Bazel Build Event Protocol

The Build Event Protocol (BEP) is Bazel's structured stream of build events — target configured, progress, test results, action executed, build finished — emitted during every invocation. BEP can be written to a local file (--build_event_json_file / --build_event_binary_file) or streamed via gRPC to a Build Event Service (BES) backend for build observability, flake analysis, and CI dashboards.
