Namecheckup alternative and comparison
Namecheckup checks a handle across major social networks and dozens of domain extensions at once, and it knows each platform's naming rules. Here is how it works and how it compares with a broader checker.

What is Namecheckup?
Namecheckup covers major networks such as Instagram, TikTok, X, YouTube, GitHub and Bluesky, plus 40+ domain extensions. Results are marked available, taken or invalid, where invalid means the handle breaks that platform's rules on length or characters.
The site states that it is free, needs no account and does not collect personal data when you search. It also links to WHOIS and domain marketplaces for taken domains, publishes a table of per-platform username rules, and has checkers for game names such as Minecraft and Roblox.
How to use Namecheckup
- Enter the handle on namecheckup.com.
- Filter between social networks and domain extensions.
- Look for "invalid" marks, which mean the name breaks that platform's rules.
- Confirm on the platform itself before you build a brand on a result.
