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.
gkoberger•13m ago
That's the hard part about tools like this. They're too simple to be used for anything important, and as soon as the creator follows that path you end up in a situation where it's too simple for anything complex and too complex for anything simple.

Amazing platforms like Glitch ran into this problem.

(Some did pull it off! Like how Vercel built a kingdom out of `now`.)

> every pen is deployable

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.

Any free hosting solution tends to spiral towards abuse at some point.

Does it work? I'm a paid user, but set up a new free account to see if the deployment stuff worked there too (as I was linking to it from elsewhere) and it said I had to upgrade to a plan that supported it.

Where do you think the AI is getting the code from your prompts from.

If the owner reads this, I'd consider getting codepen.app registered as a public suffix [1].

https://jsfiddle.net/ used to be also very popular, I see that it is still available, but haven't used it in a while.

Which other alternatives do people use now days?

https://jsbin.com is what I've used since forever, it's fast and easy, used to use JSFiddle before that. I think you used to be able to create "bins" without having to login way back though. Honestly don't find much use for them anymore nowadays, if I want to share any web/web-like I do it via my own servers + domain and send links to people.

Whoah… CodePen… didn’t remember that… since the overflow of ai tools, this feels a bit like ancient tech. Used to love CodePen.
