Highlights of Using CodePen in the Frontend Community

Coding is very comfortable, given the editor’s syntax highlighting and Emmet integration. We also seriously appreciate the Tidy button — a one-click way to clean up your indentations and formatting.

CodePen for Web Design

We very much admire the service CodePen for not only the product they provide but the way they run their business.

Online Collaborative Code Editors

Overall CodePen seems like the editor of choice if you collaborate for a living.

CodePen – Perfect for Code Snippets and Examples

CodePen is a brilliant service, one which allows you to quickly embed and share examples of your work, perfect for portfolios, documentation as well as personal blogs. It enables you to get your work seen by other developers on the site where it can be hearted and commented on.

Review: How CodePen Team PRO Features Stack Up

Teaching Kids With CodePen

The main resource I used for teaching front-end programming is CodePen. I’ve been implementing the tool for some of my higher level workshops with my own colleagues so it was a no brainer to use. I tweaked the lesson plan of course so that I would present something more understandable for the younger students.

Web Designer Depot

In my opinion, you can have all the degrees or certificates or badges that you want, but in the end it comes down being able to produce something. And that’s exactly why I love codepen.io. CodePen is a front-end sandbox whose motto is “Demo or it didn’t happen” where people can view and rate your demos or even provide feedback.

I use CodePen on multiple fronts. First, it’s a terrific source of HTML/CSS/JS inspiration. There’s a ton of awesome demos that leave you thinking: I never knew that was even possible with CSS or HTML. How did they do that??

Second of all, it’s a great way to reverse engineer something you like. Granted, it’s not a tutorial site, but all of the code used for each demo is interactive where you can literally play with it and test out other people’s work to learn what does what. Or if you prefer, like GitHub, you can fork it and extend someone else’s demo in a new direction.

And last but certainly not least, it’s just a great way to practice. It offers tons of resources you can tap into, such as CSS preprocessors like Sass, LESS, and Stylus. With the click of a checkbox you can also choose to write prefix-free code or normalize your CSS. Have an external stylesheet, script or even just something from another “pen” you’d like to link to? Not a problem. If you prefer, write your code using CoffeeScript or LiveScript. You can even link to an external library such as jQuery, Zepto, MooTools, YUI and others with the click on a button. Still not finding the one you want? No fear, you’ll probably find it in the CDNJS library to which CodePen allows you to externally link. For what it’s worth, I look at CodePen as the holy grail of front-end experimentation.

Skilled Up

CodePen is a reference website aimed at advanced web developers, listing solutions for development problems created by the community and other users. It works like a showcase, where developers can show off cool, useful, or interesting web development code snippets, as well as present what they do, similar to a marketplace. There is a PRO option that allows for private "Pens" and Asset Hosting.

WP Tavern

CodePen and WordPress working together can be a beautiful thing, especially if you often publish frontend development tutorials with HTML, CSS and/or Javascript.

Design Shack

I had high hopes for CodePen, expectations that would be difficult for any free product to live up to. Fortunately, it’s everything I wanted and more.

Web Monkey

While you’re there have a look around Codepen.io; it just launched as a public beta and looks like a really nice way to share code — something of a cross between JSFiddle and Dribbble.

The Guardian

... is aimed equally at teaching others – its Pro mode offers a "live view" which updates as you code, and "Collab Mode" where multiple people can edit at the same time. It also features a paid-for "Professor Mode" which allows multiple people to watch one person teach a code example on a single page.


... CodePen is such a great tool, especially for designers who want to demonstrate their interfaces. It’s like a sandbox where other designers can tweak your codes and see the effect of their changes instantly. Putting up demos rather than just sharing the codes will help others experience immediately the power of your codes (—or not, so be careful of what you put there)! As CodePen puts it, “Demo or it didn’t happen.” But the greater benefit is that you can slowly build a library of demos that can be used as a reference by your team or others in the industry. You can leave your mark and a spankin’ portfolio, free!

The Amazing Web

I just subscribed for one year. I think you should do, too. They have some great features and I also want to support these guys. It’s a great service they are building.

Veerle Pieters design blog

CodePen is a bit like Dribbble but for coders instead of designers. Each 'Pen' can be downloaded with all the necessary files. The CSS can be SCSS, LESS or SASS. This is not to say that this isn't something for designers. I think it is, you can go there to get inspired by the innovative creations that you can see with live previews. To me CodePen looks a bit more friendly than JSFiddle, plus it has sharing features.


Big news this week: We've launched CodePen!

Net Magazine

Chris Coyier unveils CodePen, an educational and inspirational app for web designers.

Andy Clarke

Like Dribbble for code? I like it. A lot.

H/G Code

CodePen Pro is out and it looks pretty great with pair programming.

UX Rave

Use it to experiment and publish front-end code + find inspiration from others in the community.

Web Design Weekly (newsletter)

This is extremely useful for showing off demos, troubleshooting, demonstrating bugs, or anything else you can think of.

CSS Weekly (newsletter)

At first look it seems like Dabblet, JS Fiddle and JS Bin got a worthy opponent.


CodePen is a fantastic concept and implementation. I can easily see it becoming a part of a designer/developer’s process. Sketch out a few ideas in CodePen, send it around to your team, and then implement.

Ning Creators

I just thought it would be nice and useful to share this new tool I've been using with my fellow Ning Creators. Its called Codepen and it allows you to visually see the result of your markup in HTML, CSS and JS while you work.

Adrian Roselli

Codepen's recent entrance has a a couple additional features that I have found handy.

Insite Design Lab

Have you checked out this sweet new web app? You should!

The Godfounder

Emotional design: Codepen’s 404 page. I’m a bit of a fanatic for “emotional design” details since I feel that people a) enjoy a service more with some humor and might as b) share design details with others.

The Godfounder

Codepen’s mantra makes it clear what it’s all about.


The functionality and UX of Codepen makes things like jsfiddle or JSBin look like the minor leagues. Codepen really nails this, and features all things that I told myself I’d need from an online editor/snippet-share site. Not only can I favorite/follow/comment every post, I can browse the stuff other people love.

The Industry (podcast)

We share our thoughts on [...] CodePen launching it’s beta

Chris Bowler

It’s been implemented very nicely.


This website is full of those 'how did they do that?' pieces, and fortunately the code is right there to see without having to open the source/inspect element/firebug, whatever.

Creative Bloq

The model is one of a number of HTML, CSS and JavaScript projects to have been uploaded to CodePen, a new app created by CSS-Tricks creator Chris Coyier, Alex Vazquez and Tim Sabat to help designers and developers share and fork their work.

Kristian David

Codepen is one of my favorite things on the internet right now.

David Walsh

One of my favorite sites has recently become CodePen. CodePen is an incredible showcase of what developers can do with CSS, JavaScript, and HTML; thousands of developers have shown pride in their work with each pen.


I kinda think of it as a quick sketch pad for front-end web development ideas. Its also really cool to see what others are doing and being able to fork there ideas into something unique.


We have seen some of the greatest CSS3 examples in that website by the web developers around the world, pushing the limits of CSS3. I think this is just the beginning of something extraordinary happening in Web Development field.

One of the things I love about sites like CodePen is that they’re great sites to learn and get inspired at the same time.
