CloudHealth. 1500 AWS accounts, it does the job well enough

"1500 AWS accounts"

You just blew my mind. We have two accounts and it gets messy sometimes.

Messy? Isn't one of the points of having multiple accounts to reduce mess?

Yeah except having to navigate between the two can be tricky. Also that means we have multiple dynamos and multiple cognitos (in our case, test and prod), which is a pain.

I use Firefox for the prod console and Chrome for the test console. Obviously that system doesn't scale past 3-4 accounts. ;)

Firefox Container Tabs work well here for quite a while. But after 20 or so the list of containers will get very long.

I would say that once you get beyond those additional two-three accounts, you have tackled the mess and scaling to 1500 gets easier. And yes it's mind blowing.

I wouldn't roll it yourself without a serious security audit. A tool like that is just bad opsec, would help an adversary immensely.

Python, multiprocessing and boto3 with assume role.

1000+ accounts takes a few minutes.

That would be a handy tool.
