Could you build this?
Partial The UI and pattern filtering are simple, but creating a real-time availability and drop-catching index across hundreds of thousands of domains requires high-volume WHOIS/RDAP polling and registrar zone file processing.
What it would actually take: Requires an ingest pipeline processing Verisign's daily .com zone files (over 100M+ domains) using high-performance parsing in Go or Rust. The hard part is managing rate-limited RDAP/WHOIS servers across distributed proxies to monitor drops accurately without getting IP-banned, combined with full-text/regex indexing (e.g., ClickHouse or PostgreSQL Trigram) for instant wildcard querying.
