Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
OnionShare
- Requires Tor; recipients need Tor Browser, creating friction for non-technical users
- Shares are typically ephemeral and one-time by default; not suited for persistent storage
- No folder sync, versioning, or long-term file organisation
- Transfer speeds are slow due to Tor network routing
Syncthing
- Pure peer-to-peer sync: no cloud copy, so files only exist where a device is online (no always-available server unless you run one)
- No web file browser, sharing links, or per-file access control like Dropbox
- No built-in versioning UI beyond simple file versioning options
- Not designed for multi-user team sharing; it's device-to-device for one owner
Bottom line
Both are a similar lift to self-host; choose Syncthing for the larger community and ecosystem. Syncthing has seen more recent development. Open each guide below for deploy steps and the full feature gap.
