If your Playwright scraper has stopped working because of anti-bot systems used by websites, you’re not alone. This is a common issue in web scraping. As soon as you update your scraper to bypass the anti-bot measures, the companies behind these systems quickly upgrade their systems to detect and block your scraper again. It's a continuous arms race against anti-bot systems.
In the realm of web automation and testing, managing cookies effectively is crucial for simulating authentic user interactions and maintaining complex application states. Playwright, a powerful browser automation framework, offers robust capabilities for handling cookies in Python-based scripts. This comprehensive guide delves into the methods and best practices for setting cookies in Playwright with Python, providing developers and QA engineers with the tools to create sophisticated, reliable automation solutions.
Cookies play a vital role in web applications, storing user preferences, session information, and authentication tokens. Properly managing these small pieces of data can significantly enhance the fidelity of automated tests and web scraping operations. Playwright's cookie management features allow for precise control over browser behavior, enabling developers to replicate complex user scenarios and navigate through multi-step processes seamlessly.
This article will explore various methods for setting cookies in Playwright, from basic usage of the add_cookies() method to advanced techniques for handling dynamic responses and managing cookies across multiple domains. We'll also delve into best practices and advanced cookie management strategies, including automated consent handling, leveraging browser contexts for session management, and implementing cross-domain cookie sharing.
By mastering these techniques, developers can create more robust and efficient automation scripts, capable of handling a wide range of web application scenarios. Whether you're building automated test suites, web scrapers, or complex browser-based tools, understanding how to effectively manage cookies in Playwright is essential for achieving reliable and scalable results.
Throughout this guide, we'll provide code samples and detailed explanations, ensuring that readers can easily implement these strategies in their own projects. From basic cookie setting to advanced persistence techniques, this comprehensive overview will equip you with the knowledge needed to harness the full power of Playwright's cookie management capabilities in Python.

In the ever-evolving landscape of web automation and testing, two tools have consistently stood out: Playwright and Puppeteer. As of 2024, both have matured significantly, offering robust features for developers and testers alike. Both tools, developed by teams at Microsoft and Google respectively, offer robust solutions for automating browser tasks, but they cater to slightly different needs and preferences.
In the rapidly evolving landscape of web automation and testing, two open-source frameworks have emerged as leading tools: Playwright and Selenium. Both frameworks offer unique features and capabilities, making the choice between them a nuanced decision that depends on specific project requirements and team expertise.
Web scraping is the process of extracting necessary data from external websites. It’s a valuable skill that helps you gather large amounts of data from the internet for various purposes. However, it can be daunting if you don’t need what tools to use.
With the increasing use of the internet worldwide, it is being implemented in all aspects of our daily lives. So using it efficiently and effectively becomes crucial and could be the difference between competitors and businesses. This is where the concept of Web Automation comes in. Today I shall teach you one of the most debated topics of web automation, Puppeteer vs. Selenium.
Let's begin!
This article will expose how to block specific resources (HTTP requests, CSS, video, images) from loading in Playwright. Playwright is Puppeteer's successor with the ability to control Chromium, Firefox, and Webkit. So I'd call it the second one of the most widely used web scraping and automation tools with headless browser support.
Java is one of the most popular and high demanded programming languages nowadays. It allows creating highly-scalable and reliable services as well as multi-threaded data extraction solutions. Let's check out the main concepts of web scraping with Java and review the most popular libraries to setup your data extraction flow.
In this article, we'll take a look at how to submit forms using Playwright. This knowledge might be beneficial while scraping the web, as it allows to get the information from the target web page, which requires providing parameters before.
