I maintain (somewhat sporadically at least) a set of Protobuf and gRPC rules for a wide variety of languages under the Bazel build system. These rules allow integrating a consistent toolchain for generating language-specific sources and libraries from your .proto files. If you or your company are finding these rules useful, please consider supporting their development, even if just with a coffee ☕. The tiers listed are mostly meaningless and you are free to enter any value you like, as I am trying to be transparent that it's merely supporting the projects already openly available; so anything is appreciated and I aim to support regardless of sponsorship.
