Compass vs Less: What are the differences?

Developers describe Compass as "A Stylesheet Authoring Environment that makes your website design simpler to implement and easier to maintain". The compass core framework is a design-agnostic framework that provides common code that would otherwise be duplicated across other frameworks and extensions. On the other hand, Less is detailed as "The dynamic stylesheet language". Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.

Compass and Less can be primarily classified as "CSS Pre-processors / Extensions" tools.

"No vendor prefix CSS pain" is the primary reason why developers consider Compass over the competitors, whereas "Better than css" was stated as the key factor in picking Less.

Compass and Less are both open source tools. It seems that Less with 16.1K GitHub stars and 3.45K forks on GitHub has more adoption than Compass with 6.91K GitHub stars and 1.23K GitHub forks.

According to the StackShare community, Less has a broader approval, being mentioned in 498 company stacks & 169 developers stacks; compared to Compass, which is listed in 88 company stacks and 42 developer stacks.

      Cherokee
      Cherokee is highly efficient, extremely lightweight and provides rock solid stability. Among its many features there is one that deserves special credit: a user friendly interface called cherokee-admin that is provided for a no-hassle configuration of every single feature of the server.
      Protractor
      Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would.
      Sass
      Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.
      Animate.css
      It is a bunch of cool, fun, and cross-browser animations for you to use in your projects. Great for emphasis, home pages, sliders, and general just-add-water-awesomeness.
      PostCSS
      PostCSS is a tool for transforming CSS with JS plugins. These plugins can support variables and mixins, transpile future CSS syntax, inline images, and more.

      ReactQL is a React + GraphQL front-end starter kit. #JSX is a natural way to think about building UI, and it renders to pure #HTML in the browser and on the server, making it trivial to build server-rendered Single Page Apps. GraphQL via Apollo was chosen for the data layer; #GraphQL makes it simple to request just the data your app needs, and #Apollo takes care of communicating with your API (written in any language; doesn't have to be JavaScript!), caching, and rendering to #React.

      ReactQL is written in TypeScript to provide full types/Intellisense, and pick up hard-to-diagnose goofs that might later show up at runtime. React makes heavy use of Webpack 4 to handle transforming your code to an optimised client-side bundle, and in throws back just enough code needed for the initial render, while seamlessly handling import statements asynchronously as needed, making the payload your user downloads ultimately much smaller than trying to do it by hand.

      React Helmet was chosen to handle <head> content, because it works universally, making it easy to throw back the correct <title> and other tags on the initial render, as well as inject new tags for subsequent client-side views.

      styled-components, Sass, Less and PostCSS were added to give developers a choice of whether to build styles purely in React / JavaScript, or whether to defer to a #css #preprocessor. This is especially useful for interop with UI frameworks like Bootstrap, Semantic UI, Foundation, etc - ReactQL lets you mix and match #css and renders to both a static .css file during bundling as well as generates per-page <style> tags when using #StyledComponents.

      React Router handles routing, because it works both on the server and in the client. ReactQL customises it further by capturing non-200 responses on the server, redirecting or throwing back custom 404 pages as needed.

      Koa is the web server that handles all incoming HTTP requests, because it's fast (TTFB < 5ms, even after fully rendering React), and its natively #async, making it easy to async/await inside routes and middleware.

      Absolutely fantastic, not only does it allow for modularity but it is armed with the most useful features like colour operations and nested styles to make you achive more by writing LESS.

      Customise the UIkit Front-End Framework, because of that is used to create the application CSS. I prefer SASS but is equivalent.

      Sass library that was originally used on the current JourneyMaker app. We've been slowly removing it from the front end.

      We use Less to organize our CSS code with imports, variables, mixins, and more.
