The 7 Best Code Playgrounds to Learn, Share and Experiment

Have you ever come up with an exciting code idea that you want to try out instantly and share with your colleague? You’re not alone.

Code playgrounds let you do just that. They are online platforms that let you quickly run both client and server-side code without the need to set up, configure and own the infrastructure.

All you need to do is create an account and code away!

What is a Code Playground?

Code playgrounds are online platforms that let you build, test and share code with colleagues and the community. These playgrounds are breeding grounds for ideas and offer an easy way to share your ideas with the community.

For example, Codepen, one of the most popular code playgrounds platforms, lets users explore others’ work through the Trending section that lists unique and interesting code samples from developers worldwide.

Generally, code playgrounds are optimized for front-end development, especially HTML and CSS, but you’ll also find server-side code playgrounds.

Apart from sharing your work, you can also use code playgrounds for learning. Beginners can use it to create simple web templates(HTML/CSS) or run their JavaScript. That’s great, considering new learners generally struggle to set up and configure a development environment.

Most code playgrounds are free to use but come with a paid tier offering advanced features. Some of the common code playgrounds features include:

  • Feature-rich web editor(HTML, CSS and JavaScript) supporting auto-complete.
  • Real-time preview window.
  • Support for Sass, Less, HAML, Stylus and other processors.
  • Support popular JavaScript libraries, including Vue.js, Angular, React, etc.
  • Collaborative coding features
  • Fork Github repositories
  • Easy sharing options
  • Code validation and developer console tool

How can Code Playgrounds help you become a better programmer?

Programming is all about practice. The more practice you do, the better you become. Code playgrounds provide the environment for practice, sharing and experimentation. It facilitates an easy way to get up with your project and share it with the world.

Moreover, many code playgrounds have weekly challenges(for example, CodePen). These challenges are unique and let you solve problems, increasing your skills. In short, Code playgrounds provide a seamless way to do coding, especially for beginners.

The 7 Best Code Playgrounds To Play With Code

1. CodePen

CodePen is a top-tier online code playground where you can create front-end Pens and full-blown projects for teams.

CodePen

As for functionality, you can build and test directly from the browser. It offers a neat user interface and real-time results.

Which Code Playground Should you choose?

Choosing a code playground is easy. You must look if the code playground supports the programming language you are working with. If it does, try it out to see its features, such as configurability, shareability and collaborativeness. 

We recommend CodePen as it is a great starting place if you're into web development. It offers an excellent interface, great community and good editor features.

For JavaScript specific-projects, you can go with JSFiddle and JSBin. And, if you're looking for more programming language support, then Replit should get your attention.

For learners, Sololearn is an excellent place to start. For a similar experience but no code playground option, you may also want to check out FreeCodeCamp.

Your search should not stop here. The web is full of options when it comes to code playgrounds. We suggest checking out Dabblet, PLAYCODE, Plunker, Glitch, Liveweaver and ESNextBin.

Finally, remember code playgrounds are for experimenting, sharing your work and collaborating. So, which code playground do you want to try first? Comment below and let us know.
