Bottom line: Vacato is domain monitoring software that polls public RDAP on a schedule and alerts you when a target name looks available. You bring the list; we check and ping — you register at any registrar. It is not drop-catching and not a registrar.
Most “domain monitoring” products either browse public drop catalogs or attempt registry creates at delete. Vacato is different: you bring the list, we check availability on a timer, and we alert you when a name looks open.

FAQ
What is domain monitoring software?
Software that repeatedly checks whether domain names are registered and alerts you when status changes. Vacato polls public RDAP/WHOIS on a schedule — every 5 minutes on Free, every minute on Pro.
Is Vacato drop-catching software?
No. Vacato is monitoring and alerts. Drop-catch platforms attempt the registry create. Use Vacato for the watchlist; add a catcher only on names you will contest.
Does Vacato have an API?
Yes on Pro and Business. REST and MCP endpoints for watchlist management and availability checks. See /docs/api.
How is Vacato different from DomainTools or registrar monitoring?
DomainTools and registrar tools often track portfolio changes (DNS, expiry fields) on names you own. Vacato focuses on availability alerts for names you want to acquire — RDAP polling on your private watchlist.
What does domain monitoring software cost?
Vacato Free covers 10 domains with 5-minute checks. Pro is $7/month for 100 domains with 1-minute checks. Business is $19/month for 500 domains. See /pricing.
