What Syncthing actually does
Syncthing is an open source file synchronisation tool that operates on a peer-to-peer model. It replicates directories directly between your local machines or servers without routing data through a central third-party cloud service. The software is written in Go and distributed via container images and binary packages.
Best fit: It is well-suited for users who want to maintain complete ownership of their data while keeping multiple devices synchronised across a local network or the internet.
Worth knowing: You will need to manage your own firewall rules and ensure that both devices can establish a direct network connection or route through a relay, which can complicate setup behind strict corporate NATs.
Deployment notes
Deployments typically require persistent storage volumes to retain synchronised files and configuration data across container restarts. You may also want to configure a reverse proxy to secure the administrative web interface with TLS.
