Flustro
Flustro was born out of the need to share links or thoughts with friends and people I know on a private level, without having to write to them directly. Instead of bombarding each person at the next time i meet them, with content that I may have forgotten, it made more sense to let people decide for themselves when they wanted to receive and view that content.
Also, the goal was to have sovereignty over one’s own data, i.e. be self-hosted. Furthermore, it shouldn’t be necessary for recipients to log in somewhere to receive the content and it should be available via RSS reader.
The project is still quite young but by the minimalist concept already feature complete.
I released it on Gitlab and you can try a demo here
