Browser Bridge extension.

Last updated July 10, 2026

Jaz Browser Bridge is the companion Chrome extension for Jaz. It connects Jaz browser workers to the Chrome profile running on your own computer, so your local Jaz app can use the browser you are already signed into.

1. What it does

The extension opens a local WebSocket bridge to Jaz at ws://127.0.0.1:5299/v1/browser/extension. When you ask Jaz to work in the browser, the extension can navigate tabs, inspect page state, click, type, fill forms, scroll, wait for page changes, and capture screenshots for the task you requested.

The extension is not a standalone cloud service. It is useful only with the Jaz desktop app or a Jaz backend you control.

2. Requirements

Google Chrome with the Jaz Browser Bridge extension installed.
The Jaz desktop app or local Jaz backend running on your computer.
Auto-connect enabled in the extension side panel, or a manual connection to your Jaz bridge URL.

3. Data handling

Browser content is processed only when you use a Jaz browser feature. Depending on the action, the extension may read the current URL, page title, visible text, semantic page elements, screenshots, tab metadata, and form fields needed to complete your request.

By default this data is sent to the Jaz backend running on your own computer. If you configure Jaz to use a remote backend or an AI provider, the relevant browser context is sent according to your Jaz settings and the providers you choose. Jaz does not sell this data or use it for advertising.

More detail is available in the Jaz Privacy Policy.

4. Permissions

The extension asks for browser permissions so Jaz can operate the browser at your direction:

tabs, activeTab, webNavigation. Find, create, navigate, and observe browser tabs used by Jaz tasks.
scripting and host access. Inject the packaged content script into pages so Jaz can read page state and interact with controls across sites you ask it to use.
storage. Save the bridge URL, auto-connect setting, session-tab mappings, and local action history in Chrome.
sidePanel. Show connection status, bridge settings, and recent browser actions.
alarms. Wake the extension periodically so it can reconnect to the local Jaz bridge.

5. Setup

Install and run Jaz on your computer.
Install Jaz Browser Bridge from Chrome.
Open the extension side panel and keep the default local bridge URL unless you use a remote backend.
Confirm the status changes to connected, then run a browser task from Jaz.
