Overview

Product summary

Review the store description, core capabilities, and common use cases.

Find your perfect domain name in milliseconds. Fast Domain Checker is a lightweight, privacy-first developer tool designed to verify domain availability across 100+ Top-Level Domains (TLDs) instantly.

Instead of relying on slow WHOIS lookups, our extension queries Google's Public DNS API to deliver lightning-fast results with ~90% accuracy. If it's not connected to a host, it shows as available!

🚀 KEY FEATURES:

• Instant Verification: Check multiple domains at once without loading screens.

• Smart TLD Management: Pin your favorite extensions (.com, .io, .ai, etc.) and hide the rest.

• Favorites & History: Star your best ideas and keep track of your recent searches. All data is saved strictly locally on your device.
