Compare competitor websites in an exportable table
With Smart Design Inspector you save a card for every website you visit (SEO, headings, schema, fonts, colors and speed) and compare several of them in a table you can export to CSV or Markdown.
Comparing 2 websites is free forever

Why comparing by hand doesn’t work
The problemYou open your website and three competitors’. You check each title with one extension, the headings with another and the fonts with a third. You copy every value into a spreadsheet. The next day, half of it is gone and you have to open them all again.
Tools that compare websites stick to one thing: speed, links or traffic. None of them puts design and SEO in the same table.

How it works
4 steps- 01
Open the website and click Save card. The extension saves the title, description, headings, structured data, fonts, palette, Core Web Vitals and a screenshot.
- 02
Repeat for each competitor.
- 03
Open Compare and pick the cards. The differences are highlighted.
- 04 Pro
Export the table to CSV (for your spreadsheet) or to Markdown (for your report, or to hand it to an AI).
03

What it’s used for
3 usesClient proposal
Their website against Google’s top three for their service, in one table.
Before you design
Which fonts and colors the industry uses, and what the top-ranking site does.
SEO audit
Who has schema, who has no H1 and who loads slowest.
06
What it doesn’t compare
LimitsNot traffic, keywords or backlinks. Those need third-party data like Semrush’s or Similarweb’s. The comparison only uses what can be read on the page itself.
Can I compare my website with my competitors’ for free?
Yes. The free version saves 3 cards and compares 2 websites on screen. To export the table or compare more websites, you need Pro.
Where are the cards stored?
In your browser. They aren’t uploaded to any server and you don’t need an account.
Can I compare pages from the same website?
Yes. Each URL is a card, so you can compare the home page with a service page, or two versions of the same page.
Does it work with websites behind a login?
Yes, as long as you can see them in your browser. The extension reads the page exactly as you see it.
What format does it export to?
CSV, which opens in Excel or Google Sheets, and Markdown, for reports or to paste into a chat with an AI.
Is the speed data Google’s?
It’s from your own visit, measured live. Real-user data (CrUX) will come in a later version.
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. The code is ready to be brought to Firefox and Safari without a rewrite. While it’s in development, things may change.
