Playwright란 무엇인가요?
Playwright is Microsoft's open-source browser automation framework that provides a single API to control Chromium, Firefox, and WebKit browsers. It supports headless and headed modes, auto-waiting, and network interception, making it a leading choice for testing and web scraping.
What is Playwright?
Playwright is an open-source browser automation library developed by Microsoft, released in 2020. It provides a unified API for automating Chromium (Chrome, Edge), Firefox, and WebKit (Safari) browsers — all from a single codebase. Playwright was created by the same team that originally built Puppeteer at Google, and it represents the next evolution of browser automation with first-class support for modern web application patterns.
Unlike older automation tools that bolt onto browsers through external drivers, Playwright communicates directly with browser engines using their native protocols. This direct connection enables features that are difficult or impossible with driver-based approaches: intercepting network requests, emulating mobile devices, handling multiple browser contexts in a single process, and auto-waiting for elements to become actionable before interacting with them.
Key Features
Playwright's architecture delivers several advantages over competing frameworks:

Playwright for Web Scraping
While Playwright was designed primarily for testing, it has become a leading web scraping tool because:
왜 중요한가요
Playwright represents the current state of the art in browser automation. Its reliability, speed, and cross-browser support make it the foundation for both automated testing pipelines and production web scraping systems that need to handle modern, JavaScript-heavy websites.
Autonoly는 어떻게 해결하나요
Autonoly is built on Playwright for its browser automation engine. When the AI agent navigates websites, fills forms, clicks buttons, and extracts data, it uses Playwright under the hood. This gives Autonoly reliable automation across all major browsers, with built-in handling for dynamic content, iframes, and modern web application patterns — all controlled by natural language instructions.

자주 묻는 질문
Is Playwright better than Selenium?
For modern web applications, Playwright offers significant advantages: faster execution, built-in auto-waiting, native Shadow DOM support, and direct browser communication without external drivers. Selenium has a larger ecosystem and broader language support, and it remains the standard for organizations with existing Selenium infrastructure. For new projects, Playwright is generally the recommended choice due to its modern architecture and developer experience.
Can Playwright be used for web scraping?
Yes, Playwright is widely used for web scraping, especially for JavaScript-heavy websites that require browser rendering. Its auto-waiting prevents timing-related failures, network interception speeds up scraping by blocking unnecessary resources, and browser context isolation enables parallel scraping sessions. While Playwright was designed for testing, its capabilities translate directly to reliable, scalable web scraping.
What is the difference between Playwright and Puppeteer?
Both were created by the same team, but Playwright is the more capable successor. Playwright supports Chromium, Firefox, and WebKit; Puppeteer supports only Chromium. Playwright has built-in auto-waiting and browser context isolation; Puppeteer requires manual implementation. Playwright offers official bindings for Python, Java, and .NET in addition to JavaScript; Puppeteer is JavaScript-only.
