Bitrise! Both the open source CLI (https://www.bitrise.io/cli) and bitrise.io (hosted service).

I'm obviously biased (CTO and Co-founder), but I love automation, that's why I'm part of the bitrise team in the first place ;)

The CLI is similar to something like rake, but the config lives in a single file which can be moved anywhere, and you can get a list of available "tasks" (workflows in the bitrise terminology) by running `bitrise workflows` or `bitrise run` without any parameter.

There's also an open source editor (UI) available for it (https://discuss.bitrise.io/t/offline-workflow-editor-workflo...), which is now part of the "base plugins" which gets installed by the Bitrise CLI. It's also really light weight, as the CLI is a single binary distribution (written in Go).
