Distributed cloud storage?

Hello!

I recently had issues with my self-hosted instance of Nextcloud so I started looking for an alternative to it.

I would like something that could allow me to make a local network of shared files between devices I choose, if that makes any sense.

I stumbled upon Syncthing but it doesen't seem what I had in mind: I understand that it replicates folders between devices, but I am looking for a way to distribuite files between machines. Again, like Nextcloud but without a central server to rely to.

Do you know if something of that sort exists?

Or if you have any other solution?

Thank you.

P.S. I am posting it here because it seems like some sort of self-hosting, but maybe I will cross-post it to the decentralized comunity.
