About this extension
Check domain availability directly from your browser - no registrar APIs, no developer backend, no logging.

Why Secure Domain Search exists?

Finding the perfect domain can be stressful, and every query risks your ideas being exposed to registrars or third parties.

Secure Domain Search helps you check domain availability without using registrar APIs, reducing the risk of domain frontrunning. All lookups are performed directly from your browser using public DNS-over-HTTPS (DoH) and registry RDAP servers.

How it works?

DNS check (Cloudflare DoH) – If a DNS record exists, the domain is marked Unavailable.

Registry lookup (RDAP) – If no DNS is found, we query the domain’s registry directly.

Clear results – Domains are shown as Available, Registered, or Unknown.

Key features:

Privacy-first – No developer backend, no logging, queries stay in your browser.

Direct lookups – Uses public DNS-over-HTTPS and registry RDAP only.

Quick and reliable – Real-time availability results.
