Page Speed Insights vs Web Developer Tools

[easymodemedia]

Hi everyone,

Would someone be able to tell me the difference between Page Speed Insights vs Web Developer Tools.

I've tested the same site on both multiple times, and the two tools never line up in terms of LCP, TTI and CLS. Web Dev Tools rates the site much better than PSI, despite using Lighthouse to run the test.

Kind of confused what to target if the results are slightly different so I think I need to understand the differences in the reports a bit better.

Thanks for any help!
