I'll engage in some expectation management: ag doesn't cover all uses of Ack. I made ag because I loved Ack, but it wasn't fast enough for my needs. For the features of Ack that I use, ag is interchangeable. For features I don't use... not so much. Also, since the release of Ack 2.0, some behaviors and command line options have differed slightly.

If you want to know why ag is so fast, there's a summary in the GitHub README.[1] I've also written a few blog posts on the subject.[2]
