Domain Checker

Check domain availability, status, and structure in a simple browser-based validator.

Domain Checker

How it works

siteIndex processes input directly in your browser whenever possible, which keeps the tool fast and keeps your data private.

For URL requests, the app validates the address and only allows public HTTP/HTTPS targets before running the check.
