LocalStack Extensions

Manage LocalStack Extensions to add custom functionality, integrate third-party tools, and extend LocalStack capabilities.

lstk does not support Extensions. There is no lstk extensions command suite. Extension workflows must use the legacy localstack CLI for both installing extensions and starting the emulator — lstk keeps its own volume directory (lstk volume path, e.g. ~/Library/Caches/lstk/volume/localstack-aws), separate from the legacy volume that extensions install into, so an emulator started by lstk will not load them.

For everything else — lifecycle, IaC, snapshots, logs — prefer lstk. See the localstack skill.
