How it works
- Add the domains you want to monitor - one per line, paste in bulk if you have a list.
- We check WHOIS automatically. Daily on the Basic plan, every hour on Pro.
- When the status changes - expiring soon, in redemption, dropped, or freshly available - you get an email. Pro adds Telegram alerts so you can react in seconds.

Frequently asked questions
How often does Domain Monitor check WHOIS?
Basic accounts get a daily WHOIS check per domain. Pro accounts are checked every hour, with extra checks as a domain nears expiration.
Which TLDs are supported?
Common TLDs work reliably (.com, .net, .org, .co, .io, .info, .co.uk and many more). Some niche extensions have limited WHOIS access - try the Basic plan to check.
Will I get notified when a domain becomes available?
Yes. The moment WHOIS confirms a watched domain has dropped, you receive an email. Pro accounts also get a Telegram alert.
Can I cancel anytime?
Yes. Cancel from your account whenever you want. You keep Pro access until the end of the billing period you've already paid for.
What happens to my domains if I cancel?
Your full list is kept. After cancellation we keep the oldest 3 active on the Basic plan and store the rest. If you resubscribe later, every domain comes back automatically.
