- Zyte: A new analysis from Zyte reveals that nearly half of the top websites require JavaScript execution to render their content, making them inaccessible to simple HTTP scrapers.
Why it matters
This finding underscores the growing barrier that JavaScript-dependent rendering poses for web scraping and data extraction. Practitioners relying on plain HTTP requests will miss a significant portion of web content, pushing the need for headless browsers or rendering services. It also highlights the shift in web architecture that complicates extraction workflows and increases infrastructure costs.
