If you are developer and looking for best code playgrounds to play with code then you are at right place. In this article I have gathered 10 of the best free code playgrounds and sandboxing tools for testing, debugging and sharing your code snippets. If you are aware of any other nifty code playgrounds, do let us know by commenting in comment section.
CodePen is a playground for the front end side of the web. It’s all about inspiration, education, and sharing. The service highlights popular demonstrations (“Pens”) and offers advanced functionality such as sharing and embedding. Need to build a reduced test case to demonstrate and figure out a bug? CodePen is great for that. Want to show off your latest creation and get feedback from your peers? CodePen is great for that.
CSSDesk is an Online CSS Sandbox. It allows people to quickly test snippets of CSS code, and watch the result appear live. I had very high ambitions for the project. There are line numbers and syntax highlighting appears live in the text box as you type. One of the greatest things is that it allows users to share their code with others as well.
3. Google’s Code Playground
Google’s Code Playground is a web-based tool that lets web developers try out all of the APIs that Google provides, tweak the code, and see the results. Google’s Code Playground lets you play around without opening an external editor, and all of the APIs are loaded for you in the Pick an API box
4. JS Bin
Dabblet is an interactive playground for quickly testing snippets of CSS and HTML code. It uses -prefix-free, so that you won’t have to add any prefixes in your CSS code. You can save your work in Github gists, embed it in other websites and share it with others. It currently only supports modern versions of Chrome, Safari and Firefox. All posted code belongs to the poster and no license is enforced. Dabblet itself is open source software and is distributed under a NPOSL-3.0 license.
9. D3 Playground
The D3.js Playground is designed to allow you to play with the D3.js library in an interactive manner. Every edit made (that results in valid code) affects the playground in realtime. Because CSS is such an important part of visualizations, you can edit CSS live, too.
10. HTML5 Playground
The HTML5 Playground includes a library of code snippets you can explore to see HTML5 in action. They include some basic getting-started examples, such as the use of the HTML5 Doctype and the audio tag (which nevertheless is a good demo of the playback features in a compatible browser). There’s an interactive form, including HTML5 elements such as range and date inputs and automated validation for email addresses and websites.
