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
“This is the kind of tool that makes you wonder how you worked without it.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“The free tier is genuinely usable. Rare for this category.”
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
