Automatic Lighthouse Score Tracking

4/11/2025

I’ve started performing monthly maintenance on quite a few websites that I wasn’t involved with during the design and construction phase. There is quite a variety of websites, and they range from pretty recent to ancient, but they all could use help with regards to speed, optimization, and general cleanup and refinement.

On most of these sites, I’ve started to collect Lighthouse scores, and I’ve started to work on some of the recommended fixes and updates. Its’ a good feeling to make the improvements, but I’ve been wanting to track those changes, to see the improvements in a more quantifiable way.

I started a new app that I’m hoping will become a robust tool to help me continually improve the library of websites that I manage. To check for errors and issues, and to offer insights into things that can be improved. one of the first tasks has been to (mostly) automate those Lighthouse scores and save them, along with the date so I have a record of how the various updates improve the score, I’ve been tracking a couple of websites, and plot to scores over time, so now for any page on a website that I’m tracking, I can easily see a graph of Lighthouse scores over time, and hopefully be able to see a visual representation of improvement.

There is of course much more to do with the app, but it’s a nice, and pretty useful first step.
