Reviewer scorecard
“Real-time reactivity without WebSocket boilerplate. Server functions co-located with schema definition is elegant.”
“Guaranteed valid JSON from LLMs — no retry loops needed. The FSM approach is mathematically elegant and reliable.”
“The DX is genuinely excellent. If your app needs real-time, Convex eliminates an enormous amount of complexity.”
“If you need structured outputs from open models, Outlines is the correct solution. Not a hack, but a proper constraint system.”
“Reactive backends that push data to clients will become the default. Convex is building that future now.”
“Constrained generation will be built into every inference engine. Outlines pioneered the approach.”
