Thus far I've tried that (rejected), Floci (not great), and now looking at this.

This one is 7 days old.

I'm eager to have a localstack replacement, but these are a long way off from being mature enough. I suppose this is just the new state of software? Shiny website, big claims, AI coded, insufficiently tested.

Out of curiosity, why did you reject Floci? It lacked some feature I needed, so I just went ahead and added them. My needs were not that complex and it has patterns to test that implementations match AWS. I agree it’s lacking things, but the bones aren’t that bad.
