- Updated `run_auth_command` to provide detailed authentication status updates and debug information during the authentication process. - Introduced a new `UpdateAgentSessionEvent` class to facilitate session updates. - Enhanced `CloudSync` to allow all events during the authentication flow and to show direct links for authenticated users. - Improved error handling and user messaging for authentication failures. - Updated documentation to clarify cloud sync settings and authentication instructions.

## Overview
|
|
|
|
Browser Use has a native integration with [Laminar](https://lmnr.ai) - open-source platform for tracing, evals and labeling of AI agents.
|
|
Read more about Laminar in the [Laminar docs](https://docs.lmnr.ai).
|
|
|
|
## Setup
|
|
|
|
|
|
|
|
Register on [Laminar Cloud](https://lmnr.ai) and get the key from your project settings.
|
|
Set the `LMNR_PROJECT_API_KEY` environment variable.
|
|
```bash
|
|
pip install 'lmnr[all]'
|
|
export LMNR_PROJECT_API_KEY=<your-project-api-key>
|
|
```
|
|
|
|
## Usage
|
|
|
|
Then, you simply initialize the Laminar at the top of your project and both Browser Use and session recordings will be automatically traced.
|
|
|
|
```python {5-8}
|
|
from browser_use import Agent, ChatOpenAI
|
|
import asyncio
|
|
|
|
from lmnr import Laminar, Instruments
|
|
# this line auto-instruments Browser Use and any browser you use (local or remote)
|
|
Laminar.initialize(project_api_key="...", disabled_instruments={Instruments.BROWSER_USE})
|
|
|
|
async def main():
|
|
agent = Agent(
|
|
task="open google, search Laminar AI",
|
|
llm=ChatOpenAI(model="gpt-4.1-mini"),
|
|
)
|
|
await agent.run()
|
|
|
|
asyncio.run(main())
|
|
```
|
|
|
|
## Viewing Traces
|
|
|
|
You can view traces in the Laminar UI by going to the traces tab in your project.
|
|
When you select a trace, you can see both the browser session recording and the agent execution steps.
|
|
|
|
Timeline of the browser session is synced with the agent execution steps, timeline highlights indicate the agent's current step synced with the browser session.
|
|
In the trace view, you can also see the agent's current step, the tool it's using, and the tool's input and output. Tools are highlighted in the timeline with a yellow color.

## Browser Use Cloud Authentication
|
|
|
|
Browser Use can sync your agent runs to the cloud for easy viewing and sharing. Authentication is required to protect your data.
|
|
|
|
### Quick Setup
|
|
|
|
```bash
|
|
# Authenticate once to enable cloud sync for all future runs
|
|
browser-use auth
|
|
# Or if using module directly:
|
|
python -m browser_use.cli auth
|
|
```
|
|
|
|
**Note**: Cloud sync is enabled by default. If you've disabled it, you can re-enable with `export BROWSER_USE_CLOUD_SYNC=true`.
|
|
|
|
### Manual Authentication
|
|
|
|
```python
|
|
# Authenticate from code after task completion
|
|
from browser_use import Agent
|
|
|
|
agent = Agent(task="your task")
|
|
await agent.run()
|
|
|
|
# Later, authenticate for future runs
|
|
await agent.authenticate_cloud_sync()
|
|
```
|
|
|
|
### Reset Authentication
|
|
|
|
```bash
|
|
# Force re-authentication with a different account
|
|
rm ~/.config/browseruse/cloud_auth.json
|
|
browser-use auth
|
|
```
|
|
|
|
**Note**: Authentication uses OAuth Device Flow - you must complete the auth process while the command is running. Links expire when the polling stops.
