With the recent changes around Localstack pricing/licensing I've been hunting for alternatives. I decided that it might be a fun experiment to try rolling my own. SQS is a service I use heavily so I chose that as the first service to implement. I have more services planned and in development. A few things I think are cool: 4MB Docker Image Size Instant Startup AWS Sigv4 Authentication A little admin UI that can be helpful for development/troubleshooting Most of the SQS API implemented, the rest will soon follow :)

Looks cool! Now add (simulated) billing. ;)

What kind of things would you use this to simulate ? Is this to make sure services are wired up with permission and communicate properly before you deploy or what is the use case ? Also, why not have a dev environment where you can test things on the real thing (ideally with smaller size instances to save $)

Another SQS stand-in is smoothmq https://github.com/poundifdef/smoothmq
