Dexi.io is a powerful scraping suite. This cloud scraping service provides development, hosting and scheduling tools. The suite might be compared with Mozenda for making web scraping projects and runnig them in clouds for user convenience. Yet it includes the API, each scraper being a json definition similar to other services like import.io, kimono lab and parseHub.
OutWit Hub is a software providing simple data extraction without requiring any programming skills or advanced technical knowledge. What impressed me about Outwit Hub is its general approach to data gathering: harvest everything (links, text, images, etc.) and, then, let the user choose what is needed (sift by scrapers). The program is apt to browse over links on pages, so this feature works well if multiple chains web scraping is required.
