The main difference of the screen scraper software by Mozenda from other scrapers is that it runs your scraping projects (Agents) in clouds. Firstly, you build a project locally using a Windows application and then you execute it on the server.
Screen Scraper is a classical scraping tool for all kinds of data scraping, extracting and packing. However, it takes time to properly master it.
Recently, a friend of my asked me for a simple free tool to detect new releases of the phpMyAdmin software. Since I recently did some research on website change tracking, I immediately recommended ChangeDetection.com. This service is free with basic logging in and primitive interface. The drawback of this service is that its pages load with 20th century delays, but for one-time page adding it’s okay.
