Ugh, I hadn't heard the news about the LocalStack licensing changes. I had some great results building AWS services for local dev as well as CI/CD and testing in GH actions with LocalStack in previous jobs.
I secretly always hoped Amazon would buy out LocalStack and make it the official free local development environment for AWS work, but I guess it probably would reduce revenues spent on AWS based dev and test environments. The compatibility with the AWS CLI was mostly excellent in my experiences.
for most teams the pain was not missing features -- it was drift. you build against the emulator for months, then hit some edge case in prod where the S3 response format differed slightly or DynamoDB error codes were not qui
I really don't see how any clone is going to manage to do what localstack couldn't - maintain compatibility with tons of AWS services while not getting paid for it. If this were viable, why would it not have worked before?
The only things I can think of are that perhaps LocalStack was just a mess of a codebase that couldn't maintain velocity or attract contributors, or it just failed to steward new contributors or some such thing.
Personally, I would get value out of really solid compatibility of the base features of a few core services (sqs, s3, kms, and maybe dynamo are the main ones that come to mind) with a light weight gui interface and persistence.
If I’m getting into esoteric features or some “big” features that don’t make sense locally, then I just spin up a real dev account of aws, so I know I’m getting the real experience.
Hello! We won't have the broad coverage that Localstack has... we're not aiming to be the "next Localstack"... just want to keep the core services that were available for free in the LS community up to date. If you’re looking for larger services like MWAA, sorry, but we won't be supporting them.... Most core AWS services don't receive many updates anyway (their APIs don’t change drastically or frequently)
"LocalStack was just a mess of a codebase" - very true.
I do think there's potential to semi-automatically create a compatible suite of services, but it'll require some very talented use of LLMs and some novel testing approaches. Not something I want to sign up for.
I evaluated Floci, but that has the typical issues you'd expected with freshly minted vibe code.
I suppose (among many other things) LLMs are changing this. We no longer need that many contributors when we can use AWS docs, intercept AWS API calls and give it to AI agent to mimic. Of course, contributors are still needed for maintaining tests and validations.
Thus far I've tried that (rejected), Floci (not great), and now looking at this.
This one is 7 days old.
I'm eager to have a localstack replacement, but these are a long way off from being mature enough. I suppose this is just the new state of software? Shiny website, big claims, AI coded, insufficiently tested.
Out of curiosity, why did you reject Floci? It lacked some feature I needed, so I just went ahead and added them. My needs were not that complex and it has patterns to test that implementations match AWS. I agree it’s lacking things, but the bones aren’t that bad.

The problem is that everybody needs different "core" features

For instance, I don't care about any of those features at all. But I would care a lot about EC2, RDS, and ElastiCache Redis

Already lying or totally unreviewed AI slop ?
