Use `astro env variable` commands to list, create, update, delete, and export environment variables managed through the Astro Environment Manager. You can scope a variable to a Workspace or a Deployment, and you can link a Workspace-scoped variable to specific Deployments. To manage these variables in the Astro UI instead, see [Create environment variables in the Astro UI](/docs/astro/create-and-link-environment-variables).
