Reviewer scorecard
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
