I like it, because it's very lightweight and doesn't need a login or anything. I just used it to review my website and I found a few things that I would not have noticed otherwise. The webp converter also saved me a lot of time. Great work!

The tool is awesome! Gives you a quick overview of how much work a website is going to need in terms of SEO. Love how clicking a header takes you to the correct place on the website. The Image section makes thing easy to know what image has what alt text and what type of file format it is. Can't wait for the new AI feature that are rolling out!
