Try using Playwright or Puppeteer, both of which allow you to emulate mobile devices completely. They also support different network profiles, which is handy if you need to mimic mobile network speeds.

I’d say it depends on the scale. Python is efficient for prototyping and small-to-medium projects, but for high-frequency scraping, GoLang’s concurrency might be worth looking into. It can be much faster for handling parallel requests.

GraphQL can be easier to scrape because you can specify exactly what data you want.

I also use Playwright for dynamic sites because it’s faster and more reliable than Selenium in some cases. It handles multi-page navigation seamlessly and supports both headless and headed modes.

If your app requires flexibility and you don’t want the overhead of a large framework, Flask is the way to go; otherwise, Django can save time with pre-built components.
