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
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
The Skeptic
Reality Check
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
The Futurist
Big Picture
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
Community Sentiment
“OpenAPI spec is great — the tooling ecosystem around it is what makes modern API development possible”
“Swagger UI is ugly but writing the spec first and generating client SDKs automatically saves so much time”
“OpenAPI 3.1 finally aligning with JSON Schema is a huge deal for the whole API tooling ecosystem”
“Generated a full TypeScript SDK from our API spec in 20 minutes — this should be standard practice”
