libsass-python: Sass/SCSS for Python

This package provides a simple Python extension module sass which is binding Libsass (written in C/C++ by Hampton Catlin and Aaron Leung). It’s very straightforward and there isn’t any headache related Python distribution/deployment. That means you can add just libsass into your‘s install_requires list or requirements.txt file.

It currently supports CPython 2.6, 2.7, 3.3–3.5, and PyPy 2.3+!


  • You don’t need any Ruby/Node.js stack at all, for development or deployment either.
  • Fast. (Libsass is written in C++.)
  • Simple API. See example code for details.
  • Custom functions.
  • @import callbacks.
  • Support both tabbed (Sass) and braces (SCSS) syntax.
  • WSGI middleware for ease of development. It automatically compiles Sass/SCSS files for each request. See also sassutils.wsgi for details.
  • setuptools/distutils integration. You can build all Sass/SCSS files using build_sass command. See also sassutils.distutils for details.
  • Works also on PyPy.
  • Provides prebuilt wheel (PEP 427) binaries for Windows and Mac.


It’s available on PyPI, so you can install it using pip:

$ pip install libsass


libsass requires some features introduced by the recent C++ standard. You need a C++ compiler that support those features. See also libsass project’s README file.


>>> import sass
>>> sass.compile(string='a { b { color: blue; } }')
'a b {\n  color: blue; }\n'

Hampton Catlin and Aaron Leung wrote Libsass, which is portable C/C++ implementation of SASS.

Hampton Catlin originally designed SASS language and wrote the first reference implementation of it in Ruby.
