OpenAPI (formerly Swagger) is the standard for describing REST APIs. Swagger UI for documentation, codegen for clients/servers, and a massive ecosystem of tools.
Reviewer scorecard
“Mature API, excellent SDKs, and the content model is flexible. The enterprise choice for headless CMS.”
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“Expensive for what it is. Sanity and Payload offer better DX at lower cost. Only justified for enterprise compliance needs.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“The editor experience is functional but uninspiring. Sanity's customizable studio is more pleasant to work in.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
