Short answer, it was an overkill.
Jetpack is a plugin for WordPress by Automattic. It extends WordPress by offering extra features, like uptime monitor, that would email you if your site goes down, this is useful if you want to keep an eye on the uptime of your website, it also lets you automatically share your article once published.
They key feature that made me use Jetpack was the Photon CDN, which is good feature, but these days I prefer hosting all my content through my servers, giving me finer control.
It lets you integrate your website with WordPress.com, so you can use it for drafting articles, and analytics, but I no longer needed these features, I use Fathom for analytics and WordPress directly instead of WordPress.com
These are a few features that it offers, there is a lot more, but those are the key features that I can think of while authoring this article.
While Jetpack is great, it slowed down my server, the time to first byte was higher when I had it enabled, it also affected my server response time.
That’s my story for why I stopped using Jetpack.
