Parsehub is dead easy to use, you can build website scrapper just by clicking on the data that you want. It then exports the data in Excel or JSON format. It has many handy specs such as mechanical IP rotation, permitting scraping behind login walls, going via tabs and dropdowns, getting data from maps and tables, and much more. Further, it has a sweet free tier, permitting users to scrape up to two-hundred pages of data in just forty minutes.
Diffbot is different from the most scrapping page tools (find more about tools for web scraping here)out there in that it uses a PC vision (instead of html parsing) to identify match information on a page. This means that even if the HTML structure of a page replaces, your web scrapper will not break as long as the page looks the same visually. This is an amazing spec for long running mission critical website scraping jobs.
