lpop stores your environment variables in the system keychain (macOS Keychain, Windows Credential Manager, Linux Secret Service), making them secure and easy to manage.

Never lose your secrets - Call lpop .env.local to store all your secrets from an existing file
Delete your repos - when you clone again, just call lpop .env.local to get your secrets back
Clone multiple times or use git trees - call lpop .env.local and your secrets appear
Use with AI Coding tools - run Claude, or Cursor on 20 different copies of the repo, without ever giving it access to secrets
Skip .env files entirely - Use lpop env -- npm start to run commands with variables directly from keychain

🚀 Installation

# Install globally with npm
npm install -g @loggipop/lpop

📖 How It Works

lpop automatically detects your git repository and organizes variables by project and environment:

🔐 System Keychain
├── 📁 lpop://user/project
│   ├── 🔑 API_KEY - repo level api key
│   └── 🔑 SECRET_TOKEN - repo level token
├── 📁 lpop://user/project?env=development
│   └── 🔑 DATABASE_URL - development database
└── 📁 lpop://user/project?env=production
    └── 🔑 DATABASE_URL - production database

🎯 Quick Start

1️⃣ Store your environment variables

# From a .env file
lpop .env.local

# Or add a single variable
lpop API_KEY=secret123

2️⃣ Retrieve your variables

# Get all variables and write to .env.local file
# Uses .env.example as template if available
lpop

# Or specify a different output file
lpop .env.dev

3️⃣ Use different environments

# Store production variables
lpop .env.production --env production

# Retrieve staging variables
lpop --env staging

4️⃣ Run commands without .env files

# Run any command with keychain variables loaded
lpop env -- npm start
lpop env -- node server.js
lpop env -- bun dev

# Use with specific environments
lpop env --env production -- npm run build

🎨 Visual Examples

📥 Adding Variables

$ lpop .env

📂 Reading .env file...
🔐 Storing in: lpop://acme/app

✅ Added 3 variables:
• DATABASE_URL
• API_KEY
• JWT_SECRET

📤 Getting Variables with .env.example Template

When you have a .env.example file, lpop uses it as a template:

.env.example:

# Database configuration
DATABASE_URL=
DB_PASSWORD=

# API configuration
API_KEY=
API_SECRET=

Running lpop produces .env.local:

# Database configuration
DATABASE_URL=postgres://localhost:5432/mydb
DB_PASSWORD=

# API configuration
API_KEY=sk-1234567890abcdef
API_SECRET=

# Additional variables from keychain
EXTRA_VAR=some_value

🔄 Switching Environments

$ lpop --env production

🔐 Repository: github.com/acme/app
🌍 Environment: production

✅ 3 variables written to .env.local using .env.example template

🚀 Running Commands with Keychain Variables

$ lpop env -- npm start

Running "npm start" with 3 variables from lpop://acme/app

> my-app@1.0.0 start
> node server.js

🚀 Server running on port 3000 with API_KEY loaded from keychain

➕ Add Variables

lpop add .env                    # From file
lpop add "DB_URL=postgres://..." # Single variable
lpop add .env --env production   # To specific environment

📖 Get Variables

lpop get                         # All variables to .env.local
lpop get API_KEY                 # Specific variable
lpop get --env staging           # From specific environment

🔄 Update Variables

lpop update .env                 # From file
lpop update "API_KEY=newsecret"  # Single variable

🗑️ Remove Variables

lpop remove API_KEY              # Single variable
lpop clear --confirm             # All variables (with confirmation)

📋 List Stored Repos

lpop list                        # Show all stored repositories

🚀 Run Commands

lpop env                         # Show variables that would be loaded
lpop env -- npm start            # Run with keychain variables
lpop env --env prod -- bun build # Use specific environment

🎯 Common Use Cases

🔧 Development Workflow

# 1. Clone a project
git clone https://github.com/acme/project.git
cd project

# 2. Get the development environment variables
lpop

# 3. Start developing!
npm run dev

🛡️ Security-First Development (No .env files)

# 1. Store your secrets once in keychain
lpop API_KEY=sk-secret123
lpop DATABASE_URL=postgres://localhost:5432/mydb

# 2. Delete .env files completely
rm .env .env.local .env.development

# 3. Run any command with variables from keychain
lpop env -- npm start
lpop env -- bun dev
lpop env -- python app.py

# Variables are loaded securely without ever touching disk!

🚢 Managing Multiple Environments

# Store different configs for each environment
lpop .env.development --env development
lpop .env.staging --env staging
lpop .env.production --env production

# Switch between them easily
lpop --env development  # When developing
lpop --env staging      # When testing
lpop --env production   # When debugging prod

🔒 Security Features

✅ Access Control: Protected by your system's authentication

🤔 FAQs

Where are my variables stored?

Variables are stored in your operating system's secure credential storage:

🍎 macOS: Keychain Access
🪟 Windows: Credential Manager
🐧 Linux: Secret Service API (gnome-keyring, KWallet, etc.)

What happens if I'm not in a git repository?

lpop will use the current directory name as the project identifier. Your variables will be stored as local/dirname?env=development.

Can I share variables with my team?

A share feature is coming real soon. For now, to share with your team:

Export variables: lpop .env.share
Share the file securely (encrypted email, password manager, etc.)
Team members import: lpop .env.share

How do I migrate from .env files?

Simply run lpop .env in each project directory. Your existing .env files will be imported into the secure keychain.

How does the .env.example template work?

When you run lpop and a .env.example file exists:

Template Structure: Maintains organization and comments from .env.example
Variable Matching: Keychain variables matching template keys get values inserted
Additional Variables: Extra keychain variables are added at the end in alphabetical order
Fallback: If .env.example doesn't exist, uses standard format

What's the difference between `lpop` and `lpop env`?

lpop: Exports variables to a .env.local file on disk (traditional approach)
lpop env -- <command>: Runs commands with variables loaded directly from keychain (no files created)

Use lpop env when you want maximum security - no secrets ever touch disk. Perfect for security-conscious teams or when working with sensitive production data.

🛠️ Troubleshooting

🍎 macOS Keychain Prompts

When switching between bun dev and the installed binary, macOS may prompt for keychain access. This is normal - the system sees them as different applications.

🔑 Permission Denied

If you get permission errors, make sure you have access to your system's keychain/credential manager.
