Exploring web scraping vs. crawling: key roles, methods, tools, benefits, and challenges in data gathering.
Web scraping has become an essential tool for gathering information, and cloud web scrapers offer a practical entry point for those new to the field. Web scraping service providers often come with a “Self Service” option, allowing even those with basic technical know-how to build their own scrapers.
A self-service cloud web scraper is a good choice if you want to try web scraping and have the basic technical knowledge to build scrapers.
In this post, we will go through some of the popular cloud-based web scraping platforms and provide details about how they work and their pros and cons from information publicly available on their website.

- ScrapeHero Cloud
- Scrapy Cloud
- Cloud Scraper

The scraped data can be downloaded in CSV, JSON, and XML formats and delivered to your Dropbox. ScrapeHero Cloud lets you set up and schedule the web crawlers periodically to receive updated data from the website.
Every ScrapeHero Cloud plan has automatic IP rotation available to avoid getting blocked by the websites. ScrapeHero Cloud provides Email support to all free and lite plan customers and priority support to all customers with higher plans.

Cloud Scraper
Cloud scraper by Webscraper.io is another cloud web scraper platform where you can deploy scrapers built and tested using the free point-and-click Webscraper.io Chrome Extension.
