Not exactly my project, but I have been helping a friend of mine work on his pet project for the last couple of months: https://limeline.app/.

He currently makes no money from it and has no intent on making any anytime soon, hosting cost are pretty low and it was pretty much just created out of a need we both had: being able to aggregate all our sources for our morning technology watch.

In the end, with feedback from a couple of friends, he built a simple "no inbox" RSS aggregator with some nice extra features (account-less page management, sharing & forking of feeds, ...).

It is still in a pretty early stage, but I really like where this is going and feels like it deserve more visibility.
