Expo vs React Native CLI in 2026: Which One Should You Choose?

By Ahsan Hafeez · 2026-11-05

If you're starting a React Native project in 2026, the first decision you'll face is: Expo or bare React Native CLI? Having shipped production apps with both, here's my honest breakdown.

What Is Expo?

Expo is a platform built on top of React Native that provides a managed workflow, a set of well-tested libraries (the Expo SDK), and cloud build services (EAS). It abstracts away most native configuration so you can focus on JavaScript/TypeScript.

# Create a new Expo project
npx create-expo-app@latest my-app
cd my-app
npx expo start

That's it. No Xcode, no Android Studio — scan the QR code with Expo Go on your phone and you're running.

What Is React Native CLI?

The "bare" or "vanilla" React Native setup gives you direct access to the ios/ and android/ directories. You manage native dependencies, Xcode and Gradle configs, and builds yourself.

# Create a bare React Native project
npx @react-native-community/cli init MyApp
cd MyApp
npx react-native run-ios

You need Xcode (macOS) and Android Studio installed and configured before this works.

Setup & Developer Experience

File-based routingYes (Expo Router)No (use React Navigation)

Verdict: Expo wins on DX by a wide margin. The onboarding experience is dramatically faster, especially for teams with developers who don't have native iOS/Android experience.

Native Module Support

This used to be Expo's biggest weakness. Not anymore.

Expo in 2026

  • Expo Modules API lets you write native modules in Swift and Kotlin with a clean, type-safe interface — no more Objective-C bridging headers
  • Config plugins let you modify native project files without ejecting
  • Prebuild (npx expo prebuild) generates native projects when you need them
  • Most popular libraries (camera, maps, notifications, in-app purchases) have Expo-compatible versions
// expo-module.config.json — creating a custom native module
{
  "platforms": ["ios", "android"],
  "ios": { "modules": ["MyModule"] },
  "android": { "modules": ["MyModule"] }
}

React Native CLI

  • Full native access from day one
  • Any CocoaPod or Gradle dependency works
  • More boilerplate but zero abstraction layer
  • You manage autolinking and pod installs yourself

Verdict: If you need obscure native SDKs (custom Bluetooth protocols, hardware integrations, legacy SDKs with only Objective-C APIs), bare CLI gives you fewer surprises. For everything else, Expo's module system handles it.

Build & Deployment

Expo (EAS Build)

# Build for iOS (cloud)
eas build --platform ios --profile production

# Submit to App Store
eas submit --platform ios

EAS Build compiles your app in the cloud. You don't need a Mac to build for iOS (though you need an Apple Developer account). Builds are queued, and free-tier wait times can be 15-30 minutes.

React Native CLI

# iOS — open Xcode and hit Build
cd ios && pod install && cd ..
npx react-native run-ios --configuration Release

# Android
cd android && ./gradlew assembleRelease

You manage signing, provisioning profiles, keystores, and Fastlane or manual uploads yourself.

Verdict: EAS is a huge time-saver for teams. But if you already have CI/CD pipelines with Fastlane or Bitrise, bare CLI integrates into those without vendor lock-in.

Performance

In 2026, there's no measurable performance difference between Expo and bare React Native for the vast majority of apps. Both use:

  • Hermes as the default JS engine
  • The New Architecture (Fabric + TurboModules) — enabled by default since RN 0.76
  • The same bridge (or bridgeless) layer

The Expo runtime adds ~2-3 MB to your bundle due to included SDK modules, but tree-shaking with npx expo export has gotten significantly better.

Verdict: Performance is a tie. The engine and architecture are identical. Bundle size difference is negligible.

When to Use Expo

  • Startups and MVPs — ship faster, iterate faster
  • Solo developers — less infrastructure to manage
  • Teams without native devs — Expo abstracts the hard parts
  • Apps that use common native features — camera, push notifications, maps, auth, payments
  • Projects that need OTA updates — EAS Update is built-in

When to Use React Native CLI

  • Brownfield apps — integrating RN into an existing native app
  • Heavy native SDK dependencies — AR frameworks, custom hardware, legacy SDKs
  • Existing CI/CD with Fastlane — you already have a build pipeline
  • Monorepos with custom native code across packages — easier to manage linking
  • Apps requiring very specific native configurations — custom app extensions, watchOS targets

Migrating Between Them

Expo → Bare

npx expo prebuild

This generates the ios/ and android/ directories. You keep using Expo libraries but manage native projects yourself. This is called a "bare workflow with Expo modules."

Bare → Expo

npx install-expo-modules@latest

This installs the Expo runtime into an existing bare project. You can then gradually adopt Expo libraries and EAS Build.

