The problem this solves is that distsys devs don't get enough feedback. You say you use docker-compose. Compared to docker-compose, Tilt has two advantages:
1) It updates the services as you edit them
2) Its UI makes it easy to see where errors are occurring, without you having to play 20 questions on the command-line or worry about things scrolling off-screen.
The Tiltfile doesn't redefine your k8s definitions; it reuses your existing k8s definitions. The Tiltfile just tells Tilt how to get them. (Many teams don't just use yaml files, but generate them, so Tilt has to be able to do that, too.)
There is a landing page at https://tilt.build which has more of the "why Tilt". Also, we're adding native support for docker-compose next week. I'd love to understand your case more, because at a high level you sound like exactly the kind of dev we want to help.
