Chef is Convex’s prompt-to-app builder, distinguished from most “vibecoding” app generators by actually understanding backend concerns: it scaffolds a real Convex database schema, server functions, and authentication alongside the frontend, rather than generating UI backed by mock data.

Why it stands out

Backend-aware from the start, applying real data-modeling and server-function patterns instead of a frontend-only demo.
Open source, giving full visibility and control over the generated app and workflow.
Built on Convex’s reactive backend, so generated apps get real-time data syncing by default.

Good for

Prototyping full-stack apps that need a real, working backend from the first generation, not just a UI mockup.
