According to several studies, there are about 18.2 million software developers worldwide and that is expected to rise up to 26.4 million by 2019 end, with a 45% increase. So there is no doubt that web and Android development is one of the most popular jobs in the world today.

To become an expert developer in this cut-throat competition you need to master the programming, development process, and take full advantage of the best tools out there. In fact, learning how to use these tools is the first crucial step you have to take in your web and Android development journey.

If you are a beginner or pro developer in the Android and web development space you need a rich source of the best open-source toolkit in your development workflow to build better and dynamic websites as well as Android applications.

So without any more preamble let’s have a look at 2019’s 11 top web and Android development tools that are open-source and will grow your development efficiency exponentially.


AngularJS is an open-source free JavaScript framework to build dynamic front-end web applications. Due to its powerful features, it has become one of the favorite tools among web developers worldwide. AngularJS was developed by Google and it is mostly used for building single page web applications.

It allows you to use HTML as your template language and you can extend the HTML syntax to express your web application components more precisely. Its data binding and dependency injection system eliminate most of the code writing part and you can access all the features from your browser.

MVC Framework - This framework is based on the concept of Model View Control (MVC) architecture and it helps you build the client-side web applications. You do not need to write extra code to fit all the elements together. It allows you to create all the MVC elements separately and it automatically combines them by using AngularJS Framework.

Data Binding - You don’t have to write special code to bind data; it automatically synchronizes data between model and view components.

Less coding - You don’t need to write a different set of code for different devices for running the application. A single code will do the work for you and that can be used for various platforms.

Unit testing - The code is divided into smaller units and that helps you to easily detect any mistakes in each line of the code. It has an in-built dependency injection system through which mock units are injected and tested to see whether the output is producing expected data or not.


Node.js is an open-source and free JavaScript for developing server-side applications. Node.js is built on Chrome's V8 JavaScript engine to build scalable network applications. It uses event-driven, non-blocking I/O model that makes it lightweight as well as efficient.

Most of the basic modules of Node.js are written in javascript and it also provides a rich library of various javascript modules that simplifies the web application development process.

Fast execution - As Node.js is built on Chrome's V8 javascript engine its library works very fast in executing different codes.

Highly scalable - Its event mechanism helps the server to respond in a non-blocking way that makes it highly scalable.

Asynchronous and Event-driven - Node.js library involves asynchronous APIs that means the server never waits for an API to return data, instead it moves to the next API after calling it. Its notification mechanism of events helps the server to receive a response from the previous API call.

No Buffering - Node.js applications never buffer any data, as it speeds up the whole process by giving output data in smaller chunks.

Single threaded - Node.js applications use a single-threaded model with event looping.

Android Studio

Android Studio is another open-source tool that contains all the features you need to build an Android app. This tool is also known as the official integrated development environment (IDE) for Google’s Android operating system.

I'm just now moving from getting my tool list functional to having 150ish downloads on a project. What should I use instead of Bower? It's the only one I wasn't already aware of before
