What Tech Stack Does JSBin Use?

Understanding the Tech Stack of JSBin

JSBin is an open-source collaborative web development debugging tool. It was built by Remy Sharp and is completely open source.

What is JSBin?

JSBin is a web application specifically designed to help JavaScript and CSS developers test snippets of code, within some context, and debug the code collaboratively.

Key Features of JSBin

  • Real-time code writing and saving
  • Real-time full preview rendering
  • Support for processors like coffee-script, LESS, Markdown, and Jade
  • Debugging of remote Ajax calls

The Tech Stack Behind JSBin

JSBin is written in JavaScript. The source code of JSBin is available on GitHub and the jsbin module is available for Node.js.

The Evolution of JSBin

  1. Version 1 of JSBin was developed in 2008.
  2. Version 2 was rewritten from the ground up and is completely open source.

Advanced Features of JSBin  

JSBin offers several advanced features that set it apart from other online code editors. One of these is its support for modular units. This feature allows developers to organize their code into separate, reusable modules, making it easier to manage and maintain large codebases.

JSBin also provides advanced debugging tools. These tools allow developers to step through their code line by line, inspect variables, and understand the flow of execution. This can be incredibly helpful in identifying and fixing bugs in the code.

Here are some examples of how these features can be used:

  • Modular Units: Suppose you’re building a complex web application. You can organize your JavaScript code into separate modules based on functionality. For example, you might have one module for handling user authentication, another for managing the application’s state, and so on.

  • Advanced Debugging Tools: If you’re trying to track down a tricky bug in your JavaScript code, JSBin’s advanced debugging tools can be a lifesaver. You can set breakpoints in your code, step through the execution line by line, and inspect the values of variables at each step.

Comparison with Other Tools

There are several other tools available for debugging and testing JavaScript and CSS, such as CodePen, JSFiddle, and Glitch. Each of these tools has its own strengths and weaknesses.

For example, CodePen is known for its strong community and extensive collection of user-created ‘Pens’, while JSFiddle is appreciated for its simplicity and ease of use. Glitch, on the other hand, stands out for its collaborative features, allowing multiple developers to work on a project simultaneously.

However, JSBin holds its own against these competitors with its robust feature set, including support for modular units and advanced debugging tools.

Practical Examples of Using JSBin

JSBin can be used in a variety of practical scenarios. For instance, it’s an excellent tool for creating prototypes of web applications. You can quickly write HTML, CSS, and JavaScript code in JSBin’s editor, see the result in real-time in the output pane, and share the bin’s URL with others to get feedback.

JSBin is also great for testing interactions between JavaScript and CSS. For example, you might use JSBin to experiment with different CSS animations triggered by JavaScript events.

In conclusion, whether you’re a seasoned developer or just starting out with web development, JSBin offers a powerful set of features that can help you write better code more efficiently.


In conclusion, **JSBin** uses a tech stack that is primarily based on **JavaScript** and **Node.js**. Its open-source nature allows for continuous development and improvement.
