Our Recommendation
Choose Convex for modern TypeScript projects where developer experience matters. Pick Firebase for production apps that need Google's ecosystem and proven scale.
“The best tool depends on what you are building and how you work. There is no universal winner. Pick the one that fits your workflow and budget, then ship something.”

Overview
Convex and Firebase are both backend platforms with real-time capabilities but come from different eras. Firebase, backed by Google, is an established platform with a massive ecosystem covering databases, authentication, hosting, analytics, and machine learning. Convex is a newer platform built with modern TypeScript development in mind, offering end-to-end type safety, reactive queries, and a developer experience optimised for the current JavaScript ecosystem.
Data Model and Queries
Convex uses a document-relational model with TypeScript-defined schemas and reactive queries that automatically update when data changes. Firebase's Firestore is a document database with real-time listeners but requires more manual subscription management. Convex's approach is more elegant for applications with complex data relationships, while Firestore's simpler model works well for straightforward document storage.
Frequently Asked Questions
Is Convex production-ready?
Yes. Convex is used in production by many companies, though Firebase has a longer track record and larger scale deployments.
Does Convex support authentication?
Convex integrates with Clerk and Auth0 for authentication. Firebase has its own built-in auth system.
Which scales better?
Firebase, backed by Google Cloud, handles massive scale with proven infrastructure. Convex scales well but has less public track record at extreme volumes.
