The short version

  • Each has a real cost: Eclipse high memory consumption and CPU usage, especially with multiple plugins installed; React jSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript
  • They diverge on capability: Eclipse covers Java development environment, React covers Component-based architecture.
  • Prices and features above were last checked on 30 August 2026.

Both are used for web application development, on those jobs the choice comes down to price and fit rather than capability.

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  • User interface considered outdated compared to modern IDE alternatives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

  • JSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript
  • Routing and state management are separate dependencies, not included in core library
  • Configuration complexity for advanced features like server-side rendering without a meta-framework
  • Requires choosing and configuring build tools and development environment setup

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: Is React free to use commercially?

Yes. React is distributed under the MIT open-source license, which permits free usage for both personal and commercial projects without licensing fees or restrictions.

Source
React: Does React support TypeScript?

Yes. React works seamlessly with TypeScript for type-safe component development. TypeScript provides static type checking for React components, props, and state, improving code reliability and developer experience.

Source
React: Do I need a build step to use React?

If you use JSX, yes. JSX requires transpilation by a build tool like Webpack and Babel before browsers can execute it. However, React can be used without JSX by calling React.createElement directly, which does not require a build step.

Source
React: Can I build offline-capable applications with React?

Yes. React supports building Progressive Web Apps (PWAs) with service workers and IndexedDB for offline functionality. Create React App includes service worker setup, though it must be manually enabled for production use.
