Namechk alternative: check usernames and domains
Namechk is a long-running availability checker. You type a name and it shows which social sites and domain extensions look free. It is built for people choosing a brand or handle, and this page compares it with a broader alternative.

What is Namechk?
Namechk says it checks 36 domain name options and 100+ social media sites and online platforms. Results show as a grid: available names stand out and taken ones are dimmed.
Its focus is branding. Alongside the checker the site hosts guides on registering domains and picking a name, and it links out to registrars and WHOIS for domains that are taken.
How to use Namechk
- Type the name you want on namechk.com.
- Scan the domain list, then the social grid.
- Click through to a site to confirm before you rely on an "available" result, since some sites block automated checks.
