awesome-c Awesome

A curated list of C good stuff. This list contains only free software for code, and sellers who aren't evil for physical resources.

LOOKING FOR MAINTAINERS: This list is currently pretty much inactive. I'm looking for maintainers that can make it great again. See #26 for more info, but the process is simple: add or fix a couple of things in this list and you'll become a contributor to a 850+ stars list.

This list was previously maintained by @kozross. He decided to switch the list to a new platform, so I've decided to fork it so we could keep it on GitHub.
