Reviewer scorecard
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
