|---|---|---|
| Cloud Engineer at a educational organization with 501-1,000 employees | 4.0 | I use LocalStack for local AWS development and testing, saving 50-60% on infrastructure. It offers a faster feedback cycle and is stable, but I wish for full AWS compatibility and improved performance, as local success doesn't always transfer to AWS. |
| Software Engineer at a outsourcing company with 1,001-5,000 employees | 4.0 | I use LocalStack for AWS environment simulation, especially for Vault, to lower costs. Its third-party integrations and cost savings are valuable, though I'd appreciate improved CLI feedback. It's stable and very useful. |
| Senior Engineer at Integer Consulting | 4.5 | I find LocalStack excellent for stable local testing of AWS components like DynamoDB, significantly boosting productivity and saving testing time. While I'd like better performance simulation and faster AWS updates, I rate it 9/10. |
| Software Engineer at a tech services company with 501-1,000 employees | 5.0 | I primarily use LocalStack for local testing of DynamoDB, SQS, and SNS, which greatly improves my software quality and enables comprehensive container testing. It's easy to configure and perfect for my needs, so I rate it highly. |
