flexinfer-browser-kit

Production-ready browser automation library for Python, built on Playwright. Features advanced stealth evasion techniques and robust session management.

Features

• Stealth Mode: Pre-configured evasion scripts to bypass bot detection (custom args, JS injection).
• Session Management: persistent context storage with file locking for safe concurrency.
• Resilience: Configurable timeouts, proxy support, and automatic retries.

Installation

pip install flexinfer-browser-kit
# For stealth features
pip install "flexinfer-browser-kit[stealth]"

Usage

Basic Scraping

from browser_kit import BrowserManager

manager = BrowserManager(headless=True)

with manager.new_context() as context:
    page = context.new_page()
    page.goto("https://network-tools.com/request")
    print(page.title())

Stealth Mode

from browser_kit import BrowserManager

# Uses custom args and evasion scripts by default
manager = BrowserManager(
    headless=True,
    stealth=True,  # Enable evasion
    user_agent="Mozilla/5.0..."
)

with manager.new_context() as context:
    page = context.new_page()
    page.goto("https://bot-detection-check.com")

Persistent Sessions

manager = BrowserManager(storage_dir="./sessions")

# Automatically loads/saves cookies to ./sessions/my-session.json
context = manager.new_context(session_id="my-session")
