// FAQ

Frequently asked questions

How accurate are the availability checks?

We use RDAP (Registration Data Access Protocol) with DNS fallback. This catches most registered domains, though some obscure TLDs may show as "unknown."

Which TLDs are supported?

All major TLDs (.com, .net, .org, .io, .co, etc.) and most country-code TLDs. RDAP coverage varies by registry.

Is there an API limit?

We batch requests and add small delays to respect registrar rate limits. Large lists process smoothly without hitting blocks.

Do you store my domains?

No. All processing happens locally in your browser. We don't see, store, or transmit your domain lists anywhere.

Can I check premium domains?

The checker shows registration status, not pricing. Premium availability shows as "available" but may have higher registrar fees.

Why 50 checks per day on free?

To ensure the service stays fast for everyone. Power users who need more can upgrade to Pro for unlimited checks.
