At 9elements we do firmware, which is rather niche and complicated. As developing firmware is already difficult enough, we think that building / compiling it should not be. Which is the reason why we made firmware-action -- an automation tool to build firmware, powered by Dagger that can be used on your local machine as well as in CI/CD pipelines.
