The short version

  • Each has a real cost: EAS Build iOS builds run on macOS workers charged at a much higher rate than Linux, so the invoice is dominated by the platform you have least ability to move off.; Flutter dart is used almost nowhere else, so the language itself is a hiring and learning cost
  • They diverge on capability: EAS Build covers Hosted macOS and Linux workers, Flutter covers Single codebase, many targets.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

EAS Build

  • iOS builds run on macOS workers charged at a much higher rate than Linux, so the invoice is dominated by the platform you have least ability to move off.
  • Lower tiers queue behind higher paying customers, which is invisible until a hotfix build waits in a queue while an incident is running.
  • It is specific to React Native and Expo, so a company with a native Swift or Kotlin codebase alongside gets no benefit and needs a second build system anyway.
  • Deep use of managed credentials and over the air updates makes leaving harder than swapping a continuous integration provider, because the release process itself has been built around the service.
  • Build failures happen on infrastructure you cannot inspect, and reproducing an environment specific failure locally is harder than with a self hosted runner you can log into.

Flutter

  • Dart is used almost nowhere else, so the language itself is a hiring and learning cost
  • Because Flutter draws its own widgets, apps can feel subtly unlike the platform unless deliberately styled per-platform
  • Binary sizes are larger than equivalent native apps because the engine ships with the app
  • Access to a brand-new platform API waits on a plugin, or on writing platform channel code yourself

  • Paid tiers$undefined/month
    • Monthly subscription buying build concurrency and included minutes, with overage per minute above them
    • macOS minutes cost several times Linux minutes, so iOS pipelines dominate the bill

Answered from the vendors’ own pages

EAS Build: Does it work without the Expo managed workflow?

Yes. Bare React Native projects build fine, which is a common misconception that costs teams an unnecessary evaluation.

Flutter: Is Flutter free?

Yes. Flutter is open source with no licence fee. The framework is under a Creative Commons Attribution 4.0 licence and its code samples under the 3-Clause BSD licence.

EAS Build: Why not just use GitHub Actions macOS runners?

You can, and it is often cheaper. You then own credential management and the Xcode version treadmill, which is the work EAS is actually selling.

Flutter: What language does Flutter use?

Dart, a language Google designed for fast startup and ahead-of-time compilation to native code.

EAS Build: Can JavaScript updates skip App Store review?

Yes through EAS Update, within Apple's rules about not changing the app's purpose. Native changes still require a store submission.

Flutter: Can Flutter build for more than mobile?

Yes. The same codebase targets iOS, Android, web, Windows, macOS, Linux and embedded devices, though mobile remains the most mature target.

Flutter: How is Flutter different from React Native?

Flutter draws its own widgets with its own engine, so the result is pixel-identical across platforms. React Native renders to the real native components of each platform. Flutter uses Dart; React Native uses JavaScript and React.
