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.

Requestium is a Python library that merges the power of Requests, Selenium, and Parsel into a single integrated tool for automatizing web actions.

The library was created for writing web automation scripts that are written using mostly Requests but that are able to seamlessly switch to Selenium for the JavaScript heavy parts of the website, while maintaining the session.

Requestium adds independent improvements to both Requests and Selenium, and every new feature is lazily evaluated, so its useful even if writing scripts that use only Requests or Selenium.

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()) ```

```python from requestium import Session, Keys session = Session(webdriver_path='./chromedriver', browser='chrome-headless', default_timeout=15) # then session object can be used like requests and parsel: title = session.get('http://samplesite.com').xpath('//title/text()').extract_first(default='Default Title') # other advance functions like POST requests and proxy settings are also available: s.post('http://www.samplesite.com/sample', data={'field1': 'data1'}) s.proxies.update({'http': 'http://10.11.4.254:3128', 'https': 'https://10.11.4.252:3128'}) # session can also be used like selenium as it exposes all selenium functions. # like typing keys: s.driver.find_element_by_xpath("//input[@class='user_name']").send_keys('James Bond', Keys.ENTER) ```
