- 02
Besides design, you also check SEO.
- 03
You’d rather pay once than pay for a subscription.
Can I use both at the same time?
Yes. They are separate extensions.
Is Smart Design Inspector free?
Yes. Inspection, SEO and screenshots are free forever. The one-time-payment Pro adds the exportable comparison and design export.
How recent is the data in this comparison?
It’s from November 4, 2026. If something has changed, write to us and we’ll fix it.
Which browsers and operating systems does it work on?
Chrome, Edge, Brave, Arc, Opera and Vivaldi, on Windows, Mac and Linux, from version 1.0. It works the same everywhere because the browser runs the extension, not the operating system.
