Over the past two years, several coded playgrounds have appeared, here are the best ones for you

Whether you are a beginner programmer or an expert developer, code playgrounds are useful for sharing and learning with others. These are web applications that allow real-time editing and previewing of client-side codes: HTML, CSS, and JavaScript. Code playgrounds are online services where you can write, compile (or run), and share code with others. They also give you the ability to branch off and play with other people’s codes. With this, they can edit the code online, preview the work at every step, debug the error, and test the snippets cases. Developers can also share the code and see the changes they have made to the code. On that note, this article lists the top 10 code playgrounds that every web developer should try.

JS Trash

It provides an environment for building apps and helps in testing HTML and CSS snippets. It allows you to edit the code and also debug the code. Once you’ve finalized the code, you can send it to a peer for review.

JSFiddle

jsFiddle is a shell editor that makes it easy to write JavaScript code by creating a custom environment based on popular JS frameworks. You can select the framework & version of your choice (MooTools, jQuery, Dojo, Prototype, YUI, Glow, Vanilla). Also, if there is, you can add an add-on framework like jQuery UI or MooTools. A cool feature is the ability to save and share the created code with a unique generated URL. Optionally, jsFiddle also has an embed feature. It’s an almost perfect platform to try out and share your JavaScript code without the need for a website.

Dabblet

Dabblet is an interactive playground for quickly testing CSS and HTML code snippets. It uses -a format with no prefix so you don’t have to add prefixes in your CSS code. You can save your work to Github Highlights, embed it in other websites, and share it with others. It currently only supports modern versions of Chrome, Safari, and Firefox. All code displayed belongs to the poster and no license is applied. Dabblet itself is open source software and is distributed under an NPOSL-3.0 license.

CodePen

CodePen is a playground for the front end of the web. It’s a question of inspiration, education and sharing. The service highlights popular demos (“Pens”) and offers advanced features such as sharing and embedding. CodePen is ideal for creating a reduced test case to demonstrate and understand a bug.

CSSDesk

CSSDesk is an online CSS sandbox. It allows users to quickly test CSS snippets and watch the result appear live. There are line numbers and syntax highlighting appear in the text box as you type. One of the greatest things is that it allows users to share their code with others.

Google’s Code Playground

Google’s Code Playground is a web tool that allows web developers to try out all the APIs provided by Google, modify the code and see the results. Google’s Code Playground lets you play without opening an external editor, and all APIs are loaded for you in the Choose an API box

Editor

Editr is an HTML, CSS and JavaScript playground that you can host on your server. It is based on the ACE editor. It’s super easy to set up. It supports multiple instances on a single page. Configurations are available via JS object or HTML attributes. Editr supports 3 layout views: horizontal, vertical and simple. The first two are for live editing. The third is for presentation. Editr is under the MIT license.

live wave

Liveweave is an HTML5, CSS3, and JavaScript playground and real-time editor for web designers and developers. It’s a great tool for testing, practicing, and sharing your creations. It has resizable panels so you can write your code (or weave, as we call it) the way you want. Liveweave also integrates pop-up code hints for HTML5 and CSS3 tags/attributes, which makes life much easier.

D3 playground

The D3.js playground is designed to allow you to play with the D3.js library interactively. Every change made (which results in an invalid code) affects the playing field in real time. Because CSS is such an important part of visualizations, you can also edit CSS live.

HTML5 playground

HTML5 Playground includes a library of code snippets that you can explore to see HTML5 in action. They include some basic starter examples, such as using the HTML5 Doctype and the audio tag (which is nonetheless a good demonstration of playback features in a compatible browser). There’s an interactive form, including HTML5 elements like range and date entries and automated email and website validation.
