Reviewer scorecard
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Eliminates 90% of server state management boilerplate. Caching, refetching, and mutations just work.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Solved server state management so well that it changed how React apps are built. The devtools are excellent.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
“TanStack Query's multi-framework support and the broader TanStack ecosystem are defining modern web data management.”
