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. 90 91 * https://github.com/grpc/grpc (C++, Node.js, Python, Ruby, Objective-C, PHP, C#, Google-official implementation) 92 * http://zeroc.com/ice.html (Multiple languages) 93 * http://code.google.com/p/protobuf-net/ (C#/.NET/WCF/VB) 94 * https://launchpad.net/txprotobuf/ (Python) 95 * https://github.com/modeswitch/protobuf-rpc (Python) 96 * http://code.google.com/p/protobuf-socket-rpc/ (Java, Python) 97 * http://code.google.com/p/proto-streamer/ (Java) 98 * http://code.google.com/p/server1/ (C++) 99 * http://deltavsoft.com/RcfUserGuide/Protobufs (C++) 100 * http://code.google.com/p/protobuf-mina-rpc/ (Python client, Java server) 101 * http://code.google.com/p/casocklib/ (C++) 102 * http://code.google.com/p/cxf-protobuf/ (Java) 103 * http://code.google.com/p/protobuf-remote/ (C++/C#) 104 * http://code.google.com/p/protobuf-rpc-pro/ (Java) 105 * https://code.google.com/p/protorpc/ (Go/C++) 106 * https://code.google.com/p/eneter-protobuf-serializer/ (Java/.NET) 107 * http://www.deltavsoft.com/RCFProto.html (C++/Java/Python/C#) 108 * https://github.com/robbinfan/claire-protorpc (C++) 109 * https://github.com/BaiduPS/sofa-pbrpc (C++) 110 * https://github.com/ebencheung/arab (C++) 111 * http://code.google.com/p/protobuf-csharp-rpc/ (C#) 112 * https://github.com/thesamet/rpcz (C++/Python, based on ZeroMQ) 113 * https://github.com/w359405949/libmaid (C++, Python) 114 * https://github.com/madwyn/libpbrpc (C++) 115 116 ## Other Utilities 117 118 There are miscellaneous other things you may find useful as a Protocol Buffers developer. 119 120 * [NetBeans IDE plugin](http://code.google.com/p/protobuf-netbeans-plugin/) 121 * [Wireshark/Ethereal packet sniffer plugin](http://code.google.com/p/protobuf-wireshark/) 122 * [Alternate encodings (JSON, XML, HTML) for Java protobufs](http://code.google.com/p/protobuf-java-format/) 123 * [Another JSON encoder/decoder for Java](https://github.com/sijuv/protobuf-codec) 124 * [Editor for serialized protobufs](http://code.google.com/p/protobufeditor/) 125 * [Intellij IDEA plugin](http://github.com/nnmatveev/idea-plugin-protobuf) 126 * [TextMate syntax highlighting](http://github.com/michaeledgar/protobuf-tmbundle) 127 * [Oracle PL SQL plugin](http://code.google.com/p/protocol-buffer-plsql/) 128 * [Eclipse editor for protobuf (from Google)](http://code.google.com/p/protobuf-dt/) 129 * [C++ Builder compatible protobuf](https://github.com/saadware/protobuf-cppbuilder) 130 * Maven Protocol Compiler Plugin 131 * https://github.com/sergei-ivanov/maven-protoc-plugin/ 132 * http://igor-petruk.github.com/protobuf-maven-plugin/ 133 * http://code.google.com/p/maven-protoc-plugin/ 134 * https://github.com/os72/protoc-jar-maven-plugin 135 * [Documentation generator plugin (Markdown/HTML/DocBook/...)](https://github.com/estan/protoc-gen-doc) 136 * [DocBook generator for .proto files](http://code.google.com/p/protoc-gen-docbook/) 137 * [Protobuf for nginx module](https://github.com/dbcode/protobuf-nginx/) 138 * [RSpec matchers and Cucumber step defs for testing Protocol Buffers](https://github.com/connamara/protobuf_spec) 139 * [Sbt plugin for Protocol Buffers](https://github.com/Atry/sbt-cppp) 140 * [Gradle Protobuf Plugin](https://github.com/aantono/gradle-plugin-protobuf) 141 * [Multi-platform executable JAR and Java API for protoc](https://github.com/os72/protoc-jar) 142 * [Python scripts to convert between Protocol Buffers and JSON](https://github.com/NextTuesday/py-pb-converters) 143 * [Visual Studio Language Service support for Protocol Buffers](http://visualstudiogallery.msdn.microsoft.com/4bc0f38c-b058-4e05-ae38-155e053c19c5) 144 * [C++ library for serialization/de-serialization between Protocol Buffers and JSON.](https://github.com/yinqiwen/pbjson) 145 * [ProtoBuf with Java EE7 Expression Language 3.0; pure Java ProtoBuf Parser and Builder.](https://github.com/protobufel/protobuf-el) 146 * [Notepad++ Syntax Highlighting for .proto files](https://github.com/chai2010/notepadplus-protobuf) 147 * [Linter for .proto files](https://github.com/ckaznocha/protoc-gen-lint) 148
