I built Raza Photos: a local, distributed photo library for your Apple devices if you are tired of clouds and subscriptions.

Not open-source for now, sorry, but I do consider open-sourcing the networking layer one day though. I am very proud of it and I am sure it would help many projects. It’s an amazing peer to peer system with many helpers like broadcasting, managing connections, discovering peers and so on. But the whole app needs a lot of stabilization so definitely not ready to be slapped publicly on GitHub.
Sorry, not trustworthy with private data. Good luck though.
