Use Speedlify2 to Continuously Measure Website Performance

Inspired by a lack of budget for a web performance monitoring tool, the original Speedlify project (Speedlify Classic) was shipped to continuously measure site performance. It ran Lighthouse against a predetermined list of sites and ranked their performance against each other. Over time, I started to add a few more things to Speedlify.

Over six years, it’s pretty natural that some…
