Usage

from o_browser import BrowserClient, RemoteBrowser

# Local headless browser
async with BrowserClient() as browser:
    await browser.goto("https://example.com")
    text = await browser.get_text()

# Persistent Chrome profile (cookies survive between runs)
async with BrowserClient(profile_path="~/.config/browser/linkedin") as browser:
    await browser.goto("https://linkedin.com")

# With recording (HAR + video)
async with BrowserClient(record=True) as browser:
    await browser.goto("https://example.com")

# Interactive (opens browser window, waits for user to close)
async with BrowserClient(interactive=True) as browser:
    await browser.wait_closed()

# Connect to remote Chrome (e.g. o-browser-full)
# RemoteBrowser auto-creates a session via POST /api/sessions if none active.
async with RemoteBrowser("http://host:8080", workflow="my-app") as browser:
    await browser.goto("https://example.com")

# Disable auto-session if you manage sessions yourself
async with RemoteBrowser("http://host:8080", auto_session=False) as browser:
    ...

Features

• Headless and headful modes

• Proxy support
• Cookie management
• CDP connection to existing Chrome instances
• Anti-detection via Patchright

Site adapters (plugins)

Site-specific scrapers are separate distributions, not bundled in core. Each registers in the o_browser.sites entry-point group and is discovered at runtime:

from o_browser import load_site, available_sites

available_sites()                       # -> ['vivatech', ...] (installed adapters)
VivaTechClient = load_site("vivatech")   # pip install o-browser-vivatech
