Does a similar such thing exist for GCP?

There is some coverage within the gcloud sdk:

The firebase stack can run 100% local as well.

i wish aws...and to be honest, most cloud providers put more effort into the development experience.

they have local dynamo, but i believe that's the only official appliance they provide.

I think it's especially necessary for the proprietary products -- dynamo being a great example.

I'll take a moment to call out snowflake for this as well -- it's really frustrating to not be able to quickly (within milliseconds) and easily (i shouldn't need to get credentials from elsewhere in my org) setup & teardown databases while under test.

This tool is very useful for integration testing, but unfortunately it can be rather slow.

I’ve been saying for a couple of years whoever builds a tool to one click deploy an AWS alike to run on local bare metal has built the next billion dollar a year company.

I know of a lot of big shops that are desperate to get out of the cloud due to 7-8 figure AWS bills but their software and engineering is too tightly wound into AWS tooling.

Yes I use localstack a lot and it's very nice but VERY slow and I can't really understand why.

Is it the startup time or the overall performance during runtime?

Hey - LocalStack founder here. Thanks for the feedback.

We're currently investing some time and resources on refactoring the code base to improve the performance. We have some improvements in the pipeline which we should be able to roll out within the next 1-2 weeks.

Performance (as well as general UX) is definitely high up on our priority list, and we'll continue to invest heavily in this area. Stay tuned!

Happy for any additional suggestions and questions you may have.
