Hey HN, I built Codeground (https://codeground.ai) because I kept needing to try a small piece of code and didn't want to set up a local environment for it.

It's an online playground with an inbuilt AI. One can talk to AI about their code or can ask AI about the code.

It has a ton of other dev tools under one umbrella so that devs don't have to switch to N different apps again and again.

And also a small gaming arcade to take a break.
