Is there something similar to nib for sass?

Question

Sass

Good afternoon, I always use stylus + nib, nib includes various blends, prefixes, prefixes for gradients with fixes for ie, clearfix(), custom-functions like: berder-radius(), box-shodw(), etc.
Now I am working in a new project and the customer requires the use of sass, please tell me what can be used for autoprefixes, in general, everything that the nib library includes, there may be similar packs for sass.
There is no time to search now.

Answer 1

There are similar things for sass - compass, bourbon.
For prefixes, use an autoprefixer, not preprocessor mixins (whatever).

Answer 2

In general, sass is kind of. I don’t know why they came up with it, apparently, so that people’s lives would become more difficult, and bootstrap too. Stack hat = bootstap plus sas bueeeeee
