Steel is a developer platform that provides cloud browser infrastructure for web agents. By integrating with Notte, you can use Steel’s browser infrastructure to run reliable browser agents using Chrome DevTools Protocol (CDP).

​
Adding Steel to existing Notte implementations

​
1. Install Notte and Steel SDK

uv pip install notte-sdk
uv pip install steel

​
2. Initialize Notte and Steel

Import the libraries and create a cloud browser session:
steel_init.py

STEEL_API_KEY = os.getenv("STEEL_API_KEY")

# Initialize clients
steel = Steel(steel_api_key=STEEL_API_KEY)
client = NotteClient()

# Create a browser session on Steel

​
3. Connect Notte to Steel’s CDP endpoint

Use Steel’s CDP URL to create a Notte session:
steel_connect.py

# Connect Notte to Steel's browser via CDP
with client.Session(cdp_url=steel_session.websocket_url) as session:
    # Create an agent with a task
    agent = client.Agent(session=session, max_steps=10)

    # Run your automation task
    result = agent.run(task="extract pricing plans from https://www.notte.cc")

​
Complete example script

Here’s a complete, runnable script that demonstrates the full integration:
steel_complete.py

STEEL_API_KEY = os.getenv("STEEL_API_KEY")

steel = Steel(steel_api_key=STEEL_API_KEY)
client = NotteClient()

# Create a browser session on Steel
steel_session = steel.sessions.create()

try:
    # Connect Notte to Steel's browser via CDP
    with client.Session(cdp_url=steel_session.websocket_url) as session:
        agent = client.Agent(session=session, max_steps=10)

        result = agent.run(task="extract pricing plans from https://www.notte.cc")

        print(f"Task completed: {result.answer}")

except Exception as e:
    print(f"Error during automation: {e}")

finally:
    steel.sessions.release(steel_session.id)
    print("Steel session released")
Steel’s SDK may evolve. Refer to Steel’s documentation for the most up-to-date API details.

Benefits of using Steel with Notte

  • No local browser management: Run agents without installing or maintaining browsers locally
  • Cloud infrastructure: Leverage Steel’s managed browser infrastructure
  • Scalability: Launch multiple browser sessions in parallel for concurrent tasks
  • Session control: Programmatic control over browser lifecycle
