Open-Source Software

I find myself on GitHub more and more lately and found myself wondering what are your(all y'all's?) favorite Open-Source projects out there, no matter the category of software they are?

Fellow-forumer's, feel free to reply too :-)

My favorite open source projects are without a doubt Kate, Gimp, Openshot and a lot more

Firefox. 

Also, MPC-HC and SumatraPDF.

Why do I need a favorite project? I use so many that I can't list them all.

Because the lowly internet masterminds depict your necessitating a favorite as such?

 

Nah, I was just curious, as I'm just immersing myself into the Open-source world and my previous exposure was pretty much Firefox and Gimp...Maybe I should have called it "alternative recommendations" as opposed to favorites?
