JeremyCMorgan recommends Floci, a lightweight, free local AWS emulator (a LocalStack alternative) with 31.6k GitHub stars and 3.5k forks under MIT license. It emulates EC2, ECS, S3, SQS and more, running via Docker/docker-compose. If your pipeline depends on AWS events or services, reproducing those interactions locally shortens feedback loops without repeatedly deploying test infrastructure.
