## Overview

Check Domain is built for the moment between having a name idea and paying a registrar. Instead of a single yes/no answer, it fans a search out across popular extensions — .com, .net, .org, .io, .ai and others — and returns availability for each, so you can see whether your brand reads well on more than one suffix before committing. Availability comes from each registry's RDAP service rather than a DNS guess, which removes the false confidence that a quick DNS lookup can create.

When a name is already registered, the tool surfaces the public record: registrar, key registration and expiry dates, nameservers, and the registry source. Alongside that record it places the two prices that actually matter to buyers — the discounted first-year registration offer and the ongoing renewal cost — so the cheapest headline price is not mistaken for the cheapest long-term choice.

There is no sign-up, no saved search history and no tracking cookies in this version; queries are processed on demand. That makes it a lightweight utility for founders naming a product, developers auditing a domain before a purchase, or portfolio owners checking a buy across several extensions. The tool is transparent that availability is only authoritative at the registrar's checkout, so it positions itself as research rather than a guarantee.

## Pricing & Plans

Check Domain is free to use with no account required. Its own pages state that the basic lookup does not use accounts, a search database or tracking cookies, and that searches are processed on demand. There is no paid plan documented on the site.

## Key Features & Capabilities

- **Multi-extension availability in one search:** Enter a brand word or full domain and see how it fares across .com, .net, .org, .io, .ai and other extensions at the same time.
- **Registry-backed RDAP results:** Availability is checked against each registry's RDAP service rather than inferred from DNS records, reducing misleading 'available' answers.
- **Public WHOIS and RDAP detail:** For registered names, inspect registrar, registration and expiry dates, nameservers and the registry source behind the record.
- **Registration vs renewal price comparison:** First-year offers sit next to renewal costs so you can judge the real long-term price of a name before buying.
- **No account, no search history:** Searches run on demand with no sign-up and no stored query history or tracking cookies in this version.

## Primary Use Cases

- **Check a product name across extensions (Founder / brand namer):** Test a shortlist of brand ideas across several TLDs at once to see which combinations are realistically available before falling in love with one.
- **Audit an existing domain (Developer / site owner):** Pull the WHOIS record to confirm a domain's registrar, key dates and nameservers before a migration, transfer or purchase.
- **Compare acquisition economics (Domain investor):** Weigh a cheap first-year registration against the renewal price to estimate the true holding cost of a candidate name.
- **Quick pre-purchase sanity check (Casual buyer):** Run a no-account search to confirm a name is free or taken, then finish the authoritative check at the registrar's checkout.

## Strengths

- Powers availability checks with registry RDAP data instead of DNS guesses
- Shows registration and renewal prices side by side, avoiding cheap-first-year traps
- Covers many extensions in a single search
- No account, no saved history and no tracking cookies

## Limitations

- Does not sell domains itself — final availability is only confirmed at the registrar
- Coverage of price data varies by registrar and extension
- Focused on lookup and comparison rather than management or DNS hosting

## Frequently Asked Questions

### How do I check whether a domain is available?
Type a brand word or a full domain such as northstar.com, pick the extensions you care about, and review the results. Each one is labelled available, registered, for sale or needing confirmation.

### Can I check many domain extensions at once?
Yes. Check Domain queries supported registry services across your selected extensions and returns results as each registry responds, letting you compare suffixes side by side.
