CodePen 2.0 Launch: Real-Time Collaboration and New Features

I recently launched CodePen 2.0, a project requiring more effort than the original creation. This update introduces powerful real-time collaboration, allowing users to invite co-editors and work together seamlessly. We also added support for npm packages, new Blocks like MJML, and direct deployment capabilities. Early tests with live streams and email building proved the platform is robust and ready for complex workflows.

I friggin love how I can make little websites and deploy them right through the Pen Editor.

    I've been a CodePen user since the very early days. Have always loved the platform. I hate to be negative, but I'm honestly not a fan of the 2.0 release. What I loved about CodePen was just being able to try out something really quick and simple. But the new interface makes me feel more like I'm building a website inside of a website.

    It will be interesting seeing how this evolves. Any free hosting solution tends to spiral towards abuse at some point. Still trying to solve it for my own stuff.

    That said, I do wonder how valuable something like codepen is in the current meta. I really no longer look at code. I'm not referencing examples, I'm just prompting for what I want / inputting images as context.

    This is awesome. Been a CodePen user/fan since it launched (and a fan of Chris/CSS-Tricks for even longer). Really nice to see CodePen evolving.

    I don't use it as much as I used to but every so often I hack something up in it for a quick PoC. I'll say the new ability to deploy got my attention. Really handy to be able to deploy a prototype or demo of something and toss it over the fence.

    Used to love this site back when you could see what other craftsmen were actually creating by hand.

    I've been wondering how CodePen is surviving the AI onslaught - the core thing CodePen has always represented to me is to showcase the amazing hand craftsmanship of CSS HTML JS developers. Obviously that has changed, so I wonder what it means for CodePen - presumably they need to change their business model in some way.

More from this day
