I think that DevOps might be the better subreddit for this question. I don’t know of any Alerta alternatives.

Mostly for improving my administration skills. I am a Linux Systems Administrator and gaining experience with Docker will almost certainly help me in the long term. The self hosted and Nginx proxy, has also contributed.

But in my day to day life? PiHole has reduced the number of ads I see, I believe. And I am migrating the sites that I watch for work from Follow That Page, to self hosted Change Detection. Storing recipes in Mealie might be helpful. Oh, I also want to set up that bookmarking tool that saves pages for me.
