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 *none of these projects are affiliated with or endorsed by Google*; 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 a message to the discussion group:

RPC Implementations

These are RPC implementations that work with Protocol Buffers. 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.
