Although we like the offline web development editor and IDE, we often hate the inconvenience of editing the code and then open the browser to test the changes. Even if you open a browser tab with a test file, you must constantly jump from one editor to another and refresh the tab before any changes are displayed in the output. Hence we tend to work on sites that display output in real time.
Conveniently, the editable code and the testable output are displayed sides by the side. Another fun of these online playgrounds is the vast network of web designers and developers who publish code snippets for worldwide reference.
CodePen is one of my favorite code editors. CodePen has some cool and unique features that make it one of the most popular online code editors in web development.
The features of CodePen are:
- You can use the syntax of the preprocessor like Sass, LESS, Stylus. Markdown, Haml, Slim, Jade
- Use the CodePen portfolio to showcase your talents and design your own portfolio home page.
- You can find part-time jobs using the Hire Me to feature service.
- Any resource can be embedded on any other website.
Dabblet supports logging in with a Github account. The code snippet can be saved either anonymously or in the user’s Github: gist so that users can embed the code snippet into their site or share it with others.
Mozilla’s HTML/CSS online interactive learning site, Thimble: Edit on the left, live preview on the right, with lots of real-world examples. The site is part of Mozilla’s recently launched Webmaker program, designed to help regular users learn HTML and CSS online.
Thimble provides a two-panel design with code editing with syntax highlighting on the left and a web page preview in real time on the right. If the user is satisfied with the results, it can be published by the blue “Publish” button at the top right. Share your design with your friends via the Twitter Post button provided.
In addition to debugging code, you can easily post to the community, forum or social media to share or ask questions with friends. A lot of different class libraries are integrated for everyone to choose.
CSSDesk tool is a standard CSS sandbox, which can give CSS beginners the greatest help. The website is divided into three columns. We can easily modify the code on the left side to see the changes of a CSS attribute to the HTML element. Impact, even we can put the entire site into it for debugging, and save the debugged file as HTML. The only regret is the lack of code hints, which require manual input of CSS properties.
It can be seen that the author of CodeMirror is a person who is very yearning for freedom. But his CodeMirror is definitely not simple, take a look at the following list:
- Google Earth KML sampler
- The qooxdoo playground
- A cool tutorial about the element
- An online IDE for the Orc programming language
- Google’s API playground
- Raphaël Live
- JS Bin
- The RokPad plugin for Joomla
- The scraperwiki editor
- jsLinb UI Builder
These online code editors are based on CodeMirror, and I am not surprised. There is a JS Library that you are familiar with.
The positioning of CodeMirror itself is also very clear, short and fine, but the code quality is very high. In the group of Google Group, people are enthusiastically carrying out the discussion of various transformations with CodeMirror, which is welcome to him.
If you have a project that requires online code editing, what are you waiting for? CodeMirror is definitely your best choice.
7. JS Bin
The feature of Codeanywhere is that you can write code anytime, anywhere (although I think the code on the phone is a bit funny).
Codeanywhere supports connecting to FTP Server, Dropbox, Github, such as Dropbox. You only need to have an account. After connecting to Dropbox, Codeanywhere can create files such as HTML on Dropbox. The code you write is stored on Dropbox.

In addition, Cloud9 space does not support binding its own domain name, and can not permanently keep the application online. In addition, Cloud9 space is good for testing programs and code.
