A site scraper written in Node.js, using mongoDB to store scraped information. Requests HTTP headers using asynchronous Node.js (very fast, compared to similar scraping methods such as requesting via cURL), and uses mongoDB for data storage. Interested in monitoring thousands of sites over a period of days to months for changes in the back-end? This is your tool. I cannot guarantee all scraped information is 100% legitimate, as HTTP headers can be spoofed, however, if a rough understanding of potential clients is what you are interested in doing, this is your tool.
