Requirements

• You must have the TabSync Local server installed either via:

npm install -g tabsync-cli
or 
pip install tabsync-cli

• Or, downlaod and use the electron based tabsync-desktop app from tabsync-desktop

Once started, it’ll show a local URL (e.g. http://192.168.x.x:port) and a QR code to open on other devices.

The extension connects automatically to that local server via http://localhost:port/ip.

Installation

• Clone or download this repository.
• Open Chrome → Extensions → Manage Extensions.
• Turn on Developer Mode (top right).
• Click Load unpacked and select the folder containing:
• Start your tabsync server from the terminal.
• Watch your desktop tabs appear instantly in the TabSync dashboard.

  Else use releases to download file

Troubleshooting

If you see:

TabSync Local: could not find server on port xxxx

Make sure:

• The local server (tabsync) is running (via CLI or the electron app).
• You opened the extension on the same machine or network as the server.
• The port (3210 by default) is not blocked by a firewall.
