Why devcontainer-cli?

• Zero dependencies at runtime — just commander and chalk
• Template-based — start with minimal, standard, or advanced presets
• Validation built-in — catch config errors before deployment
• Environment-aware — manage dev/staging/production configs in one file
• Diff support — compare configs across environments
