Manage .env files across environments with syntax highlighting, secret masking, missing key detection, and Pro team features.

Features

Free

Syntax highlighting — color-coded keys, values, and comments in all .env files
Secret masking — hides sensitive values behind *** so they don't leak in screen shares
Environment switcher — quickly open any .env.* file from a command
Missing key detection — compares all .env files and lists keys that are missing from any one of them
Status bar indicator — shows the active .env file name at a glance

Pro — marketplace.dashovia.com

Environment diff — side-by-side visual diff between any two .env files (dev vs staging, staging vs prod)
Generate .env.example — auto-strips secret values, keeps key names, ready to commit
Team sync (roadmap) — share encrypted env variables with your team
