Works on any device
The tool runs in your browser, so there is nothing to install. It works on Windows, Mac, Android and iPhone. On mobile, the results table scrolls sideways so you can still see every column.
Safe and private
We never ask for your Ahrefs login or API key. Your list is sent securely over HTTPS, and check logs are deleted automatically after a few days.
Frequently asked questions
Do I need to install anything?
No. It works in any modern browser.
Is there a Chrome extension?
Not yet. Just bookmark this page for quick access.
Can I check subdomains?
Domains are checked at root level, because DR is a site-wide metric. blog.example.com is checked as example.com.
