Why it matters
Founders, indie hackers, and developers waste hours manually checking domain availability across multiple registrar portals with aggressive upselling. This tool generates brandable domain permutations instantly and runs 100% client-side with zero tracking.
When to use it
Use when brainstorming names for a new SaaS product, open-source project, startup, mobile app, or personal portfolio without alerting domain front-runners or squatters.
Common questions
How does the client-side DNS availability check work?
The tool uses privacy-preserving DNS-over-HTTPS (DoH) queries directly from your browser to check for active A, AAAA, and NS records. If a domain returns NXDOMAIN (non-existent domain) and no nameservers, it is very likely available for registration.
Are my searched keywords tracked or front-run?
No. Unlike some commercial registrars that log search history and reserve trending names, all generator algorithms execute entirely in your local browser sandbox. No queries are transmitted to central analytics or private tracking servers.
What makes a domain score high on the Brandability index?
The scoring model evaluates character length (under 10 chars is premium), syllable cadence, vowel-to-consonant ratios, avoidance of hyphens and ambiguous homoglyphs (like 0 vs O or 1 vs l), and TLD recognition.
Which registrar offers the lowest renewal fees?
Wholesale at-cost registrars like Cloudflare Registrar and Porkbun generally provide standard TLD renewals at zero markup without inflated introductory discounts followed by 300% price hikes.
