Syncthing Cloud - Setup Guide

First, navigate to the Syncthing Cloud website and sign up for a new account or log in if you already have one.

If you haven't done so already, you'll need to add your billing information before you're able to add a subscription.

After your billing information has been setup, you'll need to pick a plan to subscribe to. This will provision your dedicated Syncthing Cloud instance.

After subscribing, your new Syncthing Cloud instance will be assigned a randomly generated name and added to the Instances page. Click the name to pull up the instance detail page. This is where you'll find its device ID and manage its settings.

On your instance detail page, find the section for managing devices and go to add a new "Accepted Device". This will inform your to accept a connection from your local device.

Now, open the web interface for your local Syncthing running on your device.

The default address is typically http://127.0.0.1:8384/

In your local Syncthing UI, copy your device's ID (from "Actions" > "Show ID"). Then, switch back to the Syncthing Cloud browser tab and paste this ID into the "Device ID" field for the new "Accepted Device" you started in Step 4.

On the Syncthing Cloud page, after pasting the ID, give your local device a recognizable name (e.g., "My Desktop") and add the device.

Now, you need the ID of your cloud instance. Back on the Syncthing Cloud detail page for your instance, find and copy the Syncthing ID for the cloud instance itself.

Switch back to your local Syncthing UI. In the "Remote Devices" section, click the "Add Remote Device" button.

In the "Add Remote Device" dialog from the previous step, paste the Syncthing ID from your Syncthing Cloud instance (which you copied in Step 9) into the "Device ID" field.

In the same "Add Remote Device" dialog, go to the Advanced tab and check the "Untrusted" box. This setting enforces encryption for all folders shared with your Instance.

Syncthing Cloud will refuse any data that arrives unencrypted.

Go to the Sharing tab. Here, you can select the local folders you'd like to store on Syncthing Cloud. Click "Save" to add the device and begin syncing the selected folders.
