🆚 HTML vs. Rack

Hypertext Markup Language (HTML) is a markup language used to create web pages and is the de facto standard for documents displayed in web browsers.

It defines the structure of web content using elements for text, links, images, forms, tables, and embedded media, organizes documents into a hierarchical DOM, and enables hyperlinking between pages, which is a fundamental mechanism of the World Wide Web.

Rack is a minimal, modular interface and invocation convention that operates between Ruby web servers and web applications to standardize how HTTP requests and responses are exchanged.

It translates raw HTTP requests into a CGI-style environment defined by RFC 3875, supports middleware stacking for step-by-step request and response processing, and is implemented by servers such as Phusion Passenger, Puma, Unicorn, and Thin.
