Playwright

Overview

Playwright is Microsoft’s modern browser automation framework that provides a single API to automate Chromium, Firefox, and WebKit. It’s the gold standard for end-to-end testing and web scraping.

Key Features

• Cross-Browser: Single API for all major browsers
• Auto-Waiting: Automatically waits for elements to be ready
• Network Control: Intercept, modify, and mock network requests
• Mobile Emulation: Test mobile web with device emulation
• Code Generator: Record interactions to generate test code

Why It Matters

Playwright has become the de facto standard for browser automation. Its reliability, cross-browser support, and excellent developer tools make it the foundation for many AI browser tools (Browser Use and Stagehand both build on Playwright).
