Codepen alternatives?

Hello campers!

Are there any alternatives to codepen?

I have been building building apps for front-end library using react and noticed it’s kind of hard to deploy on codepen trying to un-refactor all mycode to one bundle and etc…

I have been using Heroku but found out that hosted apps aren’t really free because of given amount of “dynos”.

I also heard that page can just host one repository in my github.

If I have to deploy multiple apps on cloud to show my apps, what’s the best option out there to do it for free?
If I have to pay, what service do you recommend? I heard AWS is pretty good.

Heroku does have free offerings.
You can have multiple GitHub repositories.

Thanks! I will check them out.
