Pushing performance monitoring further with actionable insights

Introducing performance recommendations

Up until today Calibre has used Google’s Pagespeed Insights API to give performance recommendations to our customers. The ease of deployment, reliability and cost at scale were big winning factors for us — except for when a site used basic or form based authentication.

Simply put, we had no ability to make recommendations for authenticated sites without developing our own analysis suite.

Introducing Performance Recommendations

Our first cut plays homage to Pagespeed, which we were in desperate need of replacing. We’re huge fans of the work that our friends at Google are doing on Lighthouse too, and even more excited by the possibilities that true offline-capable web applications bring.

Calibre Recommendations will score your site (out of 100), and provide actionable insights for how you might improve performance from where you’re at. We rolled Performance Recommendations to our reporting code last week, so if you log into Calibre right now, you’ll have recommendations ready and waiting for you 🎉

Recommendations in action

Recommendations are formed around uncachable resources, poorly set headers and large resources. Now that we’ve started on this engine, we’re excited at the further analysis we can bring you in the future. 👀

We have so much more that we’re excited to share with you as we continue our mission to make the web fast for everyone. 🌍🌏🌎

Calibre is for teams who want to monitor, alert and improve the performance and user-experience of websites and applications. Sign up today!
