Backup your photos for free using this self-hosted image gallery
It's better than I expected

I've been using Google Photos to back up my pictures for close to a decade now. For the most part, I've had a seamless experience doing so, since the app automatically backs up photos shot on my phone in the background. Whenever I need to access my gallery, I can either use the app or fire up Google Photos on the web. However, there are two issues with a service like Google Photos. One -- you need to pay for cloud storage beyond a certain capacity, and two, your data is uploaded to remote servers, so there's always some sort of risk involved. Owing to this, I started looking for alternatives that tackled both these issues.
