    The term IDE stands for integrated development environment. It is software that combines all the necessary developer tools in a single graphical user interface. In other words, it is a computer application that facilitates the development of applications by bringing all the necessary developer tools under one roof. This blog post will focus on the concept of online IDE.

    The basic developer tools that any IDE consists of are a source code editor, local build automation, and debugger. Since all these tools are available in a single platform, programmers do not need to install and configure them separately on their devices. Also, developers do not need to switch between different tools while developing applications. Well, offline IDEs require you to install them on your computer system, which consumes a lot of space.

    Also, it becomes pretty challenging to transfer the code, which is written in an offline IDE, to multiple systems. To make your code accessible from anywhere, online IDEs come in handy. Also, you do not need to install and configure online IDEs on your local system. This article will make you familiar with some popular and widely used online IDEs. Also, it will help you understand what exactly an online IDE is, along with its advantages and disadvantages. So, let us get started!

    What is an Online IDE?

    An online IDE, also known as a web IDE or a cloud IDE, is a browser-based programming environment that combines the necessary developer tools and works within your browser. It is a web-based integrated development environment that you can access from various browsers, including Google Chrome, Safari, Firefox, and Microsoft Edge. Therefore, for using a web IDE, you just need a compatible browser and a reliable internet connection. You can write, compile, debug, and save your code and access it anywhere from any device. However, online IDEs, as of yet, do not provide all the features that traditional or offline IDEs offer.

    Advantages of Online IDEs

    • Access code anywhere from any device with a browser and an active internet connection.
    • You do not need to install and configure an IDE on your local system.
    • Work on any device.
    • Not prone to configuration drift.
    • Since all the information is stored in the cloud, there are no hardware limitations.

    Disadvantages of Online IDEs

    • Code is available only when there is an internet connection.
    • You cannot customize your development environment.
    • Many online IDEs lack important features that offline IDEs offer. They are more powerful than text editors but have limited features compared to offline IDEs.
