Features

This chapter covers the core features and capabilities of Environment Manager.

Features

• Diff environments: Compare .env files across dev/staging/prod and spot missing or changed variables
• Sync variables: Copy missing variables from one environment to another
• Validate configs: Check for required variables, empty values, and format issues
• Audit report: Generate a full audit of all environments as JSON or text
• Template generation: Create .env.example from your actual .env (strips values)
• Support for comments and sections in .env files
• Detects common mistakes: trailing spaces, duplicate keys, unquoted special characters
• Python stdlib only — zero dependencies
