NitroPack the best with very good support
Since I am very concerned that the Core Web Vitals are optimal for my websites, I have found NitroPack to be the best tool for improving speed scores. Since I was having problems with the setup of my websites, I contacted support. Delia from NitroPack did an excellent job of giving me the support I needed to get NitroPack set up correctly on all three websites. The results are fantastic, 99 - 100 even for mobile, and that already in the free version. I can only recommend NitroPack. After spending many years improving my three websites to be google compliant in speed, NitroPack has finally given me the ability to improve the Core Web Vitals for mobile to 99-100. This was previously difficult or impossible to achieve with the various caching plugins, despite the best website performance. Therefore, from my own experience, I can only recommend NitroPack to improve the performance of a website in the best possible way.
