Service Reference
Overcast implements the most common local-development workflows across AWS service APIs. Each service page lists supported, partial, work-in-progress, and unsupported operations with notes about emulator-specific limitations.
Start Here
- S3, SQS, DynamoDB, Lambda, API Gateway, and EC2 / VPC have the broadest workflow coverage.
- CloudFormation is the main entry point for CDK and IaC-driven deployments.
- IAM stores roles, policies, users, groups, and instance profiles, but is intentionally not a security boundary.
- Unsupported operations return AWS-shaped
501 Not Implementedresponses withx-emulator-unsupported: true.
