TLDR: Bazel is definitely worth to use on your projects even though it has minimum supports of some languages such as C#. Prologue Before I was interested in bazel, I always thought why bother to learn a new building system even I knew that kubernetes once was built with bazel. 4 months ago, I was involved in a micro service structured project. I was dissatisfied with dev workflow using skaffold and I looked other options in the market.
