Hi HN! I'm Ben, the solo founder of Calibre Analytics: <a href="https://calibreapp.com" rel="nofollow">https://calibreapp.com</a>. Calibre monitors websites and applications in a clean-room testing environment from all over the world. Up until January Calibre has been an "inbetween other things" / evenings / holidays kind of project. (Only, oops—I did that for four years.). Last year I knuckled down to get into the position where I could work on it full time.<p>I've spent the last 8 weeks working on "Test profiles" (The launch post is here: <a href="https://medium.com/get-calibre/announcing-test-profiles-and-budgets-2-0-84667a4e4749" rel="nofollow">https://medium.com/get-calibre/announcing-test-profiles-and-...</a>) — It allows you to emulate hardware devices (cpu speed, user-agents and screen dimensions), as well as limit the bandwidth (latency, download and upload speeds), and set cookies (you could use this to log into your app, test a staff-shipped feature, or maybe turn off advertising and see the performance impact.) I think I've finally got the basis of a really powerful tool, and I'm keen to share it with… everyone! I do everything myself, so if you've any questions, I'm here to answer them!

I totally mistook this for Calibre[0], the open-source e-book app.<p>The site looks really good. This is a very impressive product for an "in-between other things"/evenings/holidays kind of project. My only issue is that the animation of the application window coming up can sometimes be laggy.<p>0: <a href="https://calibre-ebook.com/" rel="nofollow">https://calibre-ebook.com/</a>
Calibre seems to be one of the only website performance testing tools that is keeping up with the new "user centric" website performance stuff coming out of Google aka Lighthouse.<p>I quite enjoyed watching this brain storm session with Paul Irish around Lighthouse and new metrics for measuring website performance in a meaningful way.<p>Edit: Forgot to include the link -> <a href="https://www.youtube.com/watch?v=IxXGMesq_8s" rel="nofollow">https://www.youtube.com/watch?v=IxXGMesq_8s</a>
Test profiles is an especially interesting idea, something that I don't believe other tools in this space (Gomez/Compuware APN, ThousandEyes) have quite yet. Other than test profiles, what sets Calibre apart?
I'd suggest a name change as calibre is already well established open source e-book management software. From my results you are the 6th result on google searching for "calibre".
We've been using calibre app on Vecteezy and its helped us keep track (and improve) our site performance. Its a great tool and continues to improve!
