C vs. Racket vs. SQL vs. WebScraper.io Comparison Chart

Racket is a general-purpose, multi-paradigm programming language that serves as a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation, enabling developers to create new domain-specific and general-purpose languages. Racket's core language includes features such as macros, modules, lexical closures, tail calls, delimited continuations, parameters (fluid variables), software contracts, green threads, and OS threads. The language also comes with primitives, such as event spaces and custodians, which control resource management and enable the language to act like an operating system for loading and managing other programs. Further extensions to the language are created with the powerful macro system, which, together with the module system and custom parsers, can control all aspects of a language. Most language constructs in Racket are implemented as macros in the base language.

Making web data extraction easy and accessible for everyone. Our goal is to make web data extraction as simple as possible. Configure scraper by simply pointing and clicking on elements. No coding required. Web Scraper can extract data from sites with multiple levels of navigation. It can navigate a website on all levels. Websites today are built on top of JavaScript frameworks that make user interface easier to use but are less accessible to scrapers. WebScraper.io allows you to build Site Maps from different types of selectors. This system makes it possible to tailor data extraction to different site structures. Build scrapers, scrape sites and export data in CSV format directly from your browser. Use Web Scraper Cloud to export data in CSV, XLSX and JSON formats, access it via API, webhooks or get it exported via Dropbox, Google Sheets or Amazon S3.
