React.js vs Ember.js for Web Development - Which Option Wins?

When it comes to software development, there are no best and worst solutions. There are solutions that can either drive benefits to the future project or significantly complicate its creation.

Getting lost in JS frameworks? Let us help you with the right choice. Ask us now!

Framework vs library, Ember vs React

What is the difference between Ember and React? The core difference is the nature of these two technologies. While React.js is a library, that is the set of reusable components software developers can quickly embed, Ember.js is a framework, that is, a more full-fledged tool to use as a skeleton for future app architecture and user interfaces.

Both Ember and React are used for web application development, more precisely, their frontend parts. Still, their use cases and technical feasibility are different. As for Ember vs React comparison in terms of their popularity, React.js is much more popular compared to Ember, according to a JavaScript survey. While React.js shows stable interest year after year, the popularity of Ember decreases significantly.

Nevertheless, both of the JavaScript frameworks can drive significant benefits in the process of application development when used right and intelligently tailored to the project goals. Let’s overview React and Ember.js pros and cons to make a winning choice.

Framework vs library, Ember vs React

Usage trends: React.vs Ember

React.js overview

React.js is one of the most popular libraries for frontend development with JavaScript. Its extensive tooling, efficient debugging, easy testing, and components reusability make this library one of the top choices you can make for your future app. Using React.js can also promise fast development speed, a trouble-free process, and a web app perfectly discovered and indexed by the search engine.

React.js overview

  • React.js significantly streamlines the creation of UI components
  • There are a lot of useful tools and add-ons
  • The code created with React.js is clear and SEO-friendly
  • Testing and debugging is easy with this library
  • React.js promises fast rendering
  • React.js has a wide community and great talent pool to gather your team


  • Learning React.js may not be as easy as it seems at first glance. While some developers say that basic JS skills will be enough to get started with this library, others say handling React.js can be tricky.
  • React. js uses JSX. This is the technology that mixes Javascript with HTML. This feature can have both pros and cons depending on the use case.
  • React.js documentation lacks clarity - and this can be the logical explanation for both of the cons from above.

Business use cases

A lot of globally famous companies use React.js to power their web apps; for example, New York Times, Instagram, and Airbnb - just to name a few. Below are the types of projects React.js is perfectly compatible with.

  • Single Page Application (SPA). When using React.js to create SPAs, the developers can take benefit from the server-side rendering, which is faster compared to the client-side, and make the single page app even more performant and fast-working.
  • Dynamic Web Pages. Virtual DOM (Document Object Model) supported by React. js can be the reason to use it for dynamic content apps. Virtual DOM streamlines the response speed of the app when the user makes even minimalistic changes.
  • eCommerce website or any other website with multi-level UI. React.js can be a winning option to build eCommerce websites and other solutions with heavy architectures and UI because of the component reusability. To put it simply, React allows for creating complex software at a faster pace, saving time and effort.

IT Master Soft case studies with React.js

We like using React.js as a part of our development processes since it makes a lot of things easier. However, most of the recent apps we have created using this tool are DNA-protected, so we can share only some general points which, nevertheless, showcase the opportunities and applicability of React.js pretty well.

  • An application for hiring service workers. The specific feature of this app is the opportunity for those in job search to create video self-presentations and attract more attention from potential employees. This is an example of how React.js can be used to create dynamic content apps. Now, we work on embedding the app with an automated staff management system.
  • We have also created a solution on the verge of eCommerce (this is one of the top industries to use React.js in the development process) and charity. The app allows the users to buy certain goods while the money earned from deals will be redirected to support kids from an orphanage.
  • As one more example, there is a logistic website that connects truck owners with auto owners in need to move the vehicle from a certain location to another. This case study shows how React.js can simplify users’ communication within the app.

Ember.js overview

Ember has been here for ten years already. This is an open-source framework, powered by HTML, CSS, and JavaScript. Creating heavy web apps is the main use-case of the technology, however, some experts suggest the features of Ember can be also tailored to desktop and mobile development in some cases.

Also, Ember becomes less popular and slightly outdated technology year after year, in contrast to Angular.js for example, which is also ten years old but is still loved and respected in the developers’ community.

  • Client-side rendering. While server-side rendering is better for SEO and super-fast user experience, client-side rendering makes sense when it is necessary to streamline web app usage on mobile devices
  • Convention over configuration. To put it simply, using this development paradigm, the developers can make fewer decisions and change the configuration of the element only when they extremely need it. It streamlines the development process and saves effort
  • MVC (Model-View-Controller) architecture which is beneficial for large-size apps since the modifications don't affect the entire system
  • Clear documentation


  • Ember. js is one of the less popular JS frameworks
  • Its community is pretty small
  • Ember.js is heavy and lacks flexibility
  • Learning this framework is mostly difficult

Business use cases

Despite its popularity being decreased recently, Ember.js is still used by prominent projects. For example, take a look at the Groupon website - it is built with Ember as one of the tools in their tech stack.

As for the Ember.js use cases, it performs best when used for large websites - Groupon is a suitable example in this case as well. The developers also choose Ember when they prioritize the stable architecture over the rapid-fast user experience (because of the client-side rendering), and need to embed complex features. This framework can sometimes be an option for Single Page Apps.

So, is Ember better than React? Both Ember and React.js have their pros and cons, and when they are used right, the positive features of each of the technologies are likely to outweigh its limitations. Also, there is one more condition for using both React and Ember successfully - your development team members should be tech-savvy and skilled enough to handle them since these technologies can be challenging to deal with.
