CodePen vs JSFiddle: What are the differences?


CodePen and JSFiddle are two popular online code editors that allow users to write HTML, CSS, and JavaScript code and see the live output in real-time. While both platforms offer similar functionalities, there are some key differences between them. In this Markdown code, we will discuss six specific differences between CodePen and JSFiddle.

  1. Collaborative Editing: CodePen allows multiple users to collaborate on the same project simultaneously, making it easy for teams to work together. On the other hand, JSFiddle only supports individual editing, limiting it to single-user projects.

  2. Editor Layout: CodePen offers a three-pane layout where users can simultaneously view their code, the live output, and the console output. This layout allows for a more comprehensive coding experience. In contrast, JSFiddle utilizes a two-pane layout, providing users with the code view and live view side by side.

  3. Supported Libraries and Frameworks: CodePen supports a wide range of libraries and frameworks, including popular ones like Bootstrap, React, and Vue.js. JSFiddle, on the other hand, has a limited library support and may not provide the latest versions of the libraries.

  4. Integration with External Resources: CodePen provides seamless integration with external resources such as web fonts, CSS preprocessors, and JavaScript frameworks. JSFiddle, though it has similar functionality, might not offer as many options for integrating external resources.

  5. Code Privacy: CodePen allows users to keep their projects private, accessible only to those who have the direct link or are added as collaborators. JSFiddle, on the other hand, does not provide a built-in option for making projects private. All projects created in JSFiddle are accessible to the public.

  6. Community and Social Features: CodePen has a larger user community and provides various social features such as comments, love/reacts, and the ability to follow other users. JSFiddle has a smaller community and lacks some of the advanced social features present in CodePen.

In Summary, CodePen offers collaborative editing, a three-pane layout, extensive library support, integration with external resources, code privacy options, and a larger user community compared to JSFiddle.
