- Each has a real cost: Syncthing synchronisation, not backup: a deletion propagates to every device, and versioning must be configured deliberately; balenaEtcher fewer options than Rufus: no partition scheme or target system control
- They diverge on capability: Syncthing covers Peer-to-peer sync, balenaEtcher covers Cross-platform.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Syncthing
- Synchronisation, not backup: a deletion propagates to every device, and versioning must be configured deliberately
- Devices must be online simultaneously to sync, so an always-on machine is effectively required
- Initial setup involves exchanging device IDs and is less approachable than signing into a cloud service
- No web access to files, since there is no server holding them
balenaEtcher
- Fewer options than Rufus: no partition scheme or target system control
- An Electron application, so it is heavy for a tool that writes a file to a disk
- Earlier versions attracted criticism over analytics collection, which is worth checking in current builds
- Slower than lower-level tools because it validates every write

Answered from the vendors’ own pages
Syncthing: Is Syncthing free?
Yes, open source with no licence fee and no storage costs, because there is no server.
balenaEtcher: Is balenaEtcher free?
Yes, open source under the Apache 2.0 licence.
Syncthing: Is Syncthing a backup tool?
No. It synchronises, so deletions propagate. Use it alongside a real backup, not instead of one.
balenaEtcher: balenaEtcher or Rufus?
Etcher runs on all three platforms and is harder to misuse. Rufus is Windows only and gives far more control over partitioning and boot targets.
Syncthing: Do my files pass through anyone else’s servers?
No. Transfers are peer to peer and encrypted. Discovery and relay servers can help devices find each other, and relayed traffic remains encrypted end to end.
balenaEtcher: Does it verify the write?
Yes, it validates after flashing, which catches failing SD cards and USB sticks before you rely on them.
