What's installed on your Syncthing server?
- Syncthing 2 with its browser-based admin interface
- A password-protected interface: the login is yonetici, Turkish for admin
- Sync ports open: 22000/TCP and 22000/UDP
- A default sync folder named Sync
- HTTPS through Caddy, with the interface on an sslip.io address based on your IP
- Firewall with ports 22, 80, 443 and 22000 open
What size do you need for Syncthing?
Syncthing's documentation gives no RAM figure. CPU work happens during the first scan and when files change, and the docs say it's negligible once everything is in sync. As a rule of thumb, 1 GB is a good start, and 2 to 4 GB helps with lots of files or devices. Disk is what really matters: you need room for the total size of your synced folders, plus space for old copies if you turn on file versioning. Disk grows from your panel but can't shrink.
| Use | Size | Price | Choose |
|---|---|---|---|
| A few people | 1 GB RAM · 1 vCore · 25 GB NVMe | $2.58/mo | |
| Small team | 2 GB RAM · 1 vCore · 40 GB NVMe | $4.01/mo | |
| Company | 4 GB RAM · 2 vCore · 60 GB NVMe | $6.89/mo |
Who is it for?
- People whose devices are rarely online together but still need files in sync

- Location: Istanbul · IST-1.
Good to know
- Syncthing isn't a backup: deletions and changes spread to all your devices. File versioning is off by default and you turn it on per folder.
- You hold the rights and legal responsibility for the files you sync. Only move content you're allowed to use.
- The official team has no plans for iOS. The docs list community apps for phones instead: Syncthing-Fork on Android and Synctrain on iOS.
- Syncthing is free and open source (MPL-2.0), with no paid tier and no account.
- The panel keeps showing the install password, so store any new one yourself if you change it. Keeping Syncthing up to date is your job.
Syncthing questions and answers
How much RAM does Syncthing need?
There's no official figure. As a rule of thumb, 1 GB is a good start, and 2 to 4 GB helps with lots of files or devices. CPU use is negligible once everything is in sync. If it isn't enough, scale up from your panel. The server restarts once, and your data and IP stay the same.
How do I add a device to a Syncthing server?
In Syncthing on your computer, go to Actions, then Show ID, and copy your device ID. In the server's interface, paste it under Add Remote Device. Repeat the other way round, since two devices only connect once each has added the other. Then share your folders.
Can Syncthing replace a backup?
No. The official docs say it isn't a great backup application, because deletions and changes spread to all your devices. Your server is backed up every night, the last 7 days are kept, and that's included in the price, so you can recover a file you deleted by mistake from there.
Can I use Syncthing on my phone?
Yes, with community apps. The official docs list Syncthing-Fork for Android and Synctrain for iOS. The core team has no iOS plans because iOS restricts background work. These apps don't come from the Syncthing team.
Are my Syncthing files encrypted in transit?
Yes. Data sent over the network is always encrypted. If devices can't connect directly, volunteer-run relays may step in, and they can't see your data either. Port 22000 is open on the server, so your devices can reach it directly.
Why would Syncthing need a server?
Strictly speaking it doesn't, since it works with no central server. But devices only exchange data while online together. An always-on server holds the changes while your laptop is closed, and passes them along when the other device comes online.
