gripmock - gRPC Mock Server

•    Go

---

GripMock is a mock server for GRPC services. It's using a .proto file to generate implementation of gRPC service for you. If you are already familiar with Apiary or WireMock for mocking API service and looking for similiar thing for GRPC then this is the perfect fit for that. Matched stub will be returned to GRPC service then further parse it to response the rpc call.

mockserver - MockServer enables easy mocking of any system you integrate with via HTTP or HTTPS with clients written in Java, JavaScript and Ruby

•    Java

---

A simple server to support mocking responses from any server / service that uses HTTP. The expectations that configure how the MockServer will respond and to incoming requests can be setup using any language that can create JSON. In simple client is provided to make this easy in Java.

karate - Test Automation Made Simple

•    Java

---

Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Assertions and HTML reports are built-in, and you can run tests in parallel for speed.

grpc-gateway - gRPC to JSON proxy generator following the gRPC HTTP spec

•    Go

---

grpc-gateway is a plugin of protoc. It reads gRPC service definition, and generates a reverse-proxy server which translates a RESTful JSON API into gRPC. This server is generated according to the google.api.http annotation in your gRPC service definition. It helps you to provide your APIs in both gRPC and RESTful style at the same time.

grpc-web - gRPC Web implementation for Golang and TypeScript

•    TypeScript

---

gRPC-Web is a cutting-edge spec that enables invoking gRPC services from modern browsers. If you are looking for gRPC support for Node.js there is an official Node.js gRPC library. This package supports Node.js, but requires that the server has the gRPC-Web compatibility layer (read on to understand more).

Keploy - No code API testing platform. Create unit tests and data mocks from API calls

•    Go

---

Keploy is a no-code testing platform that generates tests from API calls. It converts API calls into testcases. Mocks are automatically generated with the actual request/responses.

go-microservice-helpers - A collection of handy snippets that simplify creation of GRPC servers and clients

•    Go

---

A collection of handy snippets that simplify creation of GRPC servers and clients. The provided helpers allow to create grpc endpoints with zipkin distributed tracing pre-configured; spawn http servers that serve both grpc and common http traffic; simplify golang crypto primitives to load EC keys.

grpc-proxy - gRPC proxy is a Go reverse proxy that allows for rich routing of gRPC calls with minimum overhead

•    Go

---

The project now exists as a proof of concept, with the key piece being the proxy package that is a generic gRPC reverse proxy handler. The package proxy contains a generic gRPC reverse proxy handler that allows a gRPC server to not know about registered handlers or their data types. Please consult the docs, here's an exaple usage.

go-grpc-middleware - Golang gRPC Middlewares: interceptor chaining, auth, logging, retries and more.

•    Go

---

gRPC Go Middleware: interceptors, helpers, utilities. gRPC Go recently acquired support for Interceptors, i.e. middleware that is executed either on the gRPC Server before the request is passed onto the user's application logic, or on the gRPC client either around the user call. It is a perfect way to implement common patterns: auth, logging, message, validation, retries or monitoring.

go-grpc-prometheus - Prometheus monitoring for your gRPC Go servers.

•    Go

---

Prometheus monitoring for your gRPC Go servers and clients. A sister implementation for gRPC Java (same metrics, same semantics) is in grpc-ecosystem/java-grpc-prometheus.

grpc-elixir - The Elixir implementation of gRPC

•    Elixir

---

The Elixir implementation of gRPC. You can start the gRPC server as a supervised process. First, add GRPC.Server.Supervisor to your supervision tree.

grpcurl - Like cURL, but for gRPC: Command-line tool for interacting with gRPC servers

•    Go

---

grpcurl is a command-line tool that lets you interact with gRPC servers. It's basically curl for gRPC servers. The main purpose for this tool is to invoke RPC methods on a gRPC server from the command-line. gRPC servers use a binary encoding on the wire (protocol buffers, or "protobufs" for short). So they are basically impossible to interact with using regular curl (and older versions of curl that do not support HTTP/2 are of course non-starters). This program accepts messages using JSON encoding, which is much more friendly for both humans and scripts.

bloomrpc - GUI Client for GRPC Services

•    TypeScript

---

The missing GUI Client for GRPC services. Inspired by Postman and GraphQL Playground. BloomRPC aim to give the simplest and efficient developer experience for exploring and querying your GRPC services.

grpcc - A gRPC cli interface for easy testing against gRPC servers

•    Javascript

---

grpcc is a flexible command-line client for any gRPC server for quick and easy testing of APIs. grpcc is written in nodejs but can talk to a gRPC service written in any language. By default, grpcc will attempt to make a secure connection to the service. If you need an insecure connection, you can pass in the -i flag.

grpc-rs - The gRPC library for Rust built on C Core library and futures

•    Rust

---

gRPC-rs is a Rust wrapper of gRPC Core. gRPC is a high performance, open source universal RPC framework that puts mobile and HTTP/2 first. For Linux and MacOS, you also need to install gcc 4.9+ (or clang) too.

grpc-web - gRPC for Web Clients

•    C++

---

gRPC-Web provides a Javascript library that lets browser clients access a gRPC service. You can find out much more about gRPC in its own website. The current release is a Beta release, and we expect to announce General-Availability by Oct. 2018.

gRPC-Java - The Java gRPC implementation. HTTP/2 based RPC

•    Java

---

In gRPC a client application can directly call methods on a server application on a different machine as if it was a local object, making it easier for you to create distributed applications and services. As in many RPC systems, gRPC is based around the idea of defining a service, specifying the methods that can be called remotely with their parameters and return types.

grpc-dotnet - gRPC for .NET

•    CSharp

---

gRPC is a modern, open source, high-performance remote procedure call (RPC) framework that can run anywhere. gRPC enables client and server applications to communicate transparently, and simplifies the building of connected systems. For more information, see An introduction to gRPC on .NET.

Mock Service Worker - Seamless REST/GraphQL API mocking library for browser and Node

•    Javascript

---

Mock by intercepting requests on the network level. Seamlessly reuse the same mock definition for testing, development, and debugging. Browser usage is what sets Mock Service Worker apart from other tools. Utilizing the Service Worker API that intercepts requests for the purpose of caching, Mock Service Worker responds to captured requests with your mock definition on the network level. This way your application knows nothing about the mocking.
