, return later, and view or export your historical data.
• Dynamic Grid Analytics: Results are rendered in a clean, multi-dimensional table, giving you a bird's-eye view of keyword availability across multiple extensions simultaneously.
• Smart Filtering & CSV Export: Filter results instantly by specific TLDs, and export your curated data directly to a .csv file for Excel or Google Sheets integration.
• Multi-TLD Matrix Scanning: Generate hundreds of combinations instantly by scanning multiple selected TLDs concurrently against your base keywords (includes custom TLD injection support).
• Multi-Strategy Engine: Toggle between high-speed API checks and deep-scan browser scraping.
• Production-Ready Providers:
  • Public RDAP (API): High-speed, official protocol for rapid bulk testing.
  • Hostinger (Scraper): Advanced DOM validation using CSS success/taken badges.
  • Namecheap (Scraper): Isolated article scanning to prevent "alternative suggestion" false positives.
  • GoDaddy (Scraper): Precise data-cy attribute targeting and ARIA accessibility checks.
• Process Control: Integrated Kill Switch (Stop Scan) and visual spinners for real-time status tracking.
