+## Lambda Managed Instances
+
+LocalStack provides local testing support for Lambda Managed Instances. We support all of the new APIs, as well as the CloudFormation and Terraform resource types. All the same configuration is therefore possible on your local machine, without needing to modify your infrastructure as code (IaC).

+::note
+
+This is an evolving feature and current support is scoped as follows:
+
+- We **do not spin up any additional EC2 instances**. LocalStack runs Lambda functions in containers on your local machine.
+
