Key Features

  • Intelligent Authoring: Context-aware auto-complete, schema validation, and policy checks.
  • Early Validation: Flags invalid properties and missing permissions.
  • Drift Management: Highlights differences between templates and deployed infrastructure.
  • Deployment Validation: Validates deployments directly within the IDE.
