Hello fellow enthusiasts!
While browsing the internet, I came across this website.
They have created very simple applications with minimal security that can be self-hosted.
As of today, they have built 8 applications.
Kindly, go through the site and give them a try.
Thanks for posting. This is new for me as well. All of them are open source under GPL 3.0 license. 
Oh nice share !! Thanks. Just in time when I was looking for something for asset management. Well not complex like snipe-it. Dumb Assets looks just fine for the job. Also checking out Homebox for the same.
As a DIY enthusiast, I am always searching where did I put that 100ohm resistor or where are the heat shrink sleeves. Hoping for this to alleviate that problem.
