Swagger / OpenAPI

API documentation and design standard

OpenAPI (formerly Swagger) is the standard for describing REST APIs. Swagger UI for documentation, codegen for clients/servers, and a massive ecosystem of tools.

Panel Reviews

The Builder

Developer Perspective

Ship

“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”

The Skeptic

Reality Check

Ship

“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”

The Futurist

Big Picture

Ship

“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
