It’s not as fully featured as Scrapy, but for most use cases, it’s the perfect balance between functionality and ease of use for Python programmers.

Use a Web Scraping API

If you are comfortable writing your web scraping code yourself, you still need to run it locally. This is fine for small operations, but as your data collection scales up, it willuse up precious bandwidth, potentiallyslowing down your network.

Using a web scrapingAPIcan offload some of the work to a remote server, which you can access via code. This method has several options, including fully-featured and professionally priced options likeDexi, and simply stripped back services likeScraperAPI.

Use IFTTT To Scrape a Website

Available for $3.50 on the Play Store, many view Tasker as IFTTT’s older sibling. It has a vast array of options for automation. These include custom web searches, alerts when data on selected websites changes, and the ability todownload content from Twitter.

While not a traditional web scraping method, automation apps can provide much of the same functionality as professional web scraping tools without needing to learn how to code or pay for an online data gathering service.
