Ministack (Replacement for LocalStack)

5 hours ago

MiniStack is a free alternative to LocalStack, offering 30 AWS services on a single port with real Postgres, Redis, and Docker containers.
It provides core AWS services with real infrastructure, such as RDS for actual databases, ElastiCache for real Redis, ECS for Docker containers, and Athena with real SQL via DuckDB.
MiniStack features faster startup time (~2 seconds), lower memory usage (~30MB idle), a smaller Docker image (150 MB), and is free under an MIT license, unlike LocalStack which is now paid.
The comparison table highlights that MiniStack includes many services for free, like Lambda, EC2, and Cognito, which are paid in LocalStack versions, and uses real containers instead of stubbed responses.
