Hello thanks a lot for this. I was also thinking about running tests using cfnlint. I heard from someone that I could use localstack which would deploy locally, confirm if the template deployed all the resources properly and would not incur charges. True?

Localstack may help to some extent for sure, although probably not catch all issues.
I would expect service limit issues and regional differences perhaps not getting caught, and any timing related issue as well.

But I have not used localstack recently, so not sure about the current quality of the emulation.
I think more of the value may come from faster feedback loop rather than resource cost.

I.e. it may reduce the cost of your time more than the cost of AWS resources -which is valuable.
