TabBridge

Transfer your tab groups between Chrome, Brave, and Edge — in seconds.

---

The Problem

You've got 40 tabs organized into perfect groups. Now you need them in another browser.

Chrome doesn't let you transfer tab groups. Neither does Brave. Or Edge. You're stuck copying URLs one by one.

The Solution

TabBridge exports all your tab groups — names, colors, tabs — into a single JSON file. Open any Chromium browser, import the file, and your groups are back. Exactly how you left them.

No accounts. No cloud. No backend. Just a JSON file.

• Export — Captures all tab groups with titles, colors, and URLs
• Import — Recreates tab groups with correct names and colors
• Download — Save as a .json file
• Copy — Copy JSON to clipboard
• File upload — Import from a saved JSON file
• Cross-browser — Works on Chrome, Brave, Edge, and any Chromium browser
• Offline — Everything runs locally, nothing leaves your machine

JSON Format

TabBridge uses a simple, human-readable JSON format:

{
  "version": "1.0",
  "exportedAt": "2025-05-07T10:15:00.000Z",
  "browser": "Chrome",
  "groups": [
    {
      "title": "Research",
      "color": "blue",
      "collapsed": false,
      "tabs": [
        {
          "title": "OpenAI",
          "url": "https://openai.com"
        },
        {
          "title": "Anthropic",
          "url": "https://anthropic.com"
        }
      ]
    }
  ]
}

You can edit this file by hand if you want. It's just JSON.
