(It looks like I've been monopolizing this channel lately, sorry 🙂 ) We created an interesting, although still beta, Umbraco Site Checker at https://www.dot-see.com/check-your-umbraco-sites-health/ - not intrusive - checks your public page only, and gives you useful insights from what it can find about your site - only if it is an Umbraco site. It cannot access your back office or provide detailed information on what's going on with your add-ons, but you'll be surprised how many things it can find just from the front-end. Yes, we store your query (emal + url), but only to be able to check against repeated / automated requests as well as send you the report. We will never use it to send you additional emails (unless you check the optional checkbox). Give it a spin - and let me know how it goes. Thanks!
