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 :)
