simonhorlick/bazel_esp32

The project is a niche utility that applies the Bazel build system to the ESP32 Arduino ecosystem. With only 20 stars and no activity for nearly five years (1766 days), it is functionally obsolete. The defensibility is minimal (2/10) because it consists primarily of configuration logic (Starlark/BUILD files) for existing tools, which can be easily replicated or updated by any competent embedded engineer. In the current landscape, users looking for Bazel-based embedded development are more likely to use Google's 'Pigweed' or official ESP-IDF CMake-based tooling. The project lacks support for newer ESP32 variants (S2, S3, C3, C6) and modern Bazel features like Bzlmod. Frontier labs have zero interest in this space, but the project is already displaced by the natural evolution of the Espressif ecosystem and the lack of maintenance.
