nodriver is a Python library for browser automation that communicates directly with the browser via the Chrome DevTools Protocol (CDP), without relying on Selenium or chromedriver. It is the successor to undetected-chromedriver, created by the same author, and is designed from the ground up to be undetectable by anti-bot systems.

Key advantages over traditional browser automation:

No chromedriver dependency Communicates directly with Chrome/Chromium via CDP websocket, eliminating the most common detection vector (chromedriver fingerprint).
Undetectable by default Does not set the navigator.webdriver flag, does not inject automation-related JavaScript, and avoids CDP detection patterns that anti-bot systems look for.
Fast and lightweight Without the Selenium/WebDriver protocol overhead, nodriver is significantly faster at launching browsers and executing commands.
Async-first Built entirely on Python's asyncio, enabling efficient concurrent browser automation.
Simple API Clean, Pythonic API that is easier to use than raw CDP or Selenium.

nodriver is particularly useful for scraping websites protected by advanced anti-bot systems like Cloudflare, DataDome, or PerimeterX, where standard Selenium or Playwright setups get detected and blocked.

Example Use

```python import nodriver as uc import asyncio

async def main(): # Launch browser - undetected by default browser = await uc.start()

# Open a new tab and navigate
tab = await browser.get("https://example.com")

# Wait for an element and interact with it
search_box = await tab.find("input[name='q']")
await search_box.send_keys("web scraping")

# Click a button
button = await tab.find("button[type='submit']")
await button.click()

# Wait for navigation and extract content
await tab.wait_for("div.results")
results = await tab.query_selector_all("div.result")

for result in results:
    title = await result.query_selector("h3")
    print(await title.get_text())

# Take a screenshot
await tab.save_screenshot("results.png")

browser.stop()

asyncio.run(main()) ```
