I run a paid Chrome extension that I'm still working on: https://www.checkbot.io/

> Checkbot is a Chrome extension that tests 100s of pages at a time to find critical SEO, speed and security problems before your users do. Test unlimited sites as often as you want including local development sites to stop critical issues going live.

Glad I didn't rely on the Chrome Web Store payment system they deprecated a few months ago. :) Felt predictable they were going to throw in the towel with it since it was lacking obvious features and the support forums always had complaints about it breaking.
