This was created for manual testing of multiple scenarios while integrating with external APIs. We wanted something simple hosted, we didn't want this to be deployed multiple environments with config files or one environment where people might unintentionally overwrite or conflict with other's files. Creating stubs via web was easier was developers, QA's and SMEs testing the product.

Though you could use this for automated tests, I request you to wait till I get a better server with higher availability. For automated integration tests there other great stub servers in different languages.
