If you'd like your project listed here, please [let us know](mailto:kchodorow@google.com?subject=My project uses Bazel)!
A language-and-platform-neutral remote procedure call system. (Bazel is a supported, although not primary, build system.)
Catches common Java mistakes as compile-time errors. (Migration to Bazel is in progress.)
A Java code generator that allows you to create a builder by writing one function.
An ecosystem for building tools that work with code.
A collection of C++/Java opensource projects with BUILD files so they can be built with Bazel with out of box support for protobuf and grpc (maybe thrift).
A platform-independent GameBoy emulator.
Braintree, a PayPal subsidiary, develops payment solutions for websites and applications. They use Bazel for parts of their internal build and Paul Gross even posted a nice piece about how their switch to Bazel went.
Makani, now a Google subsidiary, develops energy kites and uses Bazel to build their software (including their embedded C++ software).
