Cloud providers like AWS, GCP, and Azure should offer local emulators for development. This would encourage developers to utilize their services more.
I currently work with several AWS serverless stacks that are challenging or even impossible to integration test locally. While Localstack provide a decent solution, it seems like a service that AWS should offer to enhance the developer experience. They’d also be in the best position to keep it current.

Microsoft used to with their Azure Service Dev Kit. the ASDK was a single-node "sandbox" meant to emulate the entire Azure cloud locally. They may have something similar now but paired back

CloudFlare for their serverless offering did it, and it works decent.

They should... put work into sacrificing revenue?
boomlinde 13 minutes ago [-]
Without the infrastructure behind it to make it make sense, cloud platforms just seem like convoluted ways of storing data and launching applications/VMs to me.
The only functional use of a tool like this to me would be to learn how to use AWS so that I can work for people who want me to use AWS. Would that not be to Amazon's benefit?

If you have a local “digital twin” of the service, it makes it much easier to develop against using AI. This would likely drive adoption.

It's even easier for their revenue if you have to provision dev AWS environments for everyone.

It's not clear that it would be a net-negative on the revenue.
It could encourage more development and adoption and lead to being a net-positive for the revenue.
hmartin 3 hours ago [-]
It's a fair point but iff you neglect that the overwhelming revenue drivers for these services are large corps who are already locked-in.
Devx doesn't matter at all once you're there.
The myopathy among us "online people" is assuming number of voices here and elsewhere correlate to revenue.
It does not.

If it's irrelevant whether or not individual developers are on board, why are Amazon offering a free plan?

This project would be comical if it takes off. In Romanian this name means "a small pile of hair", but informally it's only used as a synonym for pubic hair.

In Latin it's a tuft of wool, best known for expressions of valuelessness like "flocci non facio," meaning 'I don't consider it worth a tuft of wool.'

> LocalStack's community edition sunset in March 2026 — requiring auth tokens, dropping CI support, and freezing security updates. Floci is the no-strings-attached alternative.

I run several Docker services on EC2 and testing locally before deploying has always been painful. This looks promising for catching config issues before they hit production. Does it support EC2 + RDS together in local mode?

This is exactly what I was waiting for.
Although I love localstack and am grateful for what they have done, I always thought that an open community-driven solution would be much more suitable and opens a lot of doors for AWS engineers to contribute back. I’m certain that it’s on their best interest to do so (specially as many of their popular products have local versions)
It’s a no-brainer to me as AI adoption continues to increase: local-first integration testing is a must and teams that are equipped to do so will be ahead of everyone else

100% this. especially with agentic workflows actually mutating state now. local testing is the only safe way to see what happens when a model hallucinates a table drop without burning an actual staging database.

Cool, I've tried localstack before and cant wait to give it a try
Anyway, do anyone know if there're similar stuff but for gcp? So far https://github.com/goccy/bigquery-emulator helped me a lot in emulating bigquery behaviour, but I cant find emulator for the whole gcp environment.

is all of this is vibe coded?
seer 14 minutes ago [-]
Isn’t a “local emulator of cloud services” kind of the perfect project to be vibe coded? Extremely well documented surface to implement, very easy to test automatically and prove it matches the spec, and if you make some things sub optimal performance wise, that is totally fine because by project will not be used in a tight loop anyway - e.g. it will just need to be faster than over the network hop plus the time it takes for the cloud to actually persist things. This can just need to do this in ram and doesn’t need to scale.
So I’m shocked cloud providers haven’t just done this themselves, given how feasible it is with the right harness

It does to the person who asked the question.
Whether their concerns are driven by curiosity, ethics, philosophy, or something else entirely is really immaterial to the question itself.
asteroidburger 12 minutes ago [-]
Not necessarily. Would you respond the same if the previous person said, "Was this built using an IDE" or "What qualifications do you have to write this software"?
Shit code can be written with AI. Good code can also be written with AI. The question was only really asked to confirm biases.

I dont automatically dismiss ai slop but when its obvious this was barely reviewed and sloppily committed with broken links 404ing or files missing from git, then it is slop.
Using llm as a tool is different from guiding it with care vs tossing a one sentence prompt to copy localstack and expecting the bot to rewrite it for you, then pushing a thousand file in one go with typos in half the commit message.
Longevity of products comes from the effort and care put into them if you barely invest any of it to even look at the output, look at the graveyard of "show hn" slop. Just a temporary project that fades away quickly
There are no code commits. The commits are all trying to fix ci.
The release page (changelog) is all invalid/wrong/useless or otherwise unrelated code changes linked.
Not clearly stating that it was AI written, and trying to hide the claude.md file.
The feature table is clearly not reviewed, like "Native binary" = "Yes" while Localstack is no. There is no "native" binary, it is a packed JVM app. Localstack is just as "native" then. "Security updates Yes" .. entirely unproven.

Its pretty easy to step over those limits.
Also localhost and presumably this are good for validating your logic before you throw in roles, network and everything else that can be an issue on AWS.
Confirm it runs in this, and 99% of the time the issue when you deploy is something in the AWS config, not your logic.

Exactly, especially when people are starting out, don't have a clear understanding of the inner workings of the system for whatever reason. Jobs are getting harder to find nowadays and if during learning, you make one mistake, you either pay or the learning stops.
