RoboHydra is a tool that helps developers and testers create realistic, dynamic web applications. It allows developers to create complex, customisable HTTP interactions and responses, and allows testers to simulate user behaviour and validate responses. It can be used to create mock web services, or to test the behaviour of web applications. It is capable of simulating different scenarios and can be used to test the performance of applications across different environments. RoboHydra is written in JavaScript and runs on Node.js, so it is platform-independent and can be used in Windows, Mac and Linux environments.
Discontinued The hosted version of RequestBin (http://requestb.in/) was discontinued in March 2018 due to ongoing abuse that made it very difficult to reliably maintain the site. The source is still available to set up your own self-hosted instance.
