LocalStack is an excellent product, and honestly one that initially I felt “no way they can do this” ironically in the same way people looked at Terraform early on and told me the same!

“Local development for cloud services is not, it turns out, nearly as silly as I once thought. LocalStack can lower costs when it comes to safely training developers, building efficient workloads, and, sure, standing up ridiculous websites. The breadth of AWS API coverage LocalStack has managed to deliver is rather breathtaking!”

Corey Quinn

Last Week in AWS & Duckbill Group

“LocalStack can be a valuable tool. It lets you run AWS services locally, making it easier to test and develop without relying on a cloud environment. This is especially useful for working with services like SQS, Lambda, and DynamoDB, where deploying and testing in the cloud can be slow and costly. With LocalStack, you can speed up development, work offline when needed, and integrate it into your CI/CD pipelines.”

Joao Marques

Software Engineer

“Really nice experience using LocalStack with Docker Compose. The Initialization Hooks in LocalStack enable you to configure resources like Kinesis streams and DynamoDB before the app starts, all running Locally with no significant code changes.”

Matthew Barlow

Cloud Infra Lead, AWS Ambassador

“LocalStack v3 is here, and it's kinda AMAZING! If you haven't tried LocalStack in a while, it's a good time to do so. They've come a long way in the last two years and are looking amazing now!”

“I’m testing @localstack for the first time and I’m fascinated. What a great tool to reproduce AWS infrastructure locally! Great solution to reduce costs with dev & staging accounts. You can even do Chaos Engineering by simulating failure in a region! 🤯
