This guide covers how they work internally, when to choose one over a regular browser, and which frameworks are worth your time.
TL;DR: Scrapy-Playwright lets you render JavaScript-heavy pages directly inside Scrapy spiders by controlling real Chromium, Firefox, or WebKit browsers through Playwright. This tutorial walks you through installation, configuration, page interactions, AJAX interception, anti-detection, and a production-ready project structure so you can scrape dynamic sites without leaving the Scrapy ecosystem.
