DomainTools is regarding to get more expensive for some users

Firm is eliminating old plans in favor of fresh “Personal” accounts.

DomainTools began as a firm catering to the domain name industry, but has shifted to the enterprise security market in recent years.

This summer, as part of that process, DomainTools is eliminating a number of grandfathered plans and pushing fresh accounts into a Personal plan. For many people, this will mean substantially higher prices.

The fresh Personal plans are $99 a month or $995 a year. DomainTools is offering a 30% off coupon code (upgradenow) to help with the transition.

Personal plans include fresh products previously available only to larger clients, counting bulk parsed whois and reverse whois research mode, along with reverse IP. Personal membership also includes 5 Domain Notes per month (which individually cost $49 each).

Personal memberships have limits that some people might exceed. For example, Personal accounts can only monitor 1,000 domains per month. If you use domain monitors to track your portfolio for domain hijacking, this won’t be possible under the fresh plans for people with more than 1,000 domains.

Competitors to DomainTools have come on the scene in recent years. DomainIQ is aimed squarely at this market and has plans starting at $24.95 per month. Whoisology offers some free access to data and has extended plans starting at $30 per month.

Each service has different features and limits. Frankly, there’s no “best” choice for everyone; it really depends on what you’re using the services for.

Account migrations at DomainTools will begin June 25, but clients can upgrade early.
