# 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. ## Programming Languages These are projects we know

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. * https://github.com/grpc/grpc (C++, Node.js, Python, Ruby, Objective-C, PHP, C#, Google-official implementation) * http://zeroc.com/ice.html (Multiple languages) * http://code.google.com/p/protobuf-net/ (C#/.NET/WCF/VB) * https://launchpad.net/txprotobuf/ (Python) * https://github.com/modeswitch/protobuf-rpc (Python) * http://code.google.com/p/protobuf-socket-rpc/ (Java, Python) * http://code.google.com/p/proto-streamer/ (Java) * http://code.google.com/p/server1/ (C++) * http://deltavsoft.com/RcfUserGuide/Protobufs (C++) * http://code.google.com/p/protobuf-mina-rpc/ (Python client, Java server) * http://code.google.com/p/casocklib/ (C++) * https://protojure.github.io (Clojure) * http://code.google.com/p/cxf-protobuf/ (Java) * http://code.google.com/p/protobuf-remote/ (C++/C#) * http://code.google.com/p/protobuf-rpc-pro/ (Java) * https://code.google.com/p/eneter-protobuf-serializer/ (Java/.NET) * http://www.deltavsoft.com/RCFProto.html (C++/Java/Python/C#) * https://github.com/robbinfan/claire-protorpc (C++) * https://github.com/BaiduPS/sofa-pbrpc (C++) * https://github.com/ebencheung/arab (C++) * http://code.google.com/p/protobuf-csharp-rpc/ (C#) * https://github.com/thesamet/rpcz (C++/Python, based on ZeroMQ) * https://github.com/w359405949/libmaid (C++, Python) * https://github.com/madwyn/libpbrpc (C++) * https://github.com/SeriousMa/grpc-protobuf-validation (Java) * https://github.com/tony612/grpc-elixir (Elixir) * https://github.com/johanbrandhorst/protobuf (GopherJS) * https://github.com/awakesecurity/gRPC-haskell (Haskell) * https://github.com/Yeolar/raster (C++) * https://github.com/jnordberg/wsrpc (JavaScript Node.js/Browser) * https://github.com/ppissias/xsrpcj (Java) ## Other Utilities There are miscellaneous other things you may find useful as a Protocol Buffers developer. * [Bazel Build](https://bazel.build) * [rules_closure](https://github.com/bazelbuild/rules_closure) `js-closure` * [rules_go](https://github.com/bazelbuild/rules_go) `go` * [rules_protobuf](https://github.com/pubref/rules_protobuf) `java` `c++` `c#` `go` `js-closure` `js-node` `python` `ruby` * [NetBeans IDE plugin](http://code.google.com/p/protobuf-netbeans-plugin/) * [Wireshark/Ethereal packet sniffer plugin](http://code.google.com/p/protobuf-wireshark/) * [Alternate encodings (JSON, XML, HTML) for Java protobufs](http://code.google.com/p/protobuf-java-format/) * [Another JSON encoder/decoder for Java](https://github.com/sijuv/protobuf-codec) * [Editor for serialized protobufs](http://code.google.com/p/protobufeditor/) * [Intellij IDEA plugin](http://github.com/nnmatveev/idea-plugin-protobuf) * [TextMate syntax highlighting](http://github.com/michaeledgar/protobuf-tmbundle) * [Oracle PL SQL plugin](http://code.google.com/p/protocol-buffer-plsql/) * [Eclipse editor for protobuf (from Google)](http://code.google.com/p/protobuf-dt/) * [C++ Builder compatible protobuf](https://github.com/saadware/protobuf-cppbuilder) * Maven Protobuf Compiler Plugin * By xolstice.org ([Documentation](https://www.xolstice.org/protobuf-maven-plugin/)) ([Source](https://github.com/xolstice/protobuf-maven-plugin/)) [![Maven Central](https://img.shields.io/maven-central/v/org.xolstice.maven.plugins/protobuf-maven-plugin.svg)](https://repo1.maven.org/maven2/org/xolstice/maven/plugins/protobuf-maven-plugin/) * http://igor-petruk.github.com/protobuf-maven-plugin/ * http://code.google.com/p/maven-protoc-plugin/ * https://github.com/os72/protoc-jar-maven-plugin * [Documentation generator plugin (Markdown/HTML/DocBook/...)](https://github.com/pseudomuto/protoc-gen-doc) * [DocBook generator for .proto files](http://code.google.com/p/protoc-gen-docbook/) * [Protobuf for nginx module](https://github.com/dbcode/protobuf-nginx/) * [RSpec matchers and Cucumber step defs for testing Protocol Buffers](https://github.com/connamara/protobuf_spec) * [Sbt plugin for Protocol Buffers](https://github.com/Atry/sbt-cppp) * [Gradle Protobuf Plugin](https://github.com/aantono/gradle-plugin-protobuf) * [Multi-platform executable JAR and Java API for protoc](https://github.com/os72/protoc-jar) * [Python scripts to convert between Protocol Buffers and JSON](https://github.com/NextTuesday/py-pb-converters) * [Visual Studio Language Service support for Protocol Buffers](http://visualstudiogallery.msdn.microsoft.com/4bc0f38c-b058-4e05-ae38-155e053c19c5) * [Visual Studio Code Support for Protocol Buffers](https://marketplace.visualstudio.com/items?itemName=zxh404.vscode-proto3) * [C++ library for serialization/de-serialization between Protocol Buffers and JSON.](https://github.com/yinqiwen/pbjson) * [ProtoBuf with Java EE7 Expression Language 3.0;
