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.
