Domain Availability Checker - Bulk Search

Bulk Domain Availability Checker for Multiple TLDs. Fast RDAP & Live Registrar Lookup with CSV Export & Local Saving.

Domain Availability Checker - Bulk Search Are you a domain investor, marketer, or developer tired of checking domain names one by one? Domain Availability Checker is a professional-grade, multi-provider bulk aggregator designed to automate your domain research. By combining the lightning speed of public RDAP APIs with battle-proof DOM scraping from top registrars (GoDaddy, Namecheap, and Hostinger), this extension delivers 100% accurate results directly to your browser. Best of all? It is completely private and local-first. Your keyword ideas never leave your machine, ensuring nobody can front-run your domain registrations. Key Features: Multi-TLD Matrix Scanning: Input a list of base keywords and instantly generate hundreds of combinations by scanning multiple domain extensions (.com, .net, .io, .ai) concurrently. Custom TLD Injection: Easily add and scan unlisted or niche TLDs (like .xyz, .co.uk, or .app) on the fly. Dynamic Grid Analytics: Ditch the messy text logs. View your results in a clean, multi-dimensional table that gives you a bird's-eye view of keyword availability across all selected extensions. Persistent Session Memory: Never lose a massive scan due to an accidental tab close. Scans are automatically saved to your browser's local storage. Return anytime to view, rename, or export your history. Smart Filtering & CSV Export: Instantly filter your grid to show only available domains, and export your curated data directly to a .csv file for seamless Excel or Google Sheets integration. Multi-Strategy Engine: Toggle between ultra-fast RDAP API checks or deep-scan browser scraping tailored for specific registrars to bypass false positives (like "premium alternative" suggestions). Process Control: Stay in control of massive bulk lists with an integrated Kill Switch (Stop Scan) and real-time visual progress monitors.
