Convex vs Firebase
Side-by-side comparison of features, pricing, ratings, and alternatives.
Convex provides a fully managed backend platform that includes a reactive, versioned database, serverless functions, and file storage. It syncs data in real time across web and mobile clients, eliminating the need for custom server infrastructure. Developers can write TypeScript functions that run automatically on data changes, query the database with a simple API, and leverage built‑in authentication and scaling. The platform is designed for rapid iteration and production‑grade reliability.
Firebase is Google’s app development platform offering a realtime NoSQL database (Firestore), authentication, hosting, cloud functions, and analytics, popular for quickly building web and mobile apps. It abstracts away backend infrastructure.

4.0 (2)Great backend
Been using Firebase for a while. Realtime sync. Minor gripe: costs can spike at scale. Would recommend.
Recommend Firebase
Firebase has been part of our stack. Realtime sync. Minor gripe: nosql data modeling constraints. Would recommend.
