Why it's listed

Written by the ValueIndex editor, from the verification pass of 2026-07-02.

Syncthing syncs files directly between your devices — no server, no account, no company in the middle. It's a single Go binary, TLS-encrypted peer-to-peer, governed by a foundation, and funded by donations. It has quietly done one job excellently for over a decade. We verified the no-central-server architecture and foundation governance.
