What is MiniStack and how does it compare to LocalStack?

MiniStack's a lightweight, open-source AWS service emulator—211 MB Docker image, 31 services, instant startup. Crushes LocalStack's bloat (1 GB, 15-30s boot) in benchmarks.

Is MiniStack free and production-ready?

Yes, MIT license, fully open. Benchmarks show it handles S3/SQS/DynamoDB/Lambda fine; great for dev/testing, not prod replacement.

Should I switch from Floci or LocalStack to MiniStack?

If you need broad service coverage (Route53, ECS, VPC) and fast starts—yes. Floci edges DynamoDB reads; stick if that's 90% of your work.
