It costs money, but for other readers, I've been using Buildkite[0] at two different companies across ~4 years now and it's great. It's _mostly_ self-hosted in that jobs run on your own hardware and Buildkite itself is only the job queue that your self-hosted agents pull work from. They also provide an elastic CI stack[1] so you can have auto-scaling workers running on AWS

You still own enough of it that if the service is down, you can just execute the scripts manually to build, test and deploy