My Recommendation

Start with Expo unless you have a specific reason not to. The "specific reason" list has gotten shorter every year. In 2022, I'd recommend CLI for any app needing push notifications or in-app purchases. In 2026, Expo handles all of that.

The escape hatch (expo prebuild) means you're never truly locked in. If you hit a wall, you eject to bare and keep all your code.

For the projects I've worked on — N3xus FieldOS (monorepo with web + mobile), Keystone (complex integrations), Lucky Cement (enterprise ERP) — I'd choose Expo for all of them if starting today. The productivity gains from EAS Build and Expo Router alone justify it.

FAQ

Can I use Expo in a monorepo?

Yes. Expo supports Yarn workspaces and pnpm workspaces. EAS Build handles monorepo builds natively.

Is Expo free?

Expo is open source and free. EAS Build has a free tier (limited builds/month) and paid plans for teams.

Does Expo support the New Architecture?

Yes, since SDK 51. Both Fabric and TurboModules work with Expo modules.

Summary

Expo and React Native CLI both produce the same native app under the hood — same Hermes engine, same New Architecture, same performance. The difference is developer experience. Expo gives you managed builds (EAS), file-based routing (Expo Router), OTA updates, and zero native toolchain setup. React Native CLI gives you full native control from day one — ideal for brownfield apps, custom hardware integrations, and teams with existing CI/CD pipelines. In 2026, Expo covers 95% of use cases, and expo prebuild lets you eject whenever needed. Start with Expo unless you have a specific reason not to.

Interview Questions & Answers

Q1: What is the difference between Expo and React Native CLI?

A: Expo is a platform built on top of React Native that provides a managed workflow, pre-configured libraries (Expo SDK), cloud build services (EAS Build), and abstracts away native configuration. React Native CLI gives you direct access to ios/ and android/ directories with full native control. Both produce the same native app — the difference is in developer experience and workflow.

Q2: Can you use native modules with Expo?

A: Yes. Expo provides the Expo Modules API for writing custom native modules in Swift and Kotlin. Config plugins let you modify native project files without ejecting. For cases needing full native access, npx expo prebuild generates native projects. Most popular libraries (camera, maps, notifications, payments) have Expo-compatible versions.

Q3: When would you choose React Native CLI over Expo?

A: Choose CLI for brownfield apps (integrating RN into existing native apps), projects requiring obscure native SDKs (custom Bluetooth protocols, legacy Objective-C-only SDKs), teams with existing Fastlane/Bitrise CI/CD pipelines, and monorepos with complex native code sharing across packages.

Q4: Is there a performance difference between Expo and React Native CLI?

A: No measurable difference in 2026. Both use Hermes as the default JS engine, the New Architecture (Fabric + TurboModules) enabled by default since RN 0.76, and the same bridge/bridgeless layer. Expo adds ~2-3 MB to bundle size from SDK modules, but tree-shaking has significantly improved.

Q5: How do you migrate from Expo to bare React Native?

A: Run npx expo prebuild to generate ios/ and android/ directories. This creates a "bare workflow with Expo modules" — you keep using Expo libraries but manage native projects yourself. For the reverse (bare → Expo), run npx install-expo-modules@latest.

Q6: What is EAS Build and how does it compare to local builds?

A: EAS (Expo Application Services) Build compiles your app in the cloud. You don't need a Mac to build for iOS (just an Apple Developer account). It handles signing, provisioning profiles, and app store submission. Local CLI builds require Xcode/Android Studio installed, manual signing config, and Fastlane for automation.

Q7: What is Expo Router and how is it different from React Navigation?

A: Expo Router is a file-based routing system built on top of React Navigation. You create routes by adding files to the app/ directory — similar to Next.js pages. React Navigation requires manual route configuration. Expo Router also supports deep linking, typed routes, and server-side rendering preparation out of the box.

Q8: Can Expo apps be used in a monorepo setup?

A: Yes. Expo supports Yarn workspaces and pnpm workspaces. EAS Build handles monorepo builds natively, detecting workspace dependencies automatically. Metro's symlink support (since RN 0.72) eliminated most previous monorepo workarounds.

Q9: What is expo prebuild and when would you use it?

A: expo prebuild generates the native ios/ and android/ directories from your Expo config. Use it when you need to add a native dependency that doesn't have an Expo config plugin, debug native crash logs directly, customize native project settings beyond what config plugins offer, or integrate with native-only SDKs.

Q10: How does Over-The-Air (OTA) update work in Expo?

A: EAS Update allows you to push JavaScript and asset changes directly to users without going through the App Store/Play Store review process. It works by updating the JS bundle that the app downloads on launch. It's built into Expo and requires minimal setup. For bare CLI, you'd use Microsoft CodePush or a custom solution.
