Envfy 🚀

Envfy is a simple and developer-friendly CLI tool to manage multiple .env environments for your projects. It helps developers quickly create, switch, and manage environment files (.env.local, .env.dev, .env.stage, .env.prod) and also generates a .env.example file for sharing with your team.

Built with developer experience (DX) in mind. Keep your workflow simple, consistent, and hassle-free.

Features ✨

• Interactive creation of .env.* files
• Optional environment variable creation
• .env.example automatically generated
• Switch between environments easily
• Set or update variables in specific environment files
• Check which environment is currently active
• Custom help command for quick reference
