Is SEO Checker Tool - Get Free SEO Audit Analysis safe?

Clean risk

SEO Checker Tool opens an SEO audit page that includes the current tab URL encoded in the path.

When you click the extension button, it reads the current tab URL, base64-encodes it, and opens a new tab on the vendor's SEO checker page. The encoded URL is placed in the page path so the service can run an audit for the page you were viewing.
