Any dev real world scenarios training platform?

After seeing a post the other day about a project called Sad Servers, I was wondering if there was an equivalent for dev. Basically, the project I'm talking about is a training platform for sysadmin, you arrive on a Linux VM, there is a little scenario that says the machine has a problem, you have to solve it. It's similar to what exists in the hacking field with sites like Hack The Box or TryHackMe. I'm only a dev, not a hacker or sysadmin and yet I love this kind of platform, it's entertaining and a great way to learn.

Do you know of anything that could be similar for devs? Whether it's in the cloud or containers to run locally.

I can for example imagine an environment with a few services running, a customer ticket type scenario with a bug to solve. Or maybe a feature to add, to modify. In short, a way to learn, to train closer to reality than Leetcode, and more fun and immersive than an exercise in a tutorial.
