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.

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.

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.

Mock SMTP Server

The Mock SMTP Server is a simple email server that only displays each email message it receives in the application window. It is intented to test applications that send email. It will not store or relay email. Only the minimum requirements of RFC 5321 are implemented.

SimulatorRemoteNotifications - Library to send mock remote notifications to the iOS simulator

•    Objective-C

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.

•    Javascript

JSON Server is a full fake REST API with zero coding in less than 30 seconds Created with <3 for front-end developers who need a quick back-end for prototyping and mocking.

node-mitm - Intercept and mock outgoing Node

•    Javascript

Mitm.js is a library for Node.js (and Io.js) to intercept and mock outgoing network TCP and HTTP connections. Mitm.js intercepts and gives you a Net.Socket to communicate as if you were the remote server. For HTTP requests it even gives you Http.IncomingMessage and Http.ServerResponse — just like you're used to when writing Node.js servers. Except there's no actual server running, it's all just In-Process Interception™. Intercepting connections and requests is extremely useful to test and ensure your code does what you expect. Assert on request parameters and send back various responses to your code without ever having to hit the real network. Fast as hell and a lot easier to develop with than external test servers.

node-mocks-http - Mock 'http' objects for testing Express routing functions

•    Javascript

Mock 'http' objects for testing Express routing functions, but could be used for testing any Node.js web server applications that have code that requires mockups of the request and response objects. This project is available as a NPM package.

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.

zan-proxy - An extensible proxy for PC/Mobile/APP developer

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.

cpp-jwt - JSON Web Token library for C++

•    C++

JSON Web Token(JWT) is a JSON based standard (RFC-7519) for creating assertions or access tokens that consists of some claims (encoded within the assertion). This assertion can be used in some kind of bearer authentication mechanism that the server will provide to clients, and the clients can make use of the provided assertion for accessing resources. This provides JWT client support in C++.
