Syncthing is an open-source continuous file synchronization program that syncs files between two or more computers over a peer-to-peer network. It is written in Go, encrypts data in transit, and runs on all common platforms with a web GUI and native wrappers.
Use cases
- sync files between my laptop and desktop without a cloud provider
- replace Dropbox with a self-hosted sync tool
- keep a folder mirrored across multiple devices automatically
- sync photos from my Android phone to my home server
- continuously back up files between machines over my LAN
- share a folder with a friend without uploading to third-party servers
When to choose
- you want private, encrypted, peer-to-peer sync without cloud storage
- you need cross-platform continuous synchronization including Android
- you prefer self-hosted software with no vendor lock-in
When to avoid
- you need real-time collaborative editing or versioned cloud sharing links
- you want managed cloud backup with offsite retention
- you need a simple one-way backup tool rather than two-way sync
