Reviewer scorecard
“Real-time reactivity without WebSocket boilerplate. Server functions co-located with schema definition is elegant.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“The DX is genuinely excellent. If your app needs real-time, Convex eliminates an enormous amount of complexity.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Reactive backends that push data to clients will become the default. Convex is building that future now.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
