Often, the information we need gets trapped in a site, and we cannot scrape or crawl it properly. While some sites make efforts to present data in clean and structured formats, the others cannot provide any web crawling or data scraping facility. That is why we will need to access the best web crawlers, miners, and scrapers. Here we have discussed the top five tools in this regard.
Webhose.io enables us to get the real-time data from online resources and sites. The best part is that this program mines and crawls the sites conveniently and presents data in clean and well-organized format. It also enables us to scrape data based on their keywords, phrases, languages, and nature. The final results can be obtained in the form of XML, RSS and JSON files. Though this program is free of cost, you may access its premium version if you want to use Webhose.io for commercial purposes. The paid plan will enable you to send multiple HTTP requests to the main server, making it easy for you to scrape and crawl the sites.
