They were, but they moved off them - probably with a move away from OSS as a long term plan.
I've used Localstack extensively for ~7 years, and I will rejoice when I can finally be free of it. I've found it to be low quality software, and full of bugs.
In my first few hours:
- it failed with Pekko due to not returning version information properly
- it doesn't support range requests in S3 (!)
This project is 8 days old. It did support most of my workflow, but ... I don't get the warmest of fuzzies relying on something so brand new. But here we are in the age of vibe coded AI replacements, what a time to be alive.
For S3 emulation, I'm using rustfs. It's very compact and fast to run, and you can just start it with `docker run` inside tests if you don't want to set up a full integration test harness.
I used an SQS-on-top-of-Redis emulation before, but I can't recommended it now (no updates for 6 years).
It didn't support the one thing I wanted but it was so easy to find the right place in the code, I was happy. Never got to continue it though or turn it into a PR
