The short version

  • Each has a real cost: Firebase spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes; React Native the JavaScript bridge has historically been a bottleneck for animation-heavy and list-heavy screens, though the New Architecture addresses much of it
  • They diverge on capability: Firebase covers Real-time Database, React Native covers Renders to native components.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Firebase

  • Spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes
  • Spark plan restricts to 100 concurrent database connections
  • Spark plan limits Firebase Studio to 3 workspaces maximum
  • Document size capped at 1 MiB per document
  • Transaction time limited to 270 seconds with 60-second idle expiration
  • Maximum 100 databases per project (increase requires support request)

React Native

  • The JavaScript bridge has historically been a bottleneck for animation-heavy and list-heavy screens, though the New Architecture addresses much of it
  • Upgrading between versions has a reputation for being painful, particularly with many native dependencies
  • Anything the framework does not wrap requires native code in Swift or Kotlin, so a purely JavaScript team can still get stuck
  • Because it renders to real platform components, small behavioural differences between iOS and Android surface in your code rather than being hidden

Answered from the vendors’ own pages

Firebase: What are Firebase's free tier limits?

Firebase Spark plan includes no-cost daily-refreshing quotas: Cloud Firestore up to 1 GB storage with 20K writes and 50K reads per day; Cloud Functions up to 2M invocations monthly; Cloud Storage 5 GB-months with 100 GB downloads monthly; Hosting 10 GB storage and 360 MB daily data transfer; Realtime Database up to 1 GB storage. No payment method required.

Source
React Native: Is React Native free?

Yes. React Native is open source from Meta with no licence fee, and it is free for commercial use.

Firebase: How much does Firebase Blaze plan cost?

Firebase Blaze is pay-as-you-go beyond free tier limits. Pricing includes Cloud Firestore storage at $5/GB after 1 GB; Cloud Functions $0.40 per million invocations beyond 2M monthly; Cloud Storage $0.026/GB beyond 5 GB; Hosting $0.15/GB beyond 360 MB daily. New eligible customers receive $300 free credit.

Source
React Native: Does React Native produce a real native app?

Yes. JavaScript primitives render to the platform’s own UI components using the same native APIs a Swift or Kotlin app would call, rather than to a web view.

Firebase: Which Firebase services are always free regardless of tier?

A/B Testing, Analytics, App Check, Cloud Messaging, and Crashlytics are offered at no cost on both Spark and Blaze plans, with no usage limits stated.

Source
React Native: Which well-known apps use React Native?

Meta cites Facebook, Microsoft Office, Teams and Outlook, Amazon Shopping, Discord, Coinbase and Tesla among thousands of apps built with it.

React Native: Should I use Expo or plain React Native?

Expo handles builds, updates and native configuration for you and is the recommended starting point. Plain React Native gives full control of the native projects, which matters when you need native code the managed workflow does not cover.
