# Third-Party Add-ons for Protocol Buffers
This page lists code related to Protocol Buffers which is developed and maintained by third parties. You may find this code useful, but note that **these projects are not affiliated with or endorsed by Google (unless explicitly marked)**; try them at your own risk. Also note that many projects here are in the early stages of development and not production-ready.
If you have a project that should be listed here, please [send us a pull request](https://github.com/google/protobuf/pulls) to update this page.

## RPC Implementations
GRPC (http://www.grpc.io/) is Google's RPC implementation for Protocol Buffers. There are other third-party RPC implementations as well. Some of these actually work with Protocol Buffers service definitions (defined using the `service` keyword in `.proto` files) while others just use Protocol Buffers message objects.
