A service that provides you with a new way to document, test, and build web APIs. StopLight automatically maps an API, and then provides tooling and services that let you mock, document, and test your API. The visual editor aims to cut down on design time, and is spec agnostic. It can generate OAI (Swagger) and RAML specification code on demand, ready to be shared or published to any API hosting platform. It also includes an HTTP request maker to send real requests to your API, and the Prism API Proxy to mock, validate, and transform requests for testing.
