Parallel Extraction

Run multiple extraction tasks concurrently with asyncio.gather or Promise.all.

When you need to extract the same kind of data from multiple URLs, run tasks in parallel. Each task gets its own browser session — they do not interfere with each other.

Python

import asyncio
from browser_use_sdk import AsyncBrowserUse
from pydantic import BaseModel

class Site(BaseModel):
    name: str
    description: str
    top_headline: str

urls = [
    "https://news.ycombinator.com",
    "https://reddit.com/r/technology",
    "https://techcrunch.com",
]

async def extract(client, url):
    return await client.run(
        f"Get the name of the site, a one-sentence description, and the top headline from {url}",
        output_schema=Site,
    )

async def main():
    client = AsyncBrowserUse()
    results = await asyncio.gather(*[extract(client, url) for url in urls])
    for r in results:
        print(r.output)

asyncio.run(main())

Each run() call automatically creates its own session. There is no need to manage sessions manually for independent tasks.
