Quick Start

from browser_use_lite import BrowserUseCloud

client = BrowserUseCloud(api_key="bu-...")  # or set BROWSER_USE_API_KEY env var

# Create a cloud browser session
session = client.sessions.create()
print(session.cdp_url)    # wss://...
print(session.session_id)

# Use with Playwright
from playwright.sync_api import sync_playwright
with sync_playwright() as pw:
    browser = pw.chromium.connect_over_cdp(session.cdp_url)
    page = browser.contexts[0].new_page()
    page.goto("https://example.com")

# Cleanup
client.sessions.delete(session.session_id)

# Or use context manager for auto-cleanup
with client.sessions.create() as session:
    ...  # session auto-deleted on exit

Session CRUD

session = client.sessions.create()       # POST /browsers
info    = client.sessions.get(session_id) # GET  /browsers/{id}
items   = client.sessions.list()          # GET  /browsers
client.sessions.delete(session_id)        # PATCH /browsers/{id} (stop)
