Reviewer scorecard
“Real-time reactivity without WebSocket boilerplate. Server functions co-located with schema definition is elegant.”
“Agents sharing solutions with other agents — this is how agent ecosystems should work. The Mozilla backing gives it credibility and staying power.”
“The DX is genuinely excellent. If your app needs real-time, Convex eliminates an enormous amount of complexity.”
“Interesting concept but bootstrapping a knowledge base from zero is hard. Stack Overflow took years to become useful. Agent queries are even more varied.”
“Reactive backends that push data to clients will become the default. Convex is building that future now.”
“This is the emergence of collective agent intelligence. Individual agents learning from the swarm. Mozilla is building infrastructure for the agentic web.”
