Env File Generator — Create .env Files and Templates Fast
List your variables and get a clean .env file plus a safe .env.example template to share with your team.
What is Env File Generator?
Cobain AI's Env File Generator helps you create clean .env files and shareable .env.example templates without fuss. List the configuration your app needs — database URLs, API keys, ports, feature flags — and the tool formats them into a well-organized environment file with comments and grouping. It also produces a safe example template with placeholder values, so you can commit configuration structure to your repo without leaking secrets.
