xwax /is/ meant for end-users, but right at the beginning it only had actual live professional use in mind. I was literally DJ'ing in clubs at the time and I wanted the digital equivalent of playing vinyl records.

I was collaborating with a friend on the early versions, to see if it could be commercialised to provide a "house" system for radio studios and clubs (much like the house provides CDJs or turntables). Today that's superseded by DJs bringing their own laptops, of course.

I don't know much about Mixxx these days; that project was always much better set up to grow through a range of contributors (eg. with its scripting engine). But I think it's technical architecture is probably quite different.

Whereas, xwax was designed from day 1 with the idea it was a realtime system with very tight latencies, taking input from one audio interface and responding to it on another. That was fun on Linux (and FreeBSD!) systems of the early 2000s.
