Reqable is a modern cross-platform project, designed for API development, testing, and debugging. Reqable fully supports HTTP1 and HTTP2 and partially supports HTTP3(QUIC).




Build a mock Rest API endpoint in seconds. Helps you in UI development, Webhooks, simulating delays, simulating exceptions and server errors, performance test, etc.



WireMock is a simulator for HTTP-based APIs. Some might consider it a service virtualization tool or a mock server.
MockServer can be used for mocking any system you integrate with via HTTP or HTTPS (i.e. services, web sites, etc).
SOAP/REST Mock Service is a simple configurable framework to mock out SOAP or RESTful (or "REST-like") webservices. It's main goal is to support automated integration testing of applications that integrate with 3rd party webservices.
Mockintosh is a mock server generator that's capable to generate RESTful APIs or communicate with message queues to mimick asyncronous tasks. Such that it enables software development teams to work independently while building and maintaining a complicated microservice...



Quickly define some REST or SOAP endpoints and have them return json/xml (dummy) data.








Collaboration based mock services with persistent data storage, git integration and intelligent proxying to quickly bring user flows to life.


Online API Mocking Tool: API Mock, fake API, stub API, simulate API, dummy API. Capture and debug requests instantly. Forward requests to localhost for webhooks testing and debugging. More than 100 random or faker shortcodes for response templating.



SmartMock.io is a tool to set up, manage, and troubleshoot HTTP protocol API mocks (REST, SOAP, JSON-RPC) in the cloud. This frees you up to focus on the logic of your mocks and not have to think about boilerplate code of your own HTTP mock servers.
