The short version

  • Each has a real cost: Eclipse high memory consumption and CPU usage, especially with multiple plugins installed; 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: Eclipse covers Java development environment, React Native covers Renders to native components.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Eclipse

  • High memory consumption and CPU usage, especially with multiple plugins installed
  • Slow startup times and performance degradation with large projects or many open editors
  • Requires configuration of eclipse.ini file to optimize heap sizes for adequate performance
  • User interface considered outdated compared to modern IDE alternatives
  • User base fell from 39% of Java developers in 2024 to 28% in 2025, indicating market decline

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

Eclipse: How much does Eclipse IDE cost?

Eclipse IDE is completely free and open-source, released under the Eclipse Public License 2.0.

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.

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.

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.
