// septim labs · free dev tool · .env template generator

Turn any .env into a shareable template, values never leave the browser.

Paste your .env or start from a preset. Get a sanitized .env.template with redacted values, type-inferred comments, naming convention warnings, a matching docker-compose block, and a GitHub Actions secret list.

// input

Paste your .env or pick a preset.

Variable values are redacted the moment you click Generate — they are never stored, logged, or transmitted. The output is a safe-to-commit template.

    // .env.template (safe to commit) 
    
      
    

      
    
        
    
          // docker-compose.yml env_file block
          
        
    
        
    
      
    

      
    
        
    
          // GitHub Actions — repository secrets
          
        
    
        
    
      
    
    
    
  
    

  
    
    
    
      // verify zero network calls
      
    Open DevTools (F12 or Cmd+Option+I), click the Network tab, paste your .env and click Generate. No requests fire. Every line is parsed and redacted in-browser JavaScript — no value is ever sent to a server. This tool is safe to use with real production .env files.
    
    
    
  
    

  
    
    // why .env.example files drift
    
    The stale template problem happens every sprint.
    
    
    A developer adds STRIPE_CONNECT_ACCOUNT_ID to production, forgets to update .env.example, ships it. New team member clones the repo, gets a cryptic runtime error. This tool generates the template from the actual file — it can't drift if you regenerate from source. The naming convention check catches dbUrl and apikey before code review.
    
  
    

  
    
    
    
      // the next step after the template
