api-mock - Creates a mock server based on an API Blueprint

•    HTML

---

This project is no longer under active development and we're looking for a new maintainer (or owner). Please open an issue if you are interested in helping out. API-Mock is a node.js npm module that generates a mock server (express) from your API specification. Document your API in the API blueprint format, and API-Mock mocks your routes and sends the responses defined in the api spec.

Smocker - Simple and efficient HTTP mock server

•    Go

---

Smocker (server mock) is a simple and efficient HTTP mock server. Smocker exposes two ports: Port 8080 is the mock server port. It will expose the routes you register through the configuration port and Port 8081 is the configuration port. It's the port you will use to register new mocks. This port also exposes a user interface.

Wiremock - A tool for mocking HTTP services

•    Java

---

WireMock is a simulator for HTTP-based APIs. Some might consider it a service virtualization tool or a mock server. It enables you to stay productive when an API you depend on doesn't exist or isn't complete. It supports testing of edge cases and failure modes that the real API won't reliably produce. And because it's fast it can reduce your build time from hours down to minutes.

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.

httplive - HTTP Request & Response Service, Mock HTTP

•    Go

---

The HttpLive is a tool for API designers, Proxy, mobile and web application developers to develop and test their applications faster without being dependent on any server or backend applications. HttpLive has a built-in user interface. Therefore, you can do all the configurations you need on this UI, and with dynamic URL (Routing) definitions you can specify your own JSON return types for your applications.

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.

drakov - Mock Server that implements the API Blueprint specification

•    Javascript

---

We have setup a google group to assist with the answering of questions any users of Drakov may have. Since version 1.0.2, a version of the Drafter package is being used, which attempts to install the version with C bindings (faster), but falls back if compilation of this package fails to Drafter.js.

apimocker - node.js module to run a simple http server for mock service responses.

•    Javascript

---

Then you can visit "http://localhost:7878/first" in your browser to see it work. The quiet and port options can also be set in the config.json file, and values from config.json will override values from the command line. After you get up and running, you should put your config.json and mock responses in a better location. It's not a good idea to keep them under the "node_modules" directory. Make sure another process is not already using the port you want. If you want port 80, you may need to use "sudo" on Mac OSX. Sometimes you only want some service endpoints to be mocked, but have other requests forwarded to real service endpoints. In this case, provide the proxy URL option on startup e.g. apimocker --proxy http://myrealservice.io When the proxy option is set, any requests to apimocker with URLs that are not configured with mock files, will be forwarded to the specified URL.

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.

FakeRest - Patch fetch/XMLHttpRequest to fake a REST API server in the browser, based on JSON data.

•    Javascript

---

Intercept AJAX calls to fake a REST server based on JSON data. Use it on top of Sinon.js (for XMLHTTPRequest) or fetch-mock (for fetch) to test JavaScript REST clients on the browser side (e.g. single page apps) without a server. FakeRest uses a standard REST flavor, described below.

dyson - Node server for dynamic, fake JSON.

•    Javascript

---

Node server for dynamic, fake JSON. When developing client-side applications, often either static JSON files, or an actual server, backend, datastore, or API, is used. Sometimes static files are too static, and sometimes an actual server is not available, not accessible, or too tedious to set up.

graphql-faker - 🎲 Mock or extend your GraphQL API with faked data. No coding required.

•    TypeScript

---

Mock your future API or extend the existing API with realistic data from faker.js. No coding required. All you need is to write GraphQL IDL. Don't worry, we will provide you with examples in our IDL editor. In the GIF bellow we add fields to types inside real GitHub API and you can make queries from GraphiQL, Apollo, Relay, etc. and receive real data mixed with mock data.
