APIs are everywhere. But building great developer tools around them is still harder than it should be. That’s where OpenAPI comes in.

I’ll show you how to use OpenAPI as a single source of truth to power everything: live documentation, client libraries, mock servers, test suites, and more.

We will see how how tools like Swagger, Postman, and Redoc use OpenAPI under the hood, and how you can use it to build your own smart developer experiences.

By the end of this talk, you’ll have the practical knowledge to start using OpenAPI to streamline your API development process and build better developer tools.
