Features
A clean public checker with an admin-first backbone.
Fast discovery
Search without the TLD
Enter just WhoisCheckr or the full WhoisCheckr.com and the checker will test the enabled extensions so you can see quickly what is still available.
Context
Combined exact reports
Each exact domain opens into a report page with live DNS data, availability context and stored internal search history for that domain.
Built to grow into a real lookup product.
This version already routes supported TLDs to official RDAP sources, while the admin panel keeps provider mapping, persistence and future expansion under control.
