One Word Domains is a web-based database of 1,303,547 available, brandable one-word domain names, aimed at people looking for a name for a startup or other project. The site describes the collection as brandable domains at your fingertips, and it has been featured on Hacker News. Visitors can browse the list by top-level domain (TLD) instead of searching one name at a time.
The product is built around a curated word list rather than random strings. According to the site, it holds 27,625 English words tagged by category, such as adjectives, nouns and verbs, and checks which of them are available as domains across 94 TLDs. The newer DomainsGPT feature adds AI-generated name suggestions on top of the database.
The site explains its process in two visible steps. First, it curates a database of 27,625 brandable English words. The words carry labels like adjectives, adverbs, nouns, verbs and positive, and examples shown include fast, glow, genius, oasis and clarity. Some words also carry labels such as names, places, tech or spanish.
Second, it crawls various domain registrars to find the best prices for all 94 TLDs in the database, along with other statistics. For each TLD the table lists views, how many of the top 10 million sites use it, total sites, and the cheapest price found. Aftermarket, GoDaddy and Namecheap links also appear in the navigation.
The core feature is the database of 1,303,547 available one-word domains, which members can browse by TLD. The TLD table gives comparison data: for example, .com shows a cheapest price of $10.00 and 3.1M sites in the top 10M, while .ai shows $80.00 and 32.8K. Cheapest prices listed for .xyz and .fyi are $1.99 and $5.66.
DomainsGPT generates names with AI. The site also lists style-based options, including .com domains with a -gpt suffix, aimed at AI and GPT-related products, and .com domains with a use- prefix. A navigation link to an affiliate program is labeled new. The sources do not describe how DomainsGPT works in detail, so its output quality is untested here.
