How should I format domain names?
Enter domains as example.com — without http://, https://, or subdomains like www. Just the bare domain and TLD.
Do I need an API key?
No. Domain Availability Checker works without any API keys or external accounts. Install and go.
Can I check many domains at once?
Yes. Enter your list of domains in a column and run the checker — it processes them all in one go.
