I'm building FOSS alternatives from the ground up on top of IPFS. Not quite ready to use, but very promising (on desktop). Building the abstraction needed to do multi-device edits of the same IPNS key was the hardest part, but that work is done and usable for building any app. Might be another year before everything is stable enough to daily drive the storage implementation due to limited bandwidth to work on it, so I won't share here -- find me in the https://windowsappcommunity.com/discord if you'd like to see the work or contribute. If something happens to syncthing or people want a p2p alternative to the personal cloud, I'll be there!
