HTTP Toolkit is a beautiful, cross-platform &amp; open-source HTTP(S) debugging proxy, analyzer &amp; client, with built-in support for modern tools from Docker to Android to GraphQL.

Setup with one click to start seeing exactly what your code is sending. Diff requests or responses, and explore overall metrics, to understand in depth. Change live traffic content, and simulate errors or performance problems to test your system. Rapidly prototype requests or responses, from real traffic or from scratch, and export to shareable traffic recordings or ready-to-use code.

Debug, test &amp; build with HTTP(S), with a powerful suite of tools designed for modern development.

SmartMock.io is a hosted service virtualization solution. We call this model Mock-As-A-Service or HTTP Mock Server.

It provides tools for you to set up, manage, and troubleshoot your HTTP protocol API mocks (REST, SOAP, JSON-RPC) in the cloud. This frees you up to focus on the logic of your HTTP API mocks and not have to think about boilerplate code, infrastructure, hosting, and hardware maintenance. Changes made in your HTTP API mocks are immediately available for mock clients, so you don&#39;t have to wait for time-consuming deployments of self-hosted mock services. SmartMock.io supports a broad spectrum of use cases that allow the mocking of not only simple, static services but also sophisticated, stateful ones.

Top Features:
- Static, Template, and Dynamic Responses - SmartMock.io supports three types of HTTP mocks: static, template, and dynamic. For the most uncomplicated use cases, static response bodies like JSON or XML are provided. You may also use Moustache templates and built-in helpers to to make responses more dynamic and production-like. The most complex problems may need the implementation of mocks logic in plain Javascript using the provided utility libraries.
- Stateless and Stateful Behaviors - Use the state feature to simulate multi-step interaction scenarios. Setting up states in live systems may be an error-prone and time-consuming task. Dynamic HTTP mocks can do this with only a few lines of code. This feature is especially useful for more advanced acceptance test use cases and to prepare frontend-rendered user interface demos.
- Simulate Timeouts and Network Failures - Test how your services behave in error and unexpected scenarios like long response times, request timeouts, connectivity issues, and malformed responses. With SmartMock.io, you can easily simulate these scenarios.
