Ten Popular Open Source Tools for Web Developers


Web application development is a dynamic and challenging field. Here’s a quick look at ten cutting-edge Web application development tools that can make the job of developers a lot easier.

The best as well as, perhaps, the worst part of being a Web developer is that Web applications are constantly changing, be it in terms of the complexity of the application or the technology used. While this makes the task of Web developers quite exciting, it also means that they must always be up-to-date on new techniques or programming languages, should easily adapt to changes, and also be willing and eager to accept new challenges. This may include various tasks such as:

  • Changing the existing frameworks to meet several business requirements
  • Testing a Web application to identify technical glitches
  • Scaling and optimising a website to perform better with the given back-end infrastructure
  • Improve the user experience for the website and make it more user friendly
  • Fulfil different user requirements

According to a recent ‘Future of Open Source’ survey from Black Duck Software, 65 per cent of organisations use different open source software. Further, open source Web development tools are actually the third-most common type of open source software being used by businesses (just after operating systems and databases) nowadays. Lou Shipley, president and CEO of Black Duck, notes in one of the reports that open source is actually the way applications are being developed today. One of the major reasons for this is that open source software is available free of cost. Also, there is a large community base associated with different open source tools, which makes their maintenance and optimisation quite easy.

At a time when websites are getting more complex, developers need more advanced and sophisticated Web development tools for their tasks. There are already plenty of such open source tools available in the market and advanced options are constantly being introduced. A proper understanding of these Web application development tools will help developers complete their tasks better and faster. So here’s a quick look at some popular open source tools or frameworks for Web app development.


AngularJS is widely used to build different dynamic Web apps. Basically a JavaScript framework, it is mostly used to build single page Web apps. It also helps with the data binding and filters using HTML attributes. It supports DOM (Data Object Model) handling, forms and form validation. This open source tool was developed by Brat Tech LLC under an MIT licence and later made open source. First released in 2009, AngularJS is now maintained by Google.
