5 Best Open Source Frameworks For Developers in 2021

A framework provides you the best solution for developing well-structured, maintainable, and upgradeable software. It saves a lot of time by re-using generic modules and libraries in order to focus on the other areas. Applications developed using a framework are interoperable with market standards.

But, there’s always been confusing for many beginners to select the right framework. There are many frameworks for developing the same type of application. Without proper knowledge and research, you may end up learning a framework that is no longer useful or required for modern applications. That is the main reason behind this article. Here, I’m going to mention 5 best open source frameworks for developing modern applications.

5 Best Open Source Frameworks For Developers

There was a time when Javascript used to be considered as a client-side scripting language for web applications. It used to be embedded in an HTML page and run by a JavaScript engine in the web browser.

The node.js framework was created with the idea of unifying web application development around a single programming language, rather than different languages for server side and client side script. So it created JavaScript run-time environment that executes JavaScript code on the server-side. It is now one of the 5 best modern javaScript frameworks for Web and App development.

Node.js has an event-driven architecture capable of asynchronous I/O. It aims to optimize throughput and scalability in web applications, chat applications, games, and other software.

Benefits:

  • Node.js is a Free and Open Source framework.
  • It is suitable for developing web, mobile, and browser-based applications.
  • It runs on All major platforms
  • Node.js uses JavaScript on the server.
  • Used by many big companies like Microsoft, PayPal, IBM, Netflix, and Linkedin, etc.

3. Ruby on Rails

It facilitates the use of web standards such as JSON or XML for data transfer, and HTML, CSS, and JavaScript for display and user interfacing.

It encourages the use of popular software engineering patterns and paradigms i.e. convention over configuration (CoC), doesn’t repeat yourself (DRY), and the active record pattern.

Ionic uses native SDKs to bring the UI standards and device features of native apps together with the full power and flexibility of the open web. It uses Cordova or PhoneGap to deploy natively or runs in the browser as a Progressive Web App.

There are over 120 native device features like Bluetooth, HealthKit, Finger Print Auth, and more with Cordova/PhoneGap plugins and TypeScript extensions.

Benefits:

  • Free, open-source, and fully cross-platform.
  • First-class documentation and a wide community.
  • Requires knowledge of HTML 5, JS, and CSS only.

Benefits:

  • It’s suitable for Machine Learning, Deep Learning, or AI development
  • Open Source, Free, and Widely Compatible.
  • Used by Google, Nvidia, AMD, Uber, and Intel, etc.

Note: Like any other top-list article on the internet, this is an opinion. The frameworks are ranked on various parameters like Update time, Community support, Ease of use, compatibility, and acceptability, etc. It’s ok if you do not find your favorite frameworks in this list.

    • Node.js is not a language, it’s a framework that is built on the top of javascript language. Django is a web framework which can be used sometimes to make a CMS but it’s NOT a CMS!. The difference is quite huge. I’ve done my best research. I also request you to do the same before creating misunderstanding among other readers. Welcome! I’m glad you find it helpful.
