Our Recommendation
Choose Convex for new TypeScript projects where developer experience is a priority. Pick Firebase for production apps needing Google's proven infrastructure.
“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.”
When to Choose Each Tool
Choose Convex
Starting a new TypeScript project
Choose Firebase
Need Google's ecosystem or proven scale
Overview
Convex and Firebase both provide backend infrastructure with real-time capabilities. Firebase is Google's established platform with a massive ecosystem. Convex is a modern platform built specifically for TypeScript developers, with reactive queries, type-safe functions, and an excellent developer experience. Firebase is proven at scale; Convex is better to work with day-to-day.
Developer Experience
Convex's TypeScript-first approach means your queries, mutations, and schema are all defined in TypeScript with full type safety from database to frontend. Firebase's SDK is well-designed but cannot match the end-to-end type safety that Convex provides. For TypeScript-heavy teams, Convex's DX advantage is substantial.
Frequently Asked Questions
Is Convex mature enough for production?
Yes. Convex is production-ready and used by many companies, though Firebase has a longer track record at very large scale.
Can I migrate from Firebase to Convex?
Yes, but it requires rewriting your backend code. The data models and APIs are fundamentally different.
Which is cheaper?
Convex starts at $25/month with predictable pricing. Firebase is pay-as-you-go, which can be cheaper for low usage but unpredictable at scale.
