FAQ
Is the extension free?
Yes, completely free. No account, no subscription, no hidden fees.
Does it work on Edge and Brave?
Yes! Any Chromium-based browser supports this extension — Chrome, Edge, Brave, Opera, Vivaldi.
Does it send my data anywhere?
No. All analysis happens locally in your browser. No data is sent to any server. The extension only communicates with serpux.com if you explicitly use the 'Full Audit' link.
Can it analyze login-protected pages?
Yes! Unlike online tools, the extension runs inside your browser, so it can analyze any page you have access to — including admin panels, dashboards, and staging sites.
How is this different from the online SEO audit?
The extension is instant (0.3s) and works on any page including private ones. The online audit does deeper checks like security headers, broken links, robots.txt, and sitemap validation.
