DomainDiscovery is a free domain name search and research toolkit. Check availability across 1,600+ TLDs, generate brandable names with AI, run bulk checks, and find buyers for domains you already own. No account, no signup.

Why I built it

Finding a good domain usually means bouncing between a registrar's search box, a name generator, a WHOIS site and a spreadsheet. I wanted one fast, private place to do the whole job, from first idea to a shortlist you can take to any registrar.

What you can do

Find domains

- Instant domain search across 1,600+ extensions: .com, .ai, .io, .co, .dev, country codes and new gTLDs

- AI domain name generator that turns a keyword into short, brandable ideas, checked for availability

- Keyword domain finder and geo domain generator (niche + city or country) for local SEO and multi-location brands

- 30 industry pages with ready-made name ideas: restaurants, law firms, real estate, SaaS, fitness and more

Check in bulk

- Bulk domain search for up to 1,000 names in one pass

- See free, taken and premium results side by side, then export to CSV

Research before you buy

- WHOIS / RDAP lookup: registrar, creation and expiry dates, nameservers, status

- Domain age and expiry checker

- DNS lookup for A, AAAA, MX, NS, TXT, CNAME, SOA and CAA records

- Domain value estimator (a rough estimate from length, extension and keywords, not a professional appraisal)

- Registrar price comparison by TLD: registration, renewal and transfer prices, so you can see the renewal cost before you commit

- A TLD encyclopedia with a page for every extension: rules, registry and prices

Find buyers (for domain investors)

- Domain leads: see which businesses already use your name on other extensions, so you know who to contact

- Guides on end-user outreach and pricing a domain for sale

Learn

- 235 free guides on choosing a name, .com vs .io vs .ai, trademarks, valuation, expired domains, DNS, transfers, auctions and registrar reviews

- The site and 165 of the guides are available in 12 languages: English, Chinese, Spanish, German, French, Portuguese, Japanese, Hindi, Arabic, Russian, Bengali and Urdu

Private by design

- No account needed for any core tool

- Saved shortlists stay in your browser

- DomainDiscovery is not a registrar. When you're ready to buy, you register at the registrar of your choice

Built for

- Founders and indie hackers naming a new product

- Agencies and freelancers picking domains for clients

- Local businesses looking for a city or regional domain

- Domain investors researching names and finding end-user buyers

A note on accuracy

Availability results are live checks, but domains can be registered at any moment, so always re-check at the registrar before you pay. Prices come from public registrar pricing and can change with promotions.

Also for AI assistants

Every page has a clean Markdown version, plus llms.txt, so ChatGPT, Claude, Perplexity and other assistants can read and cite the tools accurately.
