What are the alternatives? I primarily used it for S3 and SQS emulation.

I haven't used this yet, but there's also https://github.com/robotocore/robotocore. It came up on HN a few days ago: https://news.ycombinator.com/item?id=47420619.

It's not a complete replacement, but if you're in a Python ecosystem, you might find Moto to be of interest.

at least some parts of localstack seemed to be built on moto, based on a brief look at some point

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.

I haven't evaluated it deeply yet, but I saw https://github.com/hectorvent/floci

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).

I am about to test this one http://docs.getmoto.org/en/latest/index.html

I've fiddled around with https://docs.getmoto.org/en/latest/docs/server_mode.html

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

MinIO is a drop in replacement for S3. I plan on switching to this as soon as I can. For now, I just pinned localstack to 4.14.0

I have some bad news for you: https://news.ycombinator.com/item?id=47000041

It's comedic that they said that right after Minio pulled the same thing as localstack.

RustFS is a good and simple-to-usr alternative for MinIO.

Too late.
