Monitor Kit

Track domain market changes and availability

Unregistered AI Domains

Browse 3-4 letter .ai domains not yet registered. Filter by pattern (LLL, CVCV, VCVC, CCVV, etc.), find one you like, register it.

Premium Domains Monitor

Short .com and keyword .com domains that changed hands, dropped, or switched nameservers this week. Updated daily across 4M+ domains.

What Is Domain Monitoring?

Domain monitoring tracks changes in the domain market over time. Instead of searching for a keyword once, monitoring tools surface domains as they become available, change ownership, or update infrastructure. DomainKits monitors short .ai availability daily and premium .com changes within a rolling 7-day window.

Monitoring vs Search

Use domain search when you have a keyword and want to find matching domains right now. Use monitoring when you want to watch a market segment for new opportunities as they appear. Search is a snapshot. Monitoring is a stream.

Frequently Asked Questions

What domain monitoring tools does DomainKits offer?

DomainKits offers two monitoring tools: Unregistered AI Domains for browsing unregistered short .ai domains available for registration, and Premium Domains Monitor for tracking transfers, drops, new registrations, and nameserver updates across 4M+ premium .com domains.

How often is domain monitoring data updated?

The .ai availability list is refreshed daily. Premium Domains Monitor tracks a rolling 7-day window with updates typically processed within hours of detection.

What types of domain changes are tracked?

The Premium Domains Monitor tracks four categories: registrar transfers, expired or dropped domains, new registrations, and nameserver updates. Each change includes the domain name, change type, and detection date.

Do I need an account to use monitor tools?

Guest access is available with limited daily usage and basic filters. Creating a free account gives you higher rate limits and additional filter options. Premium and Platinum tiers unlock full filter access. See pricing for details on usage tiers.

How is monitoring different from domain search?

Domain search lets you find domains by keyword across active, new, aged, expired, and deleted databases. Monitor tools track ongoing changes and availability in specific segments. Search is for discovery by keyword. Monitoring is for tracking market movement over time.
