Compare a name across extensions
Use Quick check for one name, and understand multi-extension results, eligibility, and cached evidence.
Use Quick check for one completed name
Select the extensions you want, then enter a name in Quick check's Compare extensions mode. Exact domain mode checks just the full name you enter, such as yourname.co.uk. The quick check leaves your wordlists and saved bulk scan intact and starts only when you press Check name.
Compare evidence, not guarantees
Taken, Unknown, Unsupported, and Not found in RDAP mean different things. A missing registration record is a lead; the registrar confirms eligibility, price, and whether it can sell the name. Cached rows show their original check time. A stopped row marked Not checked has no new result.
Check the extension's requirements
.app and .dev websites require HTTPS. Some country extensions have presence or regional eligibility rules, linked beside the picker. Confirm first-year and renewal costs before purchasing, especially for .inc. Browser access can also vary by registry and network.
For a small wildcard comparison, the sample below checks Alphabet across .app and .dev: 26 words × 2 extensions = 52 checks. It prepares the bulk form; it does not start a quick check or a scan automatically.
Prepare a 52-check sample
Pattern: * · Extensions: .app, .dev · Built-in list: Alphabet (26 words).
Opening the sample only fills the form. Review it and press Start scan to send registry requests. Your existing lists and saved findings are kept. The sample link contains only its pattern, extensions, and built-in list ID.
