MiniStack

MiniStack is a free, MIT-licensed, drop-in local AWS emulator (a LocalStack alternative). It emulates 60+ AWS services (S3, SQS, DynamoDB, Lambda, IAM, STS, RDS, etc.) behind a single local endpoint, so you can develop and test AWS-based applications entirely offline, with no AWS account, API key, or telemetry.
