What is an IDE?

An IDE is a software application that provides all the required tools for software development in a single environment. It facilitates the creation, compilation, debugging, testing, building, and deployment of software applications, streamlining the software development process and ultimately enhancing developer productivity.

Most IDEs are available free of charge, while commercial licenses may be required to access more advanced features. Until recently, most IDEs were desktop applications that users had to download and install on their local machines. They also  required specific hardware and software to run efficiently.

What is a browser-based IDE?

Recently, IDEs have evolved into browser-based or cloud-based IDEs, allowing developers to access them through any web browser. Browser-based IDEs are typically powered by third-party companies and hosted in cloud-computing environments. Users no longer require powerful computers to run these IDEs, eliminating the need for downloading and installing them. 

Browser-based IDEs are excellent tools for facilitating online collaboration, especially when development teams work across multiple locations. However, it's important to note that these IDEs are still evolving, and may have limitations.

Features to consider when choosing a browser-based IDE

With numerous browser-based IDEs available, it is crucial to consider the following essential factors when selecting the most suitable one:

Features of the code editor. Look for code editing features that help increase your coding speed, such as automatic code completion and indentation, syntax highlighting, and code refactoring features. 

Supported languages. Does it support the programming languages you intend to work with? Are there any plugins and extensions available for the specific programming languages you need? 

Debugging support. Check if the IDE has built-in tools for debugging your code with features like breakpoints and step-through debugging.

Testing support. The IDE should support popular testing frameworks for unit testing and other test automation tasks.

Plugins and extensions. The support for using various plugins is crucial for extending the functionality of your software application. Check if the editor supports popular extensions and plugins, such as remote extensions and code formatting extensions.

Pricing. Browser-based IDEs also come with pricing packages. Thoroughly check if the features they offer match your budget and requirements. 

Documentation and support. The IDE should provide instructions on how to use it. Some IDEs automatically walk you through the environment to explain all the required features. Additionally, it’s nice to have online support for troubleshooting issues, tutorials, videos, etc., to learn more about the IDE.

Availability of smart tools. Consider the availability of AI tools to support your development tasks. For example, some AI tools can help debug the code and provide intuitive suggestions to improve it.

Choosinga browser-based IDE vs. a desktop IDE

Browser-based IDEs offer several advantages compared to IDEs set up on local machines. 

Browser-based IDEs eliminate the need to install, set up, and maintain IDEs on local machines

Setting up an IDE on a local machine involves downloading and installing the required dependencies. You must also meet specific hardware and software requirements and other configurations to utilize the software. 

Browser-based IDEs eliminate these tasks, saving time for developers. You don’t need to worry about installing updates or configuring settings when switching between machines. 

Platform independence

Desktop IDEs depend on the platform you are working on. You must set up the corresponding packages whenever you switch between operating systems, such as Windows, macOS, and Linux. On the other hand, browser-based IDEs do not depend on a specific operating system on your machine.

Improves collaboration and code sharing

Browser-based IDEs are great online collaboration and code-sharing tools. Browser-based IDEs would eliminate the need for sophisticated software, hardware, and other dependencies — and are great for remote-working use cases, like live coding interviews and pair programming. 

Scalability and efficiency

Browser-based IDEs leverage cloud infrastructure, providing developers with a scalable environment with ample resources, meaning you can execute, build, and test your code without worrying about scalability and efficiency requirements.

Integration with other tools

Browser-based IDEs support integration with other tools, such as GitHub and project management tools, allowing users to simplify and speed up their development work.

The ability to access the IDE from anywhere

In contrast to desktop IDEs, browser-based IDEs are accessible from anywhere using your accounts — allowing you to use any machine and making it highly convenient for frequent travelers.

(All of these factors can be key in supporting a successful DevOps team)

Limitations of browser-based IDEs

While browser-based IDEs are gaining traction in the industry, they also have some limitations that you should consider before investing in a specific IDE.

Internet connectivity and network issues

Since browser-based IDEs rely on the internet, your work can be interrupted by connection speed drops and various other network issues.

Security and privacy issues

These IDEs are hosted in cloud-based environments and operate on web browsers. If the IDE hosting site lacks sufficient security and privacy features, your systems and data can be vulnerable to unauthorized access

Check if the browser has security features like updated SSL certificates and secure login before using them.

Browser compatibility issues

Some browser-based IDEs may not support every web browser and can have issues with browser updates. Therefore, it is critical to ensure you use a compatible web browser and prepare to switch to an alternative browser if any compatibility issues arise due to updates.

Limitations in customization and third-party integrations and extensions

Not all browser-based IDEs support the required third-party integrations, extensions and libraries, and users will have to limit customizations for their software applications.
