I migrated a monorepo including C++, Kotlin, Java, TypeScript and Python to Bazel. It's no small feat, and the DX varies widely across languages and platforms, but it's absolutely worth it. `bazel test //...` from a fresh clone builds & tests everything including gRPC/protobuf code generation, custom code generation, downloading packages, toolchains and linters, dependencies between langs, test suites with coverage across multiple languages.

Integration testing is a breeze through data dependencies. The reproducibility guarantees means we can reference container image SHAs in our Terraform and if the image didn't change the deploy is a no-op.

Bazel is an outstanding build system that handily solves a lot of practical problems in software engineering. Not just "at scale". Practical problems at any scale.
