We're different in a couple of ways right now: - they focus on open source, we focus on web apps. - you can set Circle up in one click - Circle is much much faster - Circle allows you to parallelize your tests across multiple machines - Circle supports deployment That is my biased opinion of course. Both TravisCI and Circle are new technologies in a new market, so I would expect this to change over time, but that's the way it is now.
