Accelerate infrastructure development with AWS CloudFormation intelligent authoring in IDEs
Today, AWS CloudFormation announces the launch of the AWS CloudFormation Language Server, a new capability that brings intelligent authoring, early validation, troubleshooting, and drift management directly into Integrated Development Environment (IDE) through the AWS Toolkit. This new feature empowers developers to build infrastructure faster and deploy safely.
With this launch, developers using Visual Studio, Kiro, and other compatible IDEs can now benefit from context-aware authoring powered by the Language Server. It offers built-in auto-complete, schema validation, policy checks using CloudFormation Guard, and deployment validation directly within the IDE. For example, it immediately flags invalid resource properties or missing IAM permission requirements, while the drift-aware deployment view highlights differences between your template and deployed infrastructure, helping you spot configuration changes made outside of CloudFormation. These capabilities help developers identify issues, such as syntax errors, missing permissions, or configuration mismatches before deployment. It also provides a drift view that highlights differences between the current template and the deployed stack configuration. By integrating validation and real-time feedback directly into the authoring experience, the CloudFormation Language Server keeps developers in their flow state, turning infrastructure coding into a seamless experience, and improves infrastructure safety. This unified experience enables developers to move from design to deployment faster while maintaining compliance and best practices, spending more time building and less time troubleshooting.
The AWS CloudFormation Language Server is available in all AWS Commercial Regions where AWS CloudFormation is supported. To get started, install or upgrade the AWS Toolkit. To learn more, refer to AWS CloudFormation Language Server.
