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.

      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.
