The .env Template Library gives every stack a fair starting line. Pick Node.js, Next.js, Django, Laravel, Rails, Flask, or Vite and get a commented .env skeleton with the variables those frameworks most commonly need.
Each template fills safe sample values (like PORT=8080) and leaves secrets blank, ready for you to paste into a secret manager or a real file. Extra variables prompt it to append your own KEY=value lines untouched.
The whole library ships in the page, so generating a template is instant and private.
