5 Playwright Mistakes That Are Silently Breaking Your Scrapers

Five common Playwright mistakes that silently degrade web scrapers at scale, with practical fixes for each. The mistakes covered are: using time.sleep() instead of Playwright's built-in auto-waiting, downloading unnecessary assets like images and fonts instead of blocking them with route.abort(), launching a new browser instance per URL instead of reusing browser contexts, relying on fragile deeply-nested CSS selectors instead of semantic locators, and repeating UI login flows instead of saving and reusing authentication state via storage_state JSON files.
