Ask HN: Brag about open-source projects you're proud of

Do you have a github project with hundreds of commits, meticulous documentation, but only a handful of stars? Feel like you can't get the marketing sauce right?

I've talked with many developers who have been maintaining passion projects for years without any decent recognition of their efforts.

I'd like to do a little to change that! Please list the projects you are most proud of along with their project URLs. Go ahead and say why it's awesome.

I want to give a way (right in this comment thread) for people to self-promote those things that get overlooked.

Thanks.
