envi

Stop editing .env files blind.

Diff, scan, edit, and validate environment variables across all your profiles — right from the terminal.

---

The Problem

Every developer knows the pain:

• You pull a repo and .env is missing 5 vars that were added to .env.example
• Comparing dev vs production means opening two files and squinting
• You have no idea which env vars your code actually uses
• Sensitive values sit in plaintext, one git add . away from disaster

envi gives you a single dashboard for all of it.

~ CHANGED	Different values between files

Press Tab to cycle through diff targets.

Code Scanner s

Scans your project for env var references across 10+ languages:

process.env.VAR        (JS/TS)          os.environ["VAR"]    (Python)
env::var("VAR")        (Rust)           os.Getenv("VAR")     (Go)
System.getenv("VAR")   (Java)           ENV["VAR"]           (Ruby)
${VAR} / $VAR          (Shell/Docker)   getenv("VAR")        (PHP/C)

Reports vars used in code but not defined, and vars defined but never used.

Search /

Live fuzzy search across variable names and values.

Validation

Automatic warnings for:

• Empty values
• Potentially sensitive unencrypted values
• Non-UPPER_SNAKE_CASE keys
• Variables missing from other profiles

Cross-File Awareness

The details panel shows which other profiles contain (or are missing) the selected variable — no more guessing.
