Compare Builder.io vs Convex

It depends on your use case: Builder.io is for shipping UI and pages, Convex is for building the backend behind them.

Builder.io focuses on Figma-to-code, a no-code visual editor, a headless CMS and A/B testing, so designers and marketers can ship pages without waiting on developers. It doesn't generate backend code such as a database, authentication or server logic, and works as a visual layer on top of an existing codebase. Convex covers exactly that gap, with real-time queries, built-in auth, file storage, scheduled functions and vector search, all in TypeScript and self-hostable. Frontend-leaning developers say its reactive model syncs changes across users with no extra effort and spares them a separate query language.

⚠ Teams report that wiring up their component library and setting up governance took more effort than they expected.

Choose Convex if…

Choose Convex if you need a real-time backend with database, auth and APIs in TypeScript without hand-managing WebSockets or caches.

⚠ Teams heavily invested in PostgreSQL or MySQL, or needing row-level security policies or multi-region active-active deployments, may find it limiting.
