Firebase (Google Cloud)

+5-3

Pros

  • Built-in Firebase Authentication with 15+ OAuth providers (Google, GitHub, Apple, Facebook, Twitter, Microsoft)
  • Extensive ecosystem: Cloud Storage, Cloud Functions, Hosting, Analytics, Crashlytics all integrated
  • Mature platform with 10+ years of production use across millions of apps
  • Excellent documentation and largest community (800K+ Stack Overflow questions)
  • Cross-platform SDKs: iOS, Android, Web, Python, Java, C++, Go

Cons

  • Unpredictable costs at scale: can cost 10-50x more than competitors with heavy usage
  • Query limitations requiring complex workarounds for advanced filters and joins
  • Cold start latency of 100-200ms for Cloud Functions impacts real-time responsiveness
C

Convex

+5-3

Pros

  • TypeScript-first design with automatic type safety between backend and frontend (no code generation needed)
  • Predictable fixed monthly pricing ($0-$300+) with unlimited queries and database operations
  • Zero cold starts and <50ms latency on average function calls via persistent workers
  • Real-time sync with automatic optimistic updates built into client libraries (React Hooks)
  • Simpler developer experience: no need to learn Firestore's document model or workaround patterns

Cons

  • Smaller ecosystem: requires integrating third-party Auth0, Clerk, or custom authentication
  • Early-stage platform (founded 2022); less battle-tested in extreme production scenarios
  • Limited to TypeScript/JavaScript (no native Python, Go, or Java SDKs)

Frequently Asked Questions

5 questions

  1. Firebase becomes expensive at approximately 1M+ daily operations. A typical mid-scale app with 100K daily active users performing 10 operations each (1M operations/day) costs ~$180/month on Firebase. The same app costs $20-100/month on Convex depending on tier. Firebase's costs scale linearly with usage; Convex's fixed tiers are more predictable for growing apps.
