The short version
- Each has a real cost: 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; Firebase spark plan limited to 1 GiB storage, 50,000 daily reads, 20,000 daily writes
- They diverge on capability: React Native covers Renders to native components, Firebase covers Real-time Database.
Where they differ
Only the attributes on which React Native and Firebase actually diverge.
| Attribute | React Native | Firebase |
|---|---|---|
| Pricing model | Open source, no licence fee | freemium |
| Platforms | iOS, Android, Windows, macOS, Web | iOS, Android, Web, Flutter, C++, Unity |
| Founded | Unknown | 1998 |
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated), category (Mobile Development).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
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)

Which should you pick?
Choose React Native if
- You need renders to native components.
- You want to start without paying.
- You work on iOS, Android, Windows, macOS, Web.
- You also want react programming model.
Choose Firebase if
- You need real-time database.
- You want to start without paying.
- You work on iOS, Android, Web, Flutter, C++, Unity.
- You also want rest api.
Questions people ask
- Is React Native or Firebase better?
- Neither clearly leads. React Native starts at Free and Firebase at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, React Native or Firebase?
- React Native starts at Free and Firebase at Free.
- Does React Native or Firebase run on more platforms?
- React Native runs on iOS, Android, Windows, macOS, Web. Firebase runs on iOS, Android, Web, Flutter, C++, Unity.
- Can I use React Native for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is React Native best used for?
- React Native is most often used for teams with react experience on the web extending into mobile, apps that should feel like the platform rather than look identical across both, adding a mobile client to a product whose engineers already write javascript, reusing business logic between web and mobile codebases. Of those, teams with react experience on the web extending into mobile and apps that should feel like the platform rather than look identical across both are not what Firebase is typically brought in for.
- What can React Native do that Firebase cannot?
- React Native covers Renders to native components, React programming model, Native modules, Fast Refresh. Firebase covers Real-time Database, REST API, Authentication, Google Cloud.
Answered from the vendors’ own pages
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: 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.
SourceReact 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: 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.
SourceReact 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.
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.
SourceReact 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.
