Track available short domains and hourly .com market movements.
Available Short Domains
Browse 540,000+ unregistered 1 to 4-character names open to register across 47 TLDs (.ai, .io, .app, .dev, .co, and more). Filter by pronounceable patterns (CVCV, VCVC), exclude specific letters, and sort by Cross-TLD demand.
Premium Domains Monitor
Hourly change radar across 4M+ premium .com domains (all 1 to 4-character .coms and keyword .coms). Track registrar transfers, expirations, new registrations, and nameserver changes across a rolling 7-day window.
Search Is a Snapshot. Monitoring Is a Stream.
A standard search shows where the domain market stands when you run a query. Domain monitoring checks high-value segments on a schedule and surfaces changes as they are detected: when a short name in one of 47 extensions opens up for registration, when a 4-letter .com points its nameservers to an aftermarket platform, or when an overlooked short .com slips into expiration.
Curated Market Radars vs. Custom Email Alerts
Use the two monitors above to browse curated market segments. To watch your own targets instead, a free account includes Keyword Monitor, which emails you when new registrations, new hostnames, expirations, deletions, or new for-sale listings match your keyword, and Domain Monitor, which emails you when a domain you follow changes. Click Add email alert after a keyword search on New Domains, Expired Domains, or Deleted Domains, or on a domain in Domain WHOIS.
Frequently Asked Questions
What domain monitoring tools and alerts does DomainKits offer?
DomainKits provides two market monitors alongside email alerts you set up in your account:
- Available Short Domains: Lists 540,000+ unregistered 1 to 4-character domains across 47 extensions (.ai, .io, .co, .app, .dev, .tech, .xyz, and 40 more) that are open to register.
- Premium Domains Monitor: Scans 4M+ premium .com domains (all 1 to 4-character .coms and keyword .coms) every hour, listing registrar transfers, expirations, new registrations, and nameserver changes over a rolling 7-day window.
- Keyword and Domain Email Alerts: With a free account, Keyword Monitor emails you when newly registered, expired, deleted, or newly listed for-sale domains (or new hostnames) match your keyword, and Domain Monitor emails you when a domain you follow changes.
How do investors and brand teams spot early opportunities in monitoring streams?
Raw change streams are noisy without a filter. Four baseline signals help isolate actionable domains:
- High Cross-TLD + Pronounceable Pattern (Available Short Domains): Among 540,000+ open short names, filtering for Pure Alpha plus CVCV (consonant-vowel-consonant-vowel) and sorting by Most TLDs surfaces 4-letter names in .ai, .io, or .dev that read like real words and are already registered across many other extensions.
- Nameserver Moves to Aftermarket Platforms (Premium Domains Monitor): Filtering the 4M+ .com list by Nameserver Change shows when a dormant short or keyword .com points to an aftermarket platform's nameservers (such as Dan, Afternic, or Sedo), which often signals a new for-sale listing.
- Custody and Launch Signals (Domain Transfer and Hosting DNS): A registrar transfer on a 3-letter or 4-letter .com can follow a private sale or a portfolio consolidation, while a move from parking nameservers to hosting DNS (such as Cloudflare or AWS Route 53) often marks a domain preparing to launch.
- Overlooked Short .com Renewals (Domain Expired): Even high-value .coms occasionally miss a renewal. Filtering the hourly .com change list by Domain Expired and the 1-3 or 4 length filter shows when a short .com enters expiration, so you can track it in Expired Domains.
How often is the monitoring data refreshed?
Each monitor runs on its own cycle:
- Premium Domains Monitor: All 4M+ monitored .com domains are scanned every hour, and detected transfers, expirations, registrations, and nameserver changes are added to the rolling 7-day list.
- Available Short Domains: Availability across the 47 tracked extensions is refreshed regularly. Short names can be registered between refreshes, so clicking Register confirms current availability and pricing at the registrar.
- Email Alerts: Keyword and domain monitors check on a schedule set by your plan, and paid plans can check more often (see pricing).
