FreshRSS is a self-hosted RSS and Atom feed aggregator.
In my experience, it has been great for staying updated on news and managing a significant portion of my social media, including video sharing platforms like PeerTube, Odysee etc :-)

I installed it on a container (LXC) on my Proxmox home server. I only use it at home, I have not made it remotely accessible
