It uses the "Awesome Lists" format many of which are more of huge lists of almost everything noteworthy on specific topic not a curated list with high standards. Often created for the purpose of farming github stars and contributions for the author of list and people contributing to it.

Even if the lists aren't of best quality, they can sometimes be useful as starting point for researching a new topic. Just need to keep in mind that some things might be missing and you need to evaluate and compare the quality of each linked project yourself.

I fail to see the point of a curated-but-unmaintained list when you can just go to the GitHub actions marketplace, where at least there are community stars that let you know how popular a given action is.

Similar to that tool but more than a simulation, you can use `act` to run GitHub Actions locally. Great for testing before deploying.

Right, I’m aware of ACT; I saw this tool whose description seemed more interesting than ACT, but as I posted, it’s been abandoned.
