Detailed instructions

1. Select your app stack from the App Stack dropdown — choose Node/Express, Django, Rails, Next.js, or Docker Compose.
2. Set the Include Comments toggle to 'yes' for an annotated template or 'no' for a clean, comment-free output.
3. Click Generate to produce a realistic .env file with randomised placeholder values for your chosen stack.
4. Copy the output and save it as `.env.example` in your project root, or as `.env` if you plan to replace the placeholders immediately.
5. Replace any placeholder values you need with real credentials before running your application.

Use Cases

• •Shipping a .env.example on day one of an open-source GitHub repo
• •Pasting a realistic Django or Rails config into a dev.to or Hashnode tutorial
• •Onboarding a new teammate with a pre-filled, annotated environment template
• •Scaffolding a Docker Compose project with all service hostnames and ports pre-named
• •Writing CI/CD pipeline docs that reference correct Next.js NEXT_PUBLIC_ variable names

Tips

• →Generate with comments enabled first to understand what each variable does, then regenerate without comments for a clean production template.
• →For Docker Compose projects, cross-reference the generated variable names with your `docker-compose.yml` service names to ensure they match.
• →When writing a public tutorial, regenerate the file each time you need a fresh set of placeholder secrets to avoid any visual repetition that might look staged.
• →Add your real `.env` to `.gitignore` immediately after creating it — commit only the `.env.example` generated here.
• →If your stack uses multiple services (e.g., Redis and Postgres alongside Express), generate a Node/Express file and a Docker Compose file separately, then merge the relevant sections.
• →For onboarding docs, keep comments toggled on and annotate any company-specific variables manually after generating — the structure gives you a solid base to edit rather than write.
