Dexi.io – how to improve performance

Intro

Some may argue that extracting 3 records per minute is not fast enough for an automated scraper (see my last post on Dexi multi-threaded jobs). However, you should realize that Dexi extractor robots behave like a full-blown modern browser and fetch all the resources that crawled pages load (CSS, JS, fonts, etc.).
In terms of performance, an extractor robot might not be as fast as a pure HTTP scraping script, but its advantage is the ability to extract data from dynamic websites which require running JavaScript code in order to generate a user-facing content. It will also be harder for anti-bot mechanisms to detect and block it.

Turn any interactive website into an API with ParseHub

parsehubAnyone should be able to pull data from the web and access it in the format they want. If a website does not have an API available, scraping is one of the only options to get the data you need. But figuring out how to scrape data in the complicated HTML is a pain.

ParseHub is a scraping tool that is designed to work on websites with JavaScript and Ajax; it is similar to web scraping tools such as Import.io and Kimono Labs.

scraping-software-services-sum-up

Since we have already reviewed classic web harvesting software, we want to sum up some other scraping services and crawlers, scrape plugins and other scrape related tools.

Web scraping is a sphere that can be applied to a vast variety of fields, and in turn it can require other technologies to be involved. SEO needs scrape. Proxying is one of the methods which can help you to stay masked while doing much web data extraction. Crawling is another sub-technology indispensable in scrape for unordered information sources.
