Why self-host instead of Sync.com?
- Own your data — it lives on a server you control, with backups you decide on.
- Predictable cost — a small VPS often replaces per-seat pricing for a whole team or family.
- No lock-in — open-source licenses let you keep running the software even if a vendor disappears.
The trade-off: you are responsible for updates, backups and security. Pick an app marked Active (a commit in the last 90 days) and with Docker support for the easiest ride.
