API Simulator for Easy and Realistic API Simulations
Applications Heavily Depend on APIs
It is common for an application to depend on the APIs of a dozen or more other applications and components.
These direct dependencies in turn have their own API dependencies, which may depend on even more APIs and so on...
Problems with API Dependencies Hinder Testing and Development
Testing and development come to a halt when any one of the direct and transitive API dependencies is needed but unavailable.
Development of API Clients can be at standstill waiting for the delivery of new APIs.
External APIs charge pay-per-transaction fees even in non-production environments.
Often times API dependencies enforce rate limiting making performance testing impossible.
The Solution? API Simulations!
API Simulations imitate real APIs or APIs not built yet
API Simulations mimic the direct dependencies.
An API Simulation behaves and outputs static and dynamic data if it was "the real deal".
API Simulations are always available and every time with the right test data.
