envui

A visual .env file editor built with Go and Fyne.

Why?

Managing .env files sucks:

• Which vars are missing vs .env.example?
• What's inherited from shell vs explicit?
• Did I accidentally commit a secret?
• What's different between local and staging?

envui gives you a visual editor to manage environment variables across multiple .env files.

Features

• Visual Editor - Table view of all variables, click to edit inline
• Secret Masking - Auto-detect and mask sensitive values (API_KEY, PASSWORD, TOKEN, etc.)
• Multi-file Support - Switch between .env, .env.local, .env.staging, etc.
• Source Tracking - See which variables come from file vs shell environment
• Comment Preservation - Your comments stay intact when saving
