I am a big fan because it's an open source photo sharing program. It's easy to upload, search, see and find all photos, which a big help in the real estate industry. I work with countless houses and finding them can sometimes be a big hassle. Lychee makes it super easy for me and everyone to get to what they need!

I installed Lychee on my Raspberry Pi (old model B) and the result is amazing ! The install was really easy with Nginx and performances excellent. You can then create your own server or host to not share your picture with already existing Cloud companies. Another good point is the design and UX of the interface. It's all in simplicity but with a modern dark theme. Last point, the plugin system that can help you to have additional functionalities. One that i use is the plugin that help to synchronise your pictures from an external host (in my case Dropbox). I take a picture from my phone that is synchronized on Dropbox and then my self hosted Lychee get it automatically.

Lychee is a free photo-management tool, which runs on your server or web-space. That's usually the best option, as hosting your images in a remote service leaves you at the expense of the owner of that service. Lychee fills that gap in the market beautifully, using a snappy and beautiful interface and very little resources. I find really interesting the concept of "smart albums", that organize your pictures in special albums (apart from your regular albums) depending on specific criteria, like the amount the stars received. There's another really good thing about Lychee, and that's how easy it is to install it. It uses PHP, so you don't need a high-end server to run it, so that's great.
