What are the best use cases for a headless browser in web automation? or How does a headless browser

Headless browsers are awesome but overkill for some sites. If the data’s loaded via XHR, you might not even need one—just inspect the network calls and scrape the API directly.

But for full-render pages, Playwright’s my pick. Way more reliable than Puppeteer, especially with shadow DOM stuff.

Speed’s always gonna suck compared to raw requests, but that’s the trade-off for JS rendering.
