This was a goal for me too. Although I mostly work with dynamodb via localstack so I focused on getting that to work.

So yes, it does work with localstack, provided the endpoint_url is set for that profile in the aws config file like so:

[profile local-v2]

region = us-east-1

aws_access_key_id = fake

aws_secret_access_key = fake

endpoint_url = http://localhost:8005

Dynamodb-local isn't currently supported, but it will be.
