First minio and then localstack, as an open source maintainer I find that abandoning their community is bad faith. I totally get wanting to monetize but removing the free product entirely feels like such a betrayel.

Luckily, I've been vibing with Devin since this started having it build a cleanbox emulator on top of real s3 tuned for my specific use case. It's a lot less general but it's much faster and easy to add the sort of assertions I need in it. It's no localstack but for my limited use case it works.
