No, unless you are maintaining an existing AWS CDK v1 codebase. The package reached end-of-support on 2023-06-01 and receives no updates. New projects should use AWS CDK v2. Existing v1 users should plan migration; while the package is stable and has no known vulnerabilities, staying on an unsupported version introduces long-term maintenance risk.AI-flagged interpretation of the facts on this page — verify before relying
Before you install

What it is and what it does
AWS CDK Core is the foundational library for AWS Cloud Development Kit v1, providing the base classes (Stack, Stage, Construct) and synthesis infrastructure needed to define AWS infrastructure in Python code. It translates your Python constructs into CloudFormation templates for deployment. The library handles stack organization, nested stacks, cross-stack resource references, and asset management through configurable synthesizers.
This package is the entry point for building CDK applications in v1, but it is no longer maintained. AWS announced end-of-support on 2023-06-01, and the project recommends migration to AWS CDK v2. While the package remains functional and has no known security vulnerabilities, new projects should use v2 instead, and existing v1 users should plan upgrades.
Use it for
- Maintaining or extending existing AWS CDK v1 applications that have not yet migrated to v2.
- Defining multi-stack AWS infrastructure with shared resources and cross-stack references.
- Creating nested CloudFormation stacks programmatically without writing raw YAML or JSON templates.
- Organizing large infrastructure deployments across multiple logical stages (dev, staging, prod).
