Can someone explain the exact scrapers definition? How do they work? or What’s the real scrapers defi

Not a dumb question! The scrapers definition is pretty much what you said—automated tools that fetch web data.

But legality? *Big* depends. Some sites explicitly allow it (Twitter’s API), others sue (hiQ vs LinkedIn). Always check terms of service.

How they work? Way more than copy-paste! They parse HTML, handle JS, even mimic humans (headless browsers like Puppeteer).

Try Apify if you want a cloud-based scraper.
