FrameBuff learned from some excellent tools, and it runs happily beside all of them. It does most of what they do, on machines you own, with nothing to rent. Here is an honest side-by-side.

Polished file sharing, office documents and a big app store.
If you live in Nextcloud's apps, keep them. FrameBuff adds what a single server can't: every machine you own working as one, a drive encrypted on every disk, and a GPU you can lend.
Rock-solid peer-to-peer folder sync.
FrameBuff has sync of its own, and puts an encrypted drive, shared GPUs, family and apps on top of it. If Syncthing already keeps your folders in line, it can keep doing that.
Effortless private networking between devices.
FrameBuff connects its own machines without signing up anywhere, then does something with them once they're connected. It works fine on a network Tailscale already set up.
Smart-home automation with thousands of integrations.
Home Assistant runs your house. FrameBuff runs your computers and your data. They sit well side by side, even on the same machine.
Zero setup, and it works on every device.
Nothing beats them for convenience. FrameBuff asks for a little setup in return for storage that is yours: no monthly fee, no cap beyond your own disks, and nobody else holding the keys.
