What does the software or service do well? They have some ready-to-use templates for some common websites like Airbnb, TripAdvisor. You can just input the website link and click start, then the task will run to get your required data. It saves a lot of time compared to building the task step-by-step. In addition, Octoparse offers cloud service. With cloud service, I can run the crawlers even when I turned off may lap, and the speed is also very fast.
