Show HN: Hiraeth – AWS Emulator

Posted by ozarkerD 2 days ago

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 :)

If you’re looking for requests ;-), I would love an ECS (and specifically Fargate) emulator that actually ran Docker containers locally as though they were in ECS

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 $)

Intergration testing is one. You can run this in your ci/locally to speed up tests. Or just for local dev. We do this with localstack[1]

Yep integration is my use case as well. It’s nice to not have to worry about setting up real infrastructure for testing client code, parallel execution if you’re on a team, clearing out state each run, etc…
