This free online tool for testing APIs looks at functionality and performance. SaaS startup API Tester is a cloud-based testing framework designed for application programming interface (API) developers as well as software quality assurance engineers and operators. The application performance monitoring system enables people to "build and save scripts for testing the speed, reliability and functionality of internally managed and third party APIs."

The API Tester interface allows you to make up and deliver tests easily from AWS, as well as save tests for later use and share test configurations with friends. Described as the easiest way for testing APIs, the computing solution also allows you to view the run history, create and re-run tests when saved.
