# Envarly

Edit, audit, and protect your Windows environment variables. Preview every change before applying, clean up PATH entries with folder pickers, and keep registry writes intentional.

`winget install Envarly.Envarly`

## Features

Everything you need to manage environment variables safely.

### Practical PATH editor

Reorder entries, validate each one with a live ✓ / ✗ existence check, switch between list and plain text, move through rows with the keyboard, and choose folders — all without leaving the editor.

### Secret detection

Name-based heuristics and value-pattern matching across 35+ token formats — GitHub, AWS, Anthropic, Stripe, npm, and more.

### Diff detection

Detects registry changes made by other processes while Envarly is open. Shows a diff with selective apply per entry.

### Snapshots & demo mode

Save named snapshots of your full environment, encrypted with DPAPI. Demo mode opens realistic sample data for screenshots and walkthroughs without touching your registry.

Also included

### Environment guidance

Shows short descriptions for well-known variables and warns on unresolvable %VAR% references in path entries.

### Local undo before staging

Multi-step Ctrl+Z in the detail panel before staging. Drag reorders and text edits are independent undo steps.

### Apply progress & log

A progress bar and per-variable log show exactly what happened while staged changes are written to the registry.

### Import / Export

Read and write .json and .reg formats, plus export to PowerShell, DSC, and Ansible-friendly files. Preview before any write.

### Resizable panels

Drag the sidebar and snapshots panel to the width you want. Sizes are remembered across restarts.

### Check command

Find out why a command isn't found — searches the effective PATH for a name or exe path and flags shadowed duplicates.

## Who is it for?

Envarly is built for developers and power users on Windows 10 and 11 who frequently edit User and System environment variables — and want a safer, more visual alternative to the built-in Windows Settings panel.

Whether you are managing a cluttered PATH variable, rotating API keys stored as environment variables, importing a team's .env baseline, or restoring a snapshot after a bad install — Envarly gives you full visibility before any registry write happens.
