Every type of domain tool, and the question it answers.

The map: tool types and their jobs

Every domain tool answers a narrow question. Pick tools by the question you need answered, not by brand. The table lists each type, the question it answers, common examples, and the Toyroom tool that covers it where one exists.

Research tools: where the demand is

Registered-domain search is the core research tool. It searches every name found in zone files, the lists registries publish of the names they hold. Search a word to see how many names contain it, or an exact name to see which extensions already hold it. A name taken in hundreds of extensions has a lot of people who want it. Read more in How many extensions is a domain taken in?

Zone CounterSearch 350M+ registered names by keyword, prefix, or suffix.

Extension statistics answer which extensions are worth buying into. Size, weekly registrations, growth, the share of names that also have the .com, and parking rates tell you whether an extension has real users or mostly speculators. As of September 2026, .com holds about 168 million of the 393 million names in Toyroom’s index.

TLD ExplorerStatistics for every extension with 1,000 or more names.

Registration trends and certificate monitors show what is new. Daily registration lists reveal which words are heating up. Certificate Transparency logs show new websites, including names in country-code extensions that do not publish zone files.

Due diligence: RDAP, DNS, and history

Before you buy, confirm the basics. RDAP, the successor to WHOIS, gives the registrar, creation and expiry dates, and status flags. DNS tells you whether the name resolves, handles email, or points at a parking or sales page. Both are free.

RDAP LookupRegistration date, age, registrar, and status for a whole list.

Two checks no lookup tool does for you: search trademark databases such as the USPTO and WIPO for the name, and look at the name’s old websites in the Wayback Machine. A trademark conflict or a spam history can wipe out a name’s value.

Valuation: appraisals and comparable sales

Automated appraisals estimate a price from features of the name: extension, length, words, how many extensions hold it, and market signals. Most are trained on reported sales. They are useful for screening thousands of names and for a first range on one name. They disagree with each other often, so check more than one.

Comparable sales are the second half of any valuation. A sales database lists what similar names sold for, when, and where. Match on extension, length, and type of word, and prefer recent sales. The full method is in How to value a domain name.

Acquisition: expiring names and marketplaces

Most investors buy in two places: expiring-domain auctions, where names that owners did not renew are sold, and marketplaces, where other investors list names at a fixed price. Expiring lists are large, so the useful tools are the ones that filter and rank. See How to find expiring domains worth buying.

Portfolio tools: running what you own

Portfolio tools split into two groups. Operational tools hold, renew, and sell names: registrar dashboards, portfolio managers, and lander services. Analysis tools tell you what the portfolio contains and what it is worth, which drives renewal and pricing decisions. The full system is in How to manage a domain portfolio.

APIs and automation

Once a workflow repeats, move it to an API. Toyroom’s developer API offers appraisal, categorization, camelCase splitting, zone counts, RDAP, and DNS over REST, plus an MCP server so AI assistants can call the same tools. Bulk jobs take up to 1 million names.
