And this is exactly the reason I self host[0]. I am pretty sure it's not just me. I have seen r/selfhosted[1] skyrocket in it popularity over past year or two. The number of applications that you can self host are increasing daily. The only problem at the moment with self hosting seems to be the maintenance and setup but that also will be solved once many people start doing it. History repeats itself. Self hosting too will become mainstream once again
[0]: Why start self hosting https://rohanrd.xyz/posts/why-start-self-hosting/
You self-host things that are easily self-hostable. You wouldn’t self-host something like emails or error reporting.
I self-host e-mail. It's not always easy, but it's doable. It got easier over time with tools like docker-mailserver [1] and Mail-in-a-Box [2].
